Attributes for orders

When specifying the orders, you can set properties for each—such as its name or service time—using the following attributes:

• ObjectID

  The system-managed ID field.

• Name

  The name of the order. The name must be unique. If the name is left null, a name is automatically generated at solve time.

• Description

  The descriptive information about the order. This can contain any textual information for the order and has no restrictions for uniqueness. You may want to store a client's ID number in the Name field and the client's actual name or address in the Description field.

• ServiceTime

  This property specifies the amount of time that will be spent at the network location when the route visits it; that is, it stores the impedance value for the network location. A zero or null value indicates that the network location requires no service time.

  The unit for this field value is specified by the time_units parameter.

• TimeWindowStart1

  The beginning time of the first time window for the network location. This field can contain a null value; a null value indicates no beginning time.

  A time window only states when a vehicle can arrive at an order; it doesn't state when the service time must be completed. To account for service time and departure before the time window ends, subtract ServiceTime from the TimeWindowEnd1 field.

  The time window fields (TimeWindowStart1, TimeWindowEnd1, TimeWindowStart2, and TimeWindowEnd2) must be specified in a date field as an integer that represents the number of milliseconds since epoch (January 1, 1970) and not as date-time values. The time zone for time window fields is specified using the time_zone_usage_for_time_fields parameter. For example, if the orders are located in the Pacific standard time zone and you want the time window to start at 8:00 a.m. (local time) on November 18, 2019, specify the value for the TimeWindowStart1 field as milliseconds since epoch for this date and time, which is 1574064000000. Specify the time_zone_usage_for_time_fields parameter value as GEO_LOCAL.

  When solving a problem that spans multiple time zones, each order's time-window values refer to the time zone in which the order is located.

• TimeWindowEnd1

  The ending time of the first window for the network location. This field can contain a null value; a null value indicates no ending time.

• TimeWindowStart2

  The beginning time of the second time window for the network location. This field can contain a null value; a null value indicates that there is no second time window.

  If the first time window is null as specified by the TimeWindowStart1 and TimeWindowEnd1 fields, the second time window must also be null.

  If both time windows are non null, they can't overlap. Also, the second time window must occur after the first.

• TimeWindowEnd2

  The ending time of the second time window for the network location. This field can contain a null value.

  When TimeWindowStart2 and TimeWindowEnd2 are both null, there is no second time window.

  When TimeWindowStart2 is not null but TimeWindowEnd2 is null, there is a second time window that has a starting time but no ending time. This is valid.

• MaxViolationTime1

  A time window is considered violated if the arrival time occurs after the time window has ended. This field specifies the maximum allowable violation time for the first time window of the order. It can contain a zero value but can't contain negative values. A zero value indicates that a time window violation at the first time window of the order is unacceptable; that is, the first time window is hard. Conversely, a null value indicates that there is no limit on the allowable violation time. A nonzero value specifies the maximum amount of lateness; for example, a route can arrive at an order up to 30 minutes beyond the end of its first time window.

  The unit for this field value is specified by the time_units parameter

  Time window violations can be tracked and weighted by the solver. Consequently, you can direct the VRP solver to do one of the following:

  • Minimize the overall violation time regardless of the increase in travel cost for the fleet.
  • Find a solution that balances overall violation time and travel cost.
  • Ignore the overall violation time and minimize the travel cost for the fleet.

  By assigning an importance level for the time_window_factorparameter, you are essentially choosing one of these options. In any case, the solver will return an error if the value set for MaxViolationTime1 is surpassed.

• MaxViolationTime2

  The maximum allowable violation time for the second time window of the order. This field is analogous to the MaxViolationTime1 field.

• InboundArriveTime

  Defines when the item to be delivered to the order will be ready at the starting depot.

  Note:

  The VRP solver honors InboundArriveTime regardless of the DeliveryQuantities value.

  The order can be assigned to a route only if the inbound arrive time precedes the route's latest start time value; this way, the route cannot leave the depot before the item is ready to be loaded onto it.

  Note:

  The route's start time, which includes service times, must occur after the inbound arrive time. If a route begins before an order's inbound arrive time, the order cannot be assigned to the route. The assignment is invalid even if the route has a start-depot service time that lasts until after the inbound arrive time.

  If an outbound depart time is also specified, its time value must occur after the inbound arrive time.

  This field can help model scenarios involving inbound-wave transshipments. For example, a job at an order requires special materials that are not currently available at the depot. The materials are being shipped from another location and will arrive at the depot at 11:00 a.m. To ensure a route that leaves before the shipment arrives isn't assigned to the order, the order's inbound arrive time is set to 11:00 a.m. The special materials arrive at 11:00 a.m., they are loaded onto the vehicle, and the vehicle departs from the depot to visit its assigned orders.

  Note:

  This time field can contain a time-only value or a date and time value. If a time-only value is set (for example, 11:00 AM), the date is assumed to be the default date set for the analysis. The default date is ignored, however, when any time field in the Depots, Routes, Orders, or Breaks includes a date with the time. In that case, specify all such fields with a date and time (for example, 7/11/2015 11:00 AM).

• OutboundDepartTime

  Defines when the item to be picked up at the order must arrive at the ending depot.

  Note:

  The VRP solver honors OutboundDepartTime regardless of the PickupQuantities value.

  The order can be assigned to a route only if the route can visit the order and reach its end depot before the specified outbound depart time.

  Note:

  The route's end time, including service times, must occur before the outbound depart time. If a route reaches a depot but doesn't complete its end-depot service time prior to the order's outbound depart time, the order cannot be assigned to the route.

  If an inbound arrive time is also specified, its time value must occur before the outbound depart time.

  This field can help model scenarios involving outbound-wave transshipments. For instance, a shipping company sends out delivery trucks to pick up packages from orders and bring them into a depot where they are forwarded on to other facilities, en route to their final destination. At 3:00 p.m. every day, a semitrailer stops at the depot to pick up the high-priority packages and take them directly to a central processing station. To avoid delaying the high-priority packages until the next day's 3:00 p.m. trip, the shipping company tries to have delivery trucks pick up the high-priority packages from orders and bring them to the depot before the 3:00 p.m. deadline. This is done by setting the outbound depart time to 3:00 p.m.

  Note:

  This time field can contain a time-only value or a date and time value. If a time-only value is set (for example, 11:00 AM), the date is assumed to be the default date set for the analysis. The default date is ignored, however, when any time field in the Depots, Routes, Orders, or Breaks includes a date with the time. In that case, specify all such fields with a date and time (for example, 7/11/2015 11:00 AM).

• DeliveryQuantities

  The size of the delivery. You can specify size in any dimension, such as weight, volume, or quantity. You can also specify multiple dimensions, for example, weight and volume.

  Enter delivery quantities without indicating units. For example, if a 300-pound object needs to be delivered to an order, enter 300. You will need to remember that the value is in pounds.

  If you are tracking multiple dimensions, separate the numeric values with a space. For example, if you are recording the weight and volume of a delivery that weighs 2,000 pounds and has a volume of 100 cubic feet, enter 2000 100. Again, you need to remember the units—in this case, pounds and cubic feet. You also need to remember the sequence in which the values and their corresponding units are entered.

  Make sure that Capacities for Routes and DeliveryQuantities and PickupQuantities for Orders are specified in the same manner; that is, the values must be in the same units. If you are using multiple dimensions, the dimensions must be listed in the same sequence for all parameters. For example, if you specify weight in pounds, followed by volume in cubic feet for DeliveryQuantities, the capacity of your routes and the pickup quantities of your orders must be specified the same way: weight in pounds, then volume in cubic feet. If you combine units or change the sequence, you will get unwanted results with no warning messages.

  An empty string or null value is equivalent to all dimensions being infinity. If the string has an insufficient number of values in relation to the capacity count or dimensions being tracked, the remaining values are treated as infinity. Delivery quantities can't be negative.

• PickupQuantities

  The size of the pickup. You can specify size in any dimension, such as weight, volume, or quantity. You can also specify multiple dimensions, for example, weight and volume. You cannot, however, use negative values. This field is analogous to the DeliveryQuantities field of Orders.

  In the case of an exchange visit, an order can have both delivery and pickup quantities.

• Revenue

  The income generated if the order is included in a solution. This field can contain a null value—a null value indicates zero revenue—but it can't have a negative value.

  Revenue is included in optimizing the objective function value but is not part of the solution's operating cost; that is, the TotalCost field in the routes never includes revenue in its output. However, revenue weights the relative importance of servicing orders.

• SpecialtyNames

  A space-separated string containing the names of the specialties required by the order. A null value indicates that the order doesn't require specialties.

  The spelling of any specialties listed in the Orders and Routes classes must match exactly so that the VRP solver can link them together.

  To illustrate what specialties are and how they work, assume a lawn care and tree trimming company has a portion of its orders that requires a bucket truck to trim tall trees. The company enters BucketTruck in the SpecialtyNames field for these orders to indicate their special need. SpecialtyNames is left null for the other orders. Similarly, the company also enters BucketTruck in the SpecialtyNames field of routes that are driven by trucks with hydraulic booms. It leaves the field null for the other routes. At solve time, the VRP solver assigns orders without special needs to any route, but it only assigns orders that need bucket trucks to routes that have them.

• AssignmentRule

  Specifies the rule for assigning the order to a route. The field value is specified as one of the following integers (use the numeric code, not the name in parentheses):

  • 0 (Exclude)—The order will be excluded from the subsequent solve operation.
  • 1 (Preserve route and relative sequence)—The solver must always assign the order to the preassigned route at the preassigned relative sequence during the solve operation. If this assignment rule can't be followed, it results in an order violation. With this setting, only the relative sequence is maintained, not the absolute sequence. To illustrate what this means, imagine there are two orders: A and B. They have sequence values of 2 and 3, respectively. If you set their AssignmentRulefield values to Preserve route and relative sequence, the sequence values for A and B may change after solving because other orders, breaks, and depot visits can be sequenced before, between, or after A and B. However, B cannot be sequenced before A.
  • 2 (Preserve route)—The solver must always assign the order to the preassigned route during the solve operation. A valid sequence must also be set even though the sequence may or may not be preserved. If the order can't be assigned to the specified route, it results in an order violation.
  • 3 (Override)—The solver tries to preserve the route and sequence preassignment for the order during the solve operation. However, a new route or sequence for the order may be assigned if it helps minimize the overall value of the objective function. This is the default value.
  • 4 (Anchor first)—The solver ignores the route and sequence preassignment (if any) for the order during the solve operation. It assigns a route to the order and makes it the first order on that route to minimize the overall value of the objective function.
  • 5 (Anchor last)—The solver ignores the route and sequence preassignment (if any) for the order during the solve operation. It assigns a route to the order and makes it the last order on that route to minimize the overall value of the objective function.

  This field can't contain a null value.

• CurbApproach

  Specifies the direction a vehicle can arrive at and depart from the order. One of the integers listed in the Coded value column in the following table must be specified as a value of this attribute. The values in the Setting column are the descriptive names for the CurbApproach attribute values that you may have come across when using ArcGIS Network Analyst extension software.

  Setting	Coded value	Description
  Either side of vehicle	0	The vehicle can approach and depart the order in either direction, so a U-turn is allowed at the order. This setting can be chosen if it is possible and desirable for a vehicle to turn around at the order. This decision may depend on the width of the road and the amount of traffic or whether the order has a parking lot where vehicles can pull in and turn around.
  Right side of vehicle	1	When the vehicle approaches and departs the order, the order must be on the right side of the vehicle. A U-turn is prohibited. This is typically used for vehicles such as buses that must arrive with the bus stop on the right side.
  Left side of vehicle	2	When the vehicle approaches and departs the order, the order must be on the left side of the vehicle. A U-turn is prohibited. This is typically used for vehicles such as buses that must arrive with the bus stop on the left side.
  No U-Turn	3	When the vehicle approaches the order, the order can be on either side of the vehicle; however, when it departs, the vehicle must continue in the same direction it arrived. A U-turn is prohibited.

  The CurbApproach attribute is designed to work with both kinds of national driving standards: right-hand traffic (United States) and left-hand traffic (United Kingdom). First, consider an order on the left side of a vehicle. It is always on the left side regardless of whether the vehicle travels on the left or right half of the road. What may change with national driving standards is your decision to approach an order from one of two directions, that is, so it ends up on the right or left side of the vehicle. For example, if you want to arrive at an order and not have a lane of traffic between the vehicle and the order, choose 1 (Right side of vehicle) in the United States and 2 (Left side of vehicle) in the United Kingdom.

  

  

• RouteName

  The name of the route to which the order is assigned.

  This field is used to preassign an order to a specific route. It can contain a null value, indicating that the order is not preassigned to any route, and the solver identifies the best possible route assignment for the order. If this is set to null, the Sequence field must also be set to null.

  After a solve operation, if the order is routed, the RouteName field contains the name of the route to which the order is assigned.

• Sequence

  This indicates the sequence of the order on its assigned route.

  This field is used to specify the relative sequence of an order on the route. This field can contain a null value specifying that the order can be placed anywhere along the route. A null value can only occur together with a null RouteName value.

  The input sequence values are positive and unique for each route (shared across renewal depot visits, orders, and breaks) but do not need to start from 1 or be contiguous.

  After a solve operation, the Sequence field contains the sequence value of the order on its assigned route. Output sequence values for a route are shared across depot visits, orders, and breaks; start from 1 (at the starting depot); and are consecutive. The smallest possible output sequence value for a routed order is 2, since a route always begins at a depot.

• Bearing

  The direction in which a point is moving. The units are degrees and are measured clockwise from true north. This field is used in conjunction with the BearingTol field.

  Bearing data is usually sent automatically from a mobile device equipped with a GPS receiver. Try to include bearing data if you are loading an input location that is moving, such as a pedestrian or a vehicle.

  Using this field tends to prevent adding locations to the wrong edges, which can occur when a vehicle is near an intersection or an overpass, for example. Bearing also helps the tool determine on which side of the street the point is.

  Learn more about bearing and bearing tolerance

• BearingTol

  The bearing tolerance value creates a range of acceptable bearing values when locating moving points on an edge using the Bearing field. If the Bearing field value is within the range of acceptable values that are generated from the bearing tolerance on an edge, the point can be added as a network location there; otherwise, the closest point on the next-nearest edge is evaluated.

  The units are in degrees, and the default value is 30. Values must be greater than 0 and less than 180. A value of 30 means that when Network Analyst attempts to add a network location on an edge, a range of acceptable bearing values is generated 15 degrees to either side of the edge (left and right) and in both digitized directions of the edge.

  Learn more about bearing and bearing tolerance

• NavLatency

  This field is only used in the solve process if the Bearing and BearingTol fields also have values; however, entering a NavLatency field value is optional, even when values are present in Bearing and BearingTol. NavLatency indicates how much cost is expected to elapse from the moment GPS information is sent from a moving vehicle to a server and the moment the processed route is received by the vehicle's navigation device.

  The units of NavLatency are the same as the units of the impedance attribute.

}

Attributes for depots

When specifying the depots, you can set properties for each—such as its name or service time—using the following attributes:

• ObjectID

  The system-managed ID field.

• Name

  The name of the depot. The StartDepotName and EndDepotName fields on routes reference the names you specify here. It is also referenced by the route renewals, when used.

  Depot names are not case sensitive but must be nonempty and unique.

• Description

  The descriptive information about the depot location. This can contain any textual information and has no restrictions for uniqueness.

  For example, if you want to note which region a depot is in or the depot's address and telephone number, you can enter the information here rather than in the Name field.

• TimeWindowStart1

  The beginning time of the first time window for the network location. This field can contain a null value; a null value indicates no beginning time.

  The time window fields (TimeWindowStart1, TimeWindowEnd1, TimeWindowStart2, and TimeWindowEnd2) must be specified in a date field as an integer that represents the number of milliseconds since epoch (January 1, 1970), not as date-time values. The time zone for time window fields is specified using the time_zone_usage_for_time_fields parameter. For example, if the orders are located in the Pacific standard time zone and you want to specify that the time window start at 8:00 a.m. local time on November 18, 2019, the value for the TimeWindowStart1 field should be specified as milliseconds since epoch for this date and time, which is 1574064000000. You also should specify the time_zone_usage_for_time_fields parameter value as GEO_LOCAL.

  When solving a problem that spans multiple time zones, each depot's time-window values refer to the time zone in which the depot is located.

• TimeWindowEnd1

  The ending time of the first window for the network location. This field can contain a null value; a null value indicates no ending time.

• TimeWindowStart2

  The beginning time of the second time window for the network location. This field can contain a null value; a null value indicates that there is no second time window.

  If the first time window is null, as specified by the TimeWindowStart1 and TimeWindowEnd1 fields, the second time window must also be null.

  If both time windows are not null, they can't overlap. Also, the second time window must occur after the first.

• TimeWindowEnd2

  The ending time of the second time window for the network location. This field can contain a null value.

  When TimeWindowStart2 and TimeWindowEnd2 are both null, there is no second time window.

  When TimeWindowStart2 is not null but TimeWindowEnd2 is null, there is a second time window that has a starting time but no ending time. This is valid.

• CurbApproach

  Specifies the direction a vehicle can arrive at and depart from the depot. One of the integers listed in the Coded value column in the following table must be specified as a value of this attribute. The values in the Setting column are the descriptive names for CurbApproach attribute values that you may have come across when using the ArcGIS Network Analyst extension.

  Setting	Coded value	Description
  Either side of vehicle	0	The vehicle can approach and depart the depot in either direction, so a U-turn is allowed at the depot. This setting can be chosen if it is possible and desirable for a vehicle to turn around at the depot. This decision may depend on the width of the road and the amount of traffic or whether the depot has a parking lot where vehicles can pull in and turn around.
  Right side of vehicle	1	When the vehicle approaches and departs the depot, the depot must be on the right side of the vehicle. A U-turn is prohibited. This is typically used for vehicles such as buses that must arrive with the bus stop on the right side.
  Left side of vehicle	2	When the vehicle approaches and departs the depot, the depot must be on the left side of the vehicle. A U-turn is prohibited. This is typically used for vehicles such as buses that must arrive with the bus stop on the left side.
  No U-Turn	3	When the vehicle approaches the depot, the depot can be on either side of the vehicle; however, when it departs, the vehicle must continue in the same direction it which it arrived. A U-turn is prohibited.

  The CurbApproach attribute is designed to work with both kinds of national driving standards: right-hand traffic (United States) and left-hand traffic (United Kingdom). First, consider a depot on the left side of a vehicle. It is always on the left side regardless of whether the vehicle travels on the left or right half of the road. What may change with national driving standards is your decision to approach a depot from one of two directions, that is, so it ends up on the right or left side of the vehicle. For example, if you want to arrive at a depot and not have a lane of traffic between the vehicle and the depot, choose 1 (Right side of vehicle) in the United States and 2 (Left side of vehicle) in the United Kingdom.

}

Attributes for routes

When specifying the routes, you can specify additional properties, such as their names or capacities, using attributes. The routes parameter can be specified with the following attributes:

• Name

  The name of the route. The name must be unique.

  The service generates a unique name if the attribute value is null. Therefore, specifying a value is optional in most cases. However, you must specify a name if the analysis includes breaks, route renewals, route zones, or orders that are preassigned to a route because the route name is used as a foreign key in these cases. Route names are not case sensitive.

• StartDepotName

  The name of the starting depot for the route. This attribute is a foreign key to the Name attribute in the depots parameter, so the values must match.

  If the StartDepotName value is null, the route will begin from the first order assigned. Omitting the start depot is useful when the vehicle's starting location is unknown or irrelevant to the routing problem. However, when StartDepotName is null, EndDepotName cannot also be null.

  Virtual start depots are not allowed if orders or depots are in multiple time zones.

  If the route is making deliveries and StartDepotName is null, it is assumed the cargo is loaded on the vehicle at a virtual depot before the route begins. For a route that has no renewal visits, its delivery orders (those with nonzero DeliveryQuantities values in the orders parameter) are loaded at the start depot or virtual depot. For a route that has renewal visits, only the delivery orders before the first renewal visit are loaded at the start depot or virtual depot.

• EndDepotName

  The name of the ending depot for the route. This attribute is a foreign key to the Name attribute in the depots parameter, so the values must match.

• StartDepotServiceTime

  The service time at the starting depot. This can be used to model the time spent loading the vehicle. This attribute can contain a null value; a null value indicates zero service time. The unit for this attribute value is specified by the time_units parameter.

• EndDepotServiceTime

  The service time at the ending depot. This can be used to model the time spent unloading the vehicle. This attribute can contain a null value; a null value indicates zero service time. The unit for this attribute value is specified by the time_units parameter.

  The service times at the start and end depots are fixed values (given by the StartDepotServiceTime and EndDepotServiceTime attribute values) and do not take into account the actual load for a route. For example, the time taken to load a vehicle at the starting depot may depend on the size of the orders. The depot service times can be given values corresponding to a full truckload or an average truckload, or you can make your own time estimate.

• EarliestStartTime

  The earliest allowable starting time for the route. This is used by the service in conjunction with the time window of the starting depot for determining feasible route start times.

  This attribute can't contain null values and has a default time-only value of 8:00 AM on the date specified by the default_date parameter or the current date if unspecified.

• LatestStartTime

  The latest allowable starting time for the route. This attribute can't contain null values and has a default time-only value of 10:00 AM; the default value is interpreted as 10:00 a.m. on the date specified by the default_date parameter.

  The value for the EarliestStartTime and LatestStartTime attributes is specified in a date field as an integer that represents the number of milliseconds since epoch (January 1, 1970).

  The time zone is specified using the time_zone_usage_for_time_fields parameter. If set to GEO_LOCAL, the time is in the time zone where the route's depot is located. This is useful if the routes span multiple time zones but they all start at a consistent time (for example, 8:00 a.m. in the depot's time zone). If the parameter is set to UTC, the time is based on UTC. This is useful if you don't know the time zone of an individual route's depot but know its absolute time (for example, the time window starts an hour from now).

• ArriveDepartDelay

  This stores the amount of travel time needed to accelerate the vehicle to normal travel speeds, decelerate it to a stop, and move it off and on the network (for example, in and out of parking). By including an ArriveDepartDelay value, the service is deterred from sending many routes to service physically coincident orders.

  The cost for this attribute is incurred between visits to noncoincident orders, depots, and route renewals. For example, when a route starts from a depot and visits the first order, the total arrive/depart delay is added to the travel time. The same is true when traveling from the first order to the second order. If the second and third orders are coincident, the ArriveDepartDelay value is not added between them because the vehicle doesn't need to move. If the route travels to a route renewal, the value is added to the travel time again.

  Although a vehicle needs to slow down and stop for a break and accelerate afterward, the service cannot add the ArriveDepartDelay value for breaks. This means that if a route leaves an order, stops for a break, and continues to the next order, the arrive/depart delay is added only once, not twice.

  For example, there are five coincident orders in a high-rise building, and they are serviced by three routes. This means three arrive/depart delays would be incurred; that is, three drivers would need to separately find parking places and enter the same building. However, if the orders could be serviced by just one route, only one driver would need to park and enter the building—only one arrive/depart delay would be incurred. Since the service tries to minimize cost, it will try to limit the arrive/depart delays and use the single-route option. (Multiple routes may need to be sent when other constraints—such as specialties, time windows, or capacities—require it.)

  The unit for this attribute value is specified by the time_units parameter.

• Capacities

  The maximum capacity of the vehicle. You can specify capacity in any dimension, such as weight, volume, or quantity. You can also specify multiple dimensions, for example, weight and volume.

  Specify capacities without indicating units. For example, if a vehicle can carry a maximum of 40,000 pounds, specify 40000 as the value for the Capacities attribute. You need to remember for future reference that the value is in pounds.

  If you are tracking multiple dimensions, separate the numeric values with a space. For example, if you are recording both weight and volume and the vehicle can carry a maximum weight of 40,000 pounds and a maximum volume of 2,000 cubic feet, specify 40000 2000 for Capacities. Again, you need to remember the units. You also need to remember the sequence in which the values and their corresponding units are specified (pounds followed by cubic feet in this case).

  Remembering the units and the unit sequence is important for a couple of reasons: first, so you can reinterpret the information later, and second, so you can properly enter values for the DeliveryQuantities and PickupQuantities attributes in the orders parameter. The service simultaneously checks the Capacities, DeliveryQuantities, and PickupQuantities attributes to make sure that a route doesn't become overloaded. Since units can't be entered in the field, the service can't make unit conversions, so you need to specify the values for the three attributes using the same units and the same unit sequence to ensure the values are correctly interpreted. If you combine units or change the sequence in any of the three attributes, you will get unwanted results without receiving any warning messages. It is recommended that you set up a unit and unit-sequence standard before you start and refer to it when specifying values for these three attributes.

  An empty string or null value is equivalent to all values being zero. Capacity values can't be negative.

  If the Capacities string has an insufficient number of values in relation to the DeliveryQuantities or PickupQuantities attributes in the orders parameter, the remaining values are treated as zero.

  Caution:

  The service only performs a simple Boolean test to determine whether capacities are exceeded. If a route's capacity value is greater than or equal to the total quantity being carried, it is assumed the cargo fits in the vehicle. This may be incorrect, depending on the actual shape of the cargo and the vehicle. For example, the service allows you to fit a 1,000-cubic-foot sphere into a 1,000-cubic-foot truck that is 8 feet wide. In reality, however, since the sphere is 12.6 feet in diameter, it won't fit in the 8-foot wide truck.

• FixedCost

  A fixed monetary cost that is incurred only if the route is used in a solution (that is, it has orders assigned to it). This attribute can contain null values; a null value indicates zero fixed cost. This cost is part of the total route operating cost.

• CostPerUnitTime

  The monetary cost incurred per unit of work time for the total route duration, including travel times as well as service times and wait times at orders, depots, and breaks. This attribute can't contain a null value and has a default value of 1.0. The unit for this attribute value is specified by the time_units parameter.

• CostPerUnitDistance

  The monetary cost incurred per unit of distance traveled for the route length (total travel distance). This attribute can contain null values; a null value indicates zero cost. The unit for this attribute value is specified by the distance_units parameter.

• OverTimeStartTime

  The duration of regular work time before overtime computation begins. This attribute can contain null values; a null value indicates that overtime does not apply. The unit for this attribute value is specified by the time_units parameter.

  For example, if the driver is to be paid overtime pay when the total route duration extends beyond eight hours, OvertimeStartTime is specified as 480 (8 hours * 60 minutes/hour), given the time_units parameter is set to Minutes.

• CostPerUnitOvertime

  The monetary cost incurred per time unit of overtime work. This attribute can contain null values; a null value indicates that the CostPerUnitOvertime value is the same as the CostPerUnitTime value. The unit for this attribute value is specified by the time_units parameter.

• MaxOrderCount

  The maximum allowable number of orders on the route. This attribute can't contain null values and has a default value of 30.

• MaxTotalTime

  The maximum allowable route duration. The route duration includes travel times as well as service and wait times at orders, depots, and breaks. This attribute can contain null values; a null value indicates that there is no constraint on the route duration. The unit for this attribute value is specified by the time_units parameter.

• MaxTotalTravelTime

  The maximum allowable travel time for the route. The travel time includes only the time spent driving on the streets and does not include service or wait times. This attribute can contain null values; a null value indicates there is no constraint on the maximum allowable travel time. This attribute value can't be larger than the MaxTotalTime attribute value. The unit for this attribute value is specified by the time_units parameter.

• MaxTotalDistance

  The maximum allowable travel distance for the route. This attribute can contain null values; a null value indicates that there is no constraint on the maximum allowable travel distance. The unit for this attribute value is specified by the distance_units parameter.

• SpecialtyNames

  A space-separated string containing the names of the specialties supported by the route. A null value indicates that the route does not support any specialties. This attribute is a foreign key to the SpecialtyNames attribute in the orders parameter, so the values must match.

  For example, a lawn care and tree trimming company has a portion of its orders that requires a bucket truck to trim tall trees. The company specifies BucketTruck as the value for the SpecialtyNames attribute for these orders to indicate their special need. SpecialtyNames is left as null for the other orders. Similarly, the company also specifies BucketTruck as the value for the SpecialtyNames attribute for the routes that are driven by trucks with hydraulic booms. It leaves the attribute value as null for the other routes. When finding the solution, the service assigns orders without special needs to any route, but it only assigns orders that need bucket trucks to routes that have them.

• AssignmentRule

  Specifies whether the route can be used when solving the problem. The attribute value should be specified as one of the following integer values:

  • 0—The route is excluded from the solution.
  • 1—The route is included when finding the solution. This is the default value.

      }
    }
  ]
}

Attributes for breaks

When specifying the breaks, you can specify additional properties for breaks, such as their time windows or duration, using attributes. The breaks parameter can be specified with the following attributes:

• RouteName

  The name of the route that the break applies to. Although a break is assigned to exactly one route, many breaks can be assigned to the same route. This attribute is a foreign key to the Name attribute in the routes parameter, so the values must match. The attribute cannot have a null value.

• Precedence

  Specifies the values to sequence the breaks of a given route. Breaks with a precedence value of 1 occur before those with a value of 2, and so on. All breaks must have a precedence value, regardless of whether they are time window, maximum travel time, or maximum work time breaks. The default value for this attribute is 1.

• ServiceTime

  The duration of the break. The units for this attribute value are specified by the time_units parameter. This attribute can't contain a null value. The default value for this attribute is 60.

• TimeWindowStart

  The starting time of the break's time window. Specifying this attribute indicates that the service will consider the breaks as time window breaks. The attribute value is specified as a numeric value representing the milliseconds since midnight, January 1, 1970.

  If this attribute is null and the TimeWindowEnd attribute has a valid time-of-day value, the break is allowed to start anytime before the TimeWindowEnd value.

  The default value for this attribute is null.

• TimeWindowEnd

  The ending time of the break's time window. Specifying this attribute indicates that the service will consider the breaks as time window breaks. The attribute value is specified as a numeric value representing the milliseconds since midnight, January 1, 1970.

  If this attribute is null and the TimeWindowStart attribute has a valid time-of-day value, the break is allowed to start anytime after the TimeWindowStart value.

  The default value for this attribute is null.

  For both the TimeWindowStart and TimeWindowEnd attributes, the time zone is specified by the time_zone_usage_for_time_fields parameter. If the parameter is set to GEO_LOCAL, the time is in the time zone where the route's depot is located. This is useful if the routes span multiple time zones but they all break at a consistent time (for example, 12:00 p.m. in the depot's time zone). If the parameter is set to UTC, the time is based on UTC time. This is useful if you don't know the time zone of an individual route's depot but know the absolute time for each break (for example, the break starts an hour from now).

  Caution:

  If either the TimeWindowStart or the TimeWindowEnd attribute has values, the MaxTravelTimeBetweenBreaks and MaxCumulWorkTime attributes must be null; also, all other breaks must have null values for the MaxTravelTimeBetweenBreaks and MaxCumulWorkTime attributes for the request to succeed. The service will also return an error if a route has multiple breaks with overlapping time windows.

• MaxViolationTime

  Specifies the maximum allowable violation time for a time window break. A time window is considered violated if the arrival time falls outside of the time range. The units for this attribute value are specified by the time_units parameter.

  A zero value indicates that the time window cannot be violated; that is, the time window is hard. A nonzero value specifies the maximum amount of lateness; for example, the break can begin up to 30 minutes beyond the end of its time window, but the lateness is penalized pursuant to the time_window_factor parameter. A null value indicates that there is no limit on the allowable violation time.

  Caution:

  For the request to succeed, if MaxTravelTimeBetweenBreaks or MaxCumulWorkTime has a value, MaxViolationTime must be null.

  The default value for this attribute is null.

• MaxTravelTimeBetweenBreaks

  The maximum amount of travel time that can be accumulated before the break is taken. Specifying this attribute indicates that the service will consider the breaks as travel time breaks. The travel time is accumulated either from the end of the previous break or, if a break has not yet been taken, from the start of the route. If this is the route's final break, this attribute also indicates the maximum travel time that can be accumulated from the final break to the end depot.

  The MaxTravelTimeBetweenBreaks attribute is designed to limit how long a person can drive until a break is required. For instance, if the time_units parameter is set to Minutes, and MaxTravelTimeBetweenBreaks has a value of 120, the driver will get a break after two hours of driving. To assign a second break after two more hours of driving, the second break's MaxTravelTimeBetweenBreaks attribute value must be 120.

  The units for this attribute value are specified by the time_units parameter. The default value for this attribute is null.

  Caution:

  For the request to succeed, if the MaxTravelTimeBetweenBreaks attribute has a value, the TimeWindowStart, TimeWindowEnd, MaxViolationTime, and MaxCumulWorkTime attributes must be null.

• MaxCumulWorkTime

  The maximum amount of work time that can be accumulated before the break is taken. Specifying this attribute indicates that the service will consider the breaks as work time breaks. Work time is always accumulated from the beginning of the route. Work time is the sum of travel time and service times at orders, depots, and breaks. However, this excludes wait time, which is the time a route (or driver) spends waiting at an order or depot for a time window to begin.

  The MaxCumulWorkTime attribute limits how long a person can work until a break is required. For instance, if the time_units parameter is set to Minutes, the MaxCumulWorkTime attribute has a value of 120, and the ServiceTime attribute has a value of 15, the driver will get a 15-minute break after two hours of work. If a second break is needed after three more hours of work, specify 315 (five hours and 15 minutes) as the second break's MaxCumulWorkTime value. This number includes the MaxCumulWorkTime and ServiceTime values of the preceding break, along with the three additional hours of work time before granting the second break. To avoid taking maximum work time breaks prematurely, remember that they accumulate work time from the beginning of the route and that work time includes the service time at previously visited depots, orders, and breaks.

  The units for this attribute value are specified by the time_units parameter. The default value for this attribute is null.

  Caution:

  For the request to succeed, if the MaxCumulWorkTime attribute has a value, the TimeWindowStart, TimeWindowEnd, MaxViolationTime, and MaxTravelTimeBetweenBreaks attributes must be null.

• IsPaid

  Specifies whether the break is paid or unpaid. The attribute value is specified as an integer with possible values of 0 or 1. A value of 1 indicates that the time spent at the break is included in the route cost computation and overtime determination. A value of 0 indicates otherwise. The default value for this attribute is 1.

• Sequence

  Indicates the relative sequence of the break on its route. The attribute values must be positive and unique for each route but do not need to start from 1 or be contiguous. In the service output, the Sequence attribute of the out_stops parameter contains the sequence value of the break on its route. This attribute can have null values specifying that the break can be placed anywhere along the route. The default value for this attribute is null.

Examples for breaks

Example 1: Specify time-window-based breaks using JSON structure.

This example shows how to specify time-window-based breaks by specifying the values for the TimeWindowStart and the TimeWindowEnd attributes. The input vehicle routing problem requires that each of three routes have one 30-minute paid break between 12:30 p.m. and 1:30 p.m. The break time window is hard, so the break must start between 12:30 p.m. and 1:30 p.m. and cannot start after 1:30 p.m.

You must specify one break for each route, so you have a total of three features. Specify the appropriate milliseconds since January 1, 1970, for 12:30 p.m. Pacific time on April 23, 2013, as the value for the TimeWindowStart attribute and the appropriate milliseconds since January 1, 1970, for 1:30 p.m. on April 23, 2013, as the value for the TimeWindowEnd attribute. Because the break time window is hard, specify a value of 0 for the MaxViolationTime attribute. Because the break duration is 30 minutes, specify a value of 30 for the ServiceTime attribute assuming the time_units parameter is set to Minutes. For each break, only specify the attribute values required to model the input scenario. The other attribute values are not specified because their default values are adequate in this scenario.

{
  "features": [
    {
      "attributes": {
        "RouteName": "Truck1",
        "TimeWindowStart": 1366745400000,
        "TimeWindowEnd": 1366749000000,

        "MaxViolationTime": 0
      }
    },
    {

        "TimeWindowStart": 1366745400000,
        "TimeWindowEnd": 1366749000000,
        "ServiceTime": 30,
        "MaxViolationTime": 0
      }
    }
  ]
}

Example 2: Specify travel-time-based breaks using JSON structure.

This example shows how to specify travel-time-based breaks by specifying the value for the MaxTravelTimeBetweenBreaks attribute. The input vehicle routing problem requires that the driver for each of the two routes have one 15-minute unpaid break after two hours of driving and another unpaid break after an additional two hours of driving.

You must specify two breaks for each route, so you have a total of four features. The first break for each route has a precedence value of 1 and the second break has a precedence value of 2. As each break on the route must occur after two hours of travel time, specify the MaxTravelTimeBetweenBreaks attribute value as 120 for both breaks on a route assuming that the time_units parameter is set to Minutes. Because the break duration is 15 minutes, specify a value of 15 for the ServiceTime attribute. Because the break is unpaid, specify a value of 0 for the IsPaid attribute. The other attribute values are not specified because their default values are adequate in this scenario.

{
  "features": [
    {
      "attributes": {
        "RouteName": "Truck1",
        "Precedence": 1,
        "ServiceTime": 15,
        "MaxTravelTimeBetweenBreaks": 120,
        "IsPaid": 0
      }
    },
    {
      "attributes": {
        "RouteName": "Truck1",
        "Precedence": 2,
        "ServiceTime": 15,
        "MaxTravelTimeBetweenBreaks": 120,
        "IsPaid": 0
      }
    },
    {
      "attributes": {
        "RouteName": "Truck2",
        "Precedence": 1,
        "ServiceTime": 15,

        "IsPaid": 0
      }
    },
    {
      "attributes": {
        "RouteName": "Truck2",
        "Precedence": 2,
        "ServiceTime": 15,
        "MaxTravelTimeBetweenBreaks": 120,
        "IsPaid": 0
      }
    }
  ]
}

Example 3: Specify work-time-based breaks using JSON structure.

This example shows how to specify work-time-based breaks by specifying the value for the MaxCumulWorkTime attribute. The input vehicle routing problem requires that the driver for each of the two routes have one 15-minute paid break after two hours of work time and a second 15-minute paid break after three hours of work time since the first break.

You must specify two breaks for each route, so you have a total of four features. The first break for each route has a precedence value of 1 and the second break has a precedence value of 2. Because the first break on each route must occur after two hours of work, specify the MaxCumulWorkTime attribute value as 120 for the first break on a route assuming that the time_units parameter is set to Minutes. Because the second break is needed after three more hours of work, specify 315 (five hours and 15 minutes) as the second break's MaxCumulWorkTime value. This number includes the MaxCumulWorkTime and ServiceTime values of the preceding break, along with the three additional hours of work time before granting the second break (120+15+180=315). Because the break duration is 15 minutes, specify a value of 15 for the ServiceTime attribute. The other attribute values are not specified because their default values are adequate in this scenario.

Attributes for route_zones

When specifying the route_zones parameter, you can specify additional information about route zones, such as the name of the route to which the route zone applies, using attributes. The route_zones parameter can be specified with the following attributes:

• RouteName

  The name of the route to which this zone applies. A route zone can have a maximum of one associated route. This attribute is a foreign key to the Name attribute in the routes parameter, so the values must match. The attribute cannot have a null value.

• IsHardZone

  Specifies whether the route zone is hard or soft. The attribute value is specified as an integer with possible values of 0 or 1. A value of 1 indicates that the route zone is hard; that is, an order that falls outside of the route zone area can't be assigned to the route. A value of 0 indicates that such orders can still be assigned, but the cost of servicing the order is weighted by a function that is based on the Euclidean distance from the route zone. This means that as the straight-line distance from the soft zone to the order increases, the likelihood of the order being assigned to the route decreases.

  Note:

  Even though a route associated with a hard route zone can only service orders inside the route zone, other routes can still enter and service the orders inside the same zone. This is because route zones restrict the route, not the orders. If you want to assign all the orders in an area exclusively to one route, don't use route zones; instead, for all the orders in an area, change the RouteName attribute on the orders parameter to the proper route, and set the AssignmentRule attribute for the orders to 2.

Examples for route_zones

Example 1: Specify route zones using JSON structure.

The example shows how to add route zones associated with the routes in a vehicle routing problem. The two routes in the input vehicle routing problem are operated by vans that are only licensed to service orders in a predetermined area and cannot service orders that are outside of the route zone. The IsHardZone attribute value is set to 1 to ensure that the vans are only assigned orders that are within the route zones.

The first zone is a single-part polygon feature composed of four points. The second zone is a two-part polygon feature in which both parts are composed of four points. The barrier geometries are in the spatial reference of the network dataset. The spatialReference property is not required.

Example 2: Specify route zones using a URL.

The URL makes a query for a few features from a map service. A URL querying features from a feature service can also be specified.

}

Attributes for route_renewals

When specifying the route renewals, you can specify additional properties for route renewals, such as the route name or service time, using attributes. The route_renewals parameter can be specified with the following attributes:

• DepotName

  The name of the depot where this renewal takes place. This attribute is a foreign key to the Name attribute in the depots parameter, so the values must match. The attribute cannot have a null value.

• RouteName

  The name of the route that this renewal applies to. This attribute is a foreign key to the Name attribute in the routes parameter, so the values must match. The attribute cannot have a null value.

• ServiceTime

  The service time for the renewal. This attribute can contain a null value; a null value indicates zero service time. The units for this attribute value are specified by the time_units parameter.

  Note:

  The time taken to load a vehicle at a renewal depot may depend on the size of the vehicle and how full or empty the vehicle is. However, the service time for a route renewal is a fixed value and does not take into account the actual load. Assign the renewal service time a value corresponding to a full truckload, an average truckload, or another time estimate of your choice.

• Sequences

  Specifies one or more sequences of visits to the renewal depot. This attribute can be used to preassign visits to the renewal depot. The attribute value is specified as a space-separated string of sequence values. The attribute can contain a null value; a null value indicates that the service will determine the best sequence to visit the renewal depot.

Example for route_renewals

Example: Specify route renewals using a JSON structure

In this example, a distribution company makes deliveries from a central depot using two trucks. Over time, the distribution company also acquired two additional satellite distribution centers. These centers can be used by the trucks to renew their truckload while making their deliveries instead of returning to the main distribution center for renewal. The new distribution centers are specified as route renewals when solving the vehicle routing problem, and the service determines the best renewal locations that minimize the total cost.

You must specify two route renewal locations for each route, so you have a total of four route renewal features. Identify the depot location that can be used for renewal using the DepotName attribute. Specify the name of the route the renewal applies to using the RouteName attribute. Because it takes 15 minutes to load the truck at the renewal location, specify 15 as the value for the ServiceTime attribute assuming the time_units parameter is set to Minutes. The other attribute values are not specified because their default values are adequate in this scenario.

        "ServiceTime": 15
      }
    }
  ]
}

Attributes for order_pairs

When specifying the order pairs, you can specify additional properties for order pairs, such as the orders that should be paired together or the maximum transit time, using attributes. The order_pairs parameter can be specified with the following attributes:

• FirstOrderName—The name of the first order of the pair. This attribute is a foreign key to the Name attribute in the orders parameter, so the values must match. The attribute cannot have a null value.
• SecondOrderName—The name of the second order of the pair. This attribute is a foreign key to the Name attribute in the orders parameter, so the values must match. The attribute cannot have a null value.
• MaxTransitTime

  The maximum transit time for the pair. The transit time is the duration from the departure time of the first order to the arrival time at the second order. This constraint limits the time-on-vehicle, or ride time, between the two orders. When a vehicle is carrying people or perishable goods, the ride time is typically shorter than that of a vehicle carrying packages or nonperishable goods.

  Excess transit time (measured with respect to the direct travel time between order pairs) can be tracked and weighted by the service. Because of this, you can direct the service to take one of three approaches: minimize the overall excess transit time regardless of the increase in travel cost for the fleet, find a solution that balances overall violation time and travel cost, or ignore the overall excess transit time and, instead, minimize the travel cost for the fleet. By assigning an importance level for the excess_transit_factor parameter, you are in effect choosing one of these three approaches. Regardless of the importance level, the service will always return an error if the MaxTransitTime attribute value is surpassed.

  This attribute can contain null values; a null value indicates that there is no constraint on the ride time. The default value for this attribute is null.

In this example, a paratransit company needs to find the best routes for a fleet of vans to transport people who would otherwise not have access to transportation from their homes to various hospitals for medical appointments.

The hospital and patient locations are specified as the orders parameter. The passengers must be taken to a predetermined hospital. For each patient-to-hospital pair, add a feature to the order_pairs parameter using the patient name as the value for the FirstOrderName attribute and the hospital name as the value for the SecondOrderName attribute. The maximum time in minutes that the patients can sit in the van during a one-way trip is specified using the MaxTransitTime attribute.

Attributes for point_barriers

When specifying point barriers, you can set properties for each, such as its name or barrier type, using the following attributes:

Name

The name of the barrier.

BarrierType

Specifies whether the point barrier restricts travel completely or adds time or distance when it is crossed. The value for this attribute is specified as one of the following integers (use the numeric code, not the name in parentheses):

• 0 (Restriction)—Prohibits travel through the barrier. The barrier is referred to as a restriction point barrier since it acts as a restriction.

  

• 2 (Added Cost)—Traveling through the barrier increases the travel time or distance by the amount specified in the Additional_[Cost] attributes. This barrier type is referred to as an added cost point barrier.

  

Additional_Time

The added travel time when the barrier is traversed. This field is applicable only for added-cost barriers and when the measurement_units parameter is time-based

This field value must be greater than or equal to zero, and its units are the same as those specified in the measurement_units parameter.

Additional_Distance

The added distance when the barrier is traversed. This field is applicable only for added-cost barriers and when the measurement_units parameter is distance-based

The field value must be greater than or equal to zero, and its units are the same as those specified in the measurement_units parameter.

AdditionalCost

The added cost when the barrier is traversed. This field is applicable only for added-cost barriers when the impedance attribute is neither time-based nor distance-based.

FullEdge

Specifies how the restriction point barriers are applied to the edge elements during the analysis. The field value is specified as one of the following integers (use the numeric code, not the name in parentheses):

• 0 (False)—Permits travel on the edge up to the barrier but not through it. This is the default value.
• 1 (True)—Restricts travel anywhere on the associated edge.

CurbApproach

Specifies the direction of traffic that is affected by the barrier. The field value is specified as one of the following integers (use the numeric code, not the name in parentheses):

• 0 (Either side of vehicle)—The barrier affects travel over the edge in both directions.
• 1 (Right side of vehicle)—Vehicles are only affected if the barrier is on their right side during the approach. Vehicles that traverse the same edge but approach the barrier on their left side are not affected by the barrier.
• 2 (Left side of vehicle)—Vehicles are only affected if the barrier is on their left side during the approach. Vehicles that traverse the same edge but approach the barrier on their right side are not affected by the barrier.

Because junctions are points and don't have a side, barriers on junctions affect all vehicles regardless of the curb approach.

The CurbApproach attribute works with both types of national driving standards: right-hand traffic (United States) and left-hand traffic (United Kingdom). First, consider a facility on the left side of a vehicle. It is always on the left side regardless of whether the vehicle travels on the left or right half of the road. What may change with national driving standards is your decision to approach a facility from one of two directions, that is, so it ends up on the right or left side of the vehicle. For example, to arrive at a facility and not have a lane of traffic between the vehicle and the facility, choose 1 (Right side of vehicle) in the United States and 2 (Left side of vehicle) in the United Kingdom.

Bearing

The direction in which a point is moving. The units are degrees and are measured clockwise from true north. This field is used in conjunction with the BearingTol field.

Bearing data is usually sent automatically from a mobile device equipped with a GPS receiver. Try to include bearing data if you are loading an input location that is moving, such as a pedestrian or a vehicle.

Using this field tends to prevent adding locations to the wrong edges, which can occur when a vehicle is near an intersection or an overpass, for example. Bearing also helps the tool determine on which side of the street the point is.

Learn more about bearing and bearing tolerance

BearingTol

The bearing tolerance value creates a range of acceptable bearing values when locating moving points on an edge using the Bearing field. If the Bearing field value is within the range of acceptable values that are generated from the bearing tolerance on an edge, the point can be added as a network location there; otherwise, the closest point on the next-nearest edge is evaluated.

The units are in degrees, and the default value is 30. Values must be greater than 0 and less than 180. A value of 30 means that when Network Analyst attempts to add a network location on an edge, a range of acceptable bearing values is generated 15 degrees to either side of the edge (left and right) and in both digitized directions of the edge.

Learn more about bearing and bearing tolerance

NavLatency

This field is only used in the solve process if the Bearing and BearingTol fields also have values; however, entering a NavLatency field value is optional, even when values are present in Bearing and BearingTol. NavLatency indicates how much cost is expected to elapse from the moment GPS information is sent from a moving vehicle to a server and the moment the processed route is received by the vehicle's navigation device.

The units of NavLatency are the same as the units of the impedance attribute.

  Specifies whether the barrier restricts travel completely or scales the cost (such as time or distance) for traveling through it. The field value is specified as one of the following integers (use the numeric code, not the name in parentheses):

  • 0 (Restriction)—Prohibits traveling through any part of the barrier. The barrier is referred to as a restriction polygon barrier since it prohibits traveling on streets intersected by the barrier. One use of this type of barrier is to model floods covering areas of the street that make traveling on those streets impossible.

    This is the default value.

    

  • 1 (Scaled Cost)—Scales the cost (such as travel time or distance) required to travel the underlying streets by a factor specified using the ScaledTimeFactor or ScaledDistanceFactor field. If the streets are partially covered by the barrier, the travel time or distance is apportioned and then scaled. For example, a factor of 0.25 means that travel on underlying streets is expected to be four times faster than normal. A factor of 3.0 means it is expected to take three times longer than normal to travel on underlying streets. This barrier type is referred to as a scaled-cost polygon barrier. It can be used to model storms that reduce travel speeds in specific regions, for example.

    

• ScaledTimeFactor

  This is the factor by which the travel time of the streets intersected by the barrier is multiplied. The field value must be greater than zero.

  This field is applicable only for scaled-cost barriers and when the measurement_units parameter is time-based.

• ScaledDistanceFactor

  This is the factor by which the distance of the streets intersected by the barrier is multiplied. The field value must be greater than zero.

  This field is applicable only for scaled-cost barriers and when the measurement_units parameter is distance-based.

• ScaledCostFactor

  This is the factor by which the cost of the streets intersected by the barrier is multiplied. The field value must be greater than zero.

  This field is applicable only for scaled-cost barriers when the impedance is neither time-based nor distance-based .

Examples for polygon_barriers

Example 1: Specifying polygon barriers using a JSON structure.

The example shows how to add two polygons as barriers. The first polygon named Flood zone is a restriction polygon barrier that prohibits travel on the underlying streets. The polygon is a single-part polygon feature made up of four points. The second polygon named Severe weather zone is a scaled-cost polygon barrier that increases the travel time on underlying streets to one third of the original value. The polygon is a two-part polygon feature. Both parts are made up of four points.

Example 2: Specifying a polygon barrier using a URL

The URL makes a query for a few features from a map service. A URL querying features from a feature service can also be specified.

Example for restrictions

restrictions=[Driving a Truck, Height Restriction, Length Restriction]

Attributes for attribute_parameter_values

The attribute_parameter_values parameter can be specified with the following attributes:

• AttributeName—The name of the restriction.
• ParameterName—The name of the parameter associated with the restriction. A restriction can have one or more ParameterName values based on its intended use, which implies you may need multiple attribute_parameter_values parameters for a single attribute name.
• ParameterValue—The value for the ParameterName that is used by the service when evaluating the restriction.

When specifying the attribute_parameter_values parameter, each restriction (listed as AttributeName) has a ParameterName value, Restriction Usage, that specifies whether the restriction prohibits, avoids, or prefers travel on the roads associated with the restriction and the degree to which the roads are avoided or preferred.

The Restriction Usage value for ParameterName can be any of the following string values or their equivalent numeric values listed within the parentheses:

• Prohibited (-1)—Travel on the roads that have the restriction is prohibited.
• Avoid_High (5)—It is very unlikely the service will include in the route the roads that are associated with the restriction.
• Avoid_Medium (2)—It is unlikely the service will include in the route the roads that are associated with the restriction.
• Avoid_Low (1.3)—It is somewhat unlikely the service will include in the route the roads that are associated with the restriction.
• Prefer_Low (0.8)—It is somewhat likely the service will include in the route the roads that are associated with the restriction.
• Prefer_Medium(0.5)—It is likely the service will include in the route the roads that are associated with the restriction.
• Prefer_High (0.2)—It is very likely the service will include in the route the roads that are associated with the restriction.

The following table lists the restriction names and the default restriction parameter values for all the restrictions. The default value for the attribute_parameter_values parameter is the JSON structure containing all the rows from the below table.

Examples for locate_settings

Example 1: Specify default locate settings using JSON structure

This example shows how to specify locate settings so inputs are only located within 500 meters of the specified location. A small search tolerance like this can be valuable if you are solving using a walking travel mode and don't want inputs to be located farther than 500 meters from the original point location.

{
  "default": {
    "tolerance": 500,
    "toleranceUnits": "esriMeters",
    "allowAutoRelocate": true,
    "sources": [
      {
        "name": "Routing_Streets"
      }
    ]
  }
}

Example 2: Specify default locate settings and locate settings overrides for some inputs using JSON structure

This example shows how to specify locate settings to prevent orders and depots from locating on highway ramps. The default locate settings allow locating on the Routing_Streets source. For orders and depots, the overrides option is used to specify a where clause for the Routing_Streets source to prevent locating on highway ramps (a ROAD_CLASS field value of 3). With this locate_settings json, orders and depots cannot locate on highway ramps, but barriers can because they use the default locate settings, which do not include a where clause.

{
    "default": {
        "tolerance": 20,
        "toleranceUnits": "esriKilometers",
        "allowAutoRelocate": true,
        "sources": [{
            "name": "Routing_Streets"
        }]
    },
    "overrides": {
        "orders": {
            "sources": [{
                "name": "Routing_Streets",
                "where": "ROAD_CLASS <> 3"
            }]
        },
        "depots": {
            "sources": [{
                "name": "Routing_Streets",
                "where": "ROAD_CLASS <> 3"
            }]
        }
    }
}

Example three: Specify default locate settings and locate settings overrides using JSON structure so different inputs are located using different sources.

This example shows how to specify default locate settings to locate inputs on Routing_Streets source feature class while allowing point barriers to only locate on the system junctions feature class (Routing_ND_Junctions).

{
    "default": {
        "tolerance": 20,
        "toleranceUnits": "esriKilometers",
        "allowAutoRelocate": true,
        "sources": [{
            "name": "Routing_Streets"
        }]
    },
    "overrides": {
        "point_barriers": {
            "sources": [{
                "name": "Routing_ND_Junctions"
            }]
        }
    }
}
