Orders
Field | Description | Data type |
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. | String |
ServiceTime | This property specifies how much time 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 the network location requires no service time. The unit for this field value is specified by the time_units parameter. | Double |
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 leave before the time window is over, subtract ServiceTime from the TimeWindowEnd1 field. The time window fields can contain a time-only value or a date and time value. If a time field such as TimeWindowStart1 has a time-only value (for example, 8:00 AM), the date is assumed to be the date specified by the Default Date parameter. Using date and time values (for example, 7/11/2010 8:00 AM) allows you to set time windows that span multiple days. 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. | Date |
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. | Date |
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 nonnull, they can't overlap. Also, the second time window must occur after the first. | Date |
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. | Date |
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. On the other hand, 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 Field Units parameter Time window violations can be tracked and weighted by the solver. Because of this, you can direct the VRP solver to take one of three approaches:
By assigning an importance level for the Time Window Violation Importance parameter, you are essentially choosing one of these three approaches. In any case, however, the solver will return an error if the value set for MaxViolationTime1 is surpassed. | Double |
MaxViolationTime2 | The maximum allowable violation time for the second time window of the order. This field is analogous to the MaxViolationTime1 field. | Double |
InboundArriveTime | Defines when the item to be delivered to the order will be ready at the starting depot. 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. 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. Notes:
| Date |
OutboundDepartTime | Defines when the item to be picked up at the order must arrive at the ending depot. 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. 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. Notes:
| Date |
DeliveryQuantities | The size of the delivery. You can specify size in any dimension you want, such as weight, volume, or quantity. You can even 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 instance, 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 need to be in the same units, and if you are using multiple dimensions, the dimensions need to be listed in the same sequence for all parameters. So 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 need to be specified the same way: weight in pounds, then volume in cubic feet. If you mix units or change the sequence, you will get unwanted results without receiving any warning messages. An empty string or null value is equivalent to all dimensions being zero. 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 zeros. Delivery quantities can't be negative. | String |
PickupQuantities | The size of the pickup. You can specify size in any dimension you want, such as weight, volume, or quantity. You can even 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. | String |
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 route class never includes revenue in its output. However, revenue weights the relative importance of servicing orders. | Double |
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 would enter BucketTruck in the SpecialtyNames field for these orders to indicate their special need. SpecialtyNames would be left as null for the other orders. Similarly, the company would also enter BucketTruck in the SpecialtyNames field of routes that are driven by trucks with hydraulic booms. It would leave 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. | String |
AssignmentRule |
This field can't contain a null value. | Integer |
RouteName | The name of the route to which the order is assigned. As an input field, this field is used to preassign an order to a specific route. (A maximum of 200 orders can be preassigned to one route name.) It can contain a null value, indicating that the order is not preassigned to any route, and the solver determines 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. | String |
Sequence | This indicates the sequence of the order on its assigned route. As an input field, this field is used to specify the relative sequence for 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. So the smallest possible output sequence value for a routed order is 2, since a route always begins at a depot | Integer |
CurbApproach | Specifies the direction a vehicle may arrive at and depart from the order. The field value is specified as one of the following integers shown in the parentheses (use the numeric code, not the name in parentheses):
The CurbApproach property 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, you would choose 1 (Right side of vehicle) in the United States but 2 (Left side of vehicle) in the United Kingdom. | Short Integer |
Depots
Field | Description | Data type |
Name | The name of the depot. The StartDepotName and EndDepotName fields of the Routes record set reference the names you specify here. It is also referenced by the Route Renewals record set, when used. Depot names are case insensitive and have to be nonempty and unique. | String |
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. Time window fields can contain a time-only value or a date and time value. If a time field has a time-only value (for example, 8:00 AM), the date is assumed to be the date specified by the Default Date parameter of the analysis layer. Using date and time values (for example, 7/11/2010 8:00 AM) allows you to set time windows that span multiple days. 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. | Date |
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. | Date |
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 nonnull, they can't overlap. Also, the second time window must occur after the first. | Date |
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. | Date |
CurbApproach | Specifies the direction a vehicle may arrive at and depart from the depot. The field value is specified as one of the following integers shown in the parentheses (use the numeric code, not the name in parentheses):
The CurbApproach property 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, you would choose 1 (Right side of vehicle) in the United States but 2 (Left side of vehicle) in the United Kingdom. | Integer |
Bearing | The direction in which a point is moving. The units are degrees and measured in a clockwise fashion 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 order 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. For more information, see the Bearing and Bearing Tolerance Help topic (https://links.esri.com/bearing-and-bearing-tolerance). | Double |
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 value from the Bearing field 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 zero 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. For more information, see the Bearing and Bearing Tolerance topic in the ArcGIS help system (https://links.esri.com/bearing-and-bearing-tolerance). | Double |
NavLatency | This field is only used in the solve process if Bearing and BearingTol also have values; however, entering a NavLatency value is optional, even when values are present in Bearing and BearingTol. NavLatency indicates how much time 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 time units of NavLatency are the same as the units of the cost attribute specified by the parameter Time Attribute. | Double |
Routes
Field | Description | Data type |
Name | The name of the route. The name must be unique. The tool generates a unique name at solve time if the field value is null; therefore, entering a value is optional in most cases. However, you must enter a name if your 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. Note that route names are case insensitive. | String |
StartDepotName | The name of the starting depot for the route. This field is a foreign key to the Name field in Depots. 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 your 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 class) 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. | String |
EndDepotName | The name of the ending depot for the route. This field is a foreign key to the Name field in the Depots class. | String |
StartDepotServiceTime | The service time at the starting depot. This can be used to model the time spent loading the vehicle. This field can contain a null value; a null value indicates zero service time. The unit for this field value is specified by the Time Field Units parameter. The service times at the start and end depots are fixed values (given by the StartDepotServiceTime and EndDepotServiceTime field 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. As such, the depot service times could be given values corresponding to a full truckload or an average truckload, or you could make your own time estimate. | Double |
EndDepotServiceTime | The service time at the ending depot. This can be used to model the time spent unloading the vehicle. This field can contain a null value; a null value indicates zero service time. The unit for this field value is specified by the Time Field Units parameter. The service times at the start and end depots are fixed values (given by the StartDepotServiceTime and EndDepotServiceTime field 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. As such, the depot service times could be given values corresponding to a full truckload or an average truckload, or you could make your own time estimate. | Double |
EarliestStartTime | The earliest allowable starting time for the route. This is used by the solver in conjunction with the time window of the starting depot for determining feasible route start times. This field can't contain null values and has a default time-only value of 8:00 AM; the default value is interpreted as 8:00 a.m. on the date given by the Default Date parameter. When solving a problem that spans multiple time zones, the time zone for EarliestStartTime is the same as the time zone in which the starting depot is located. | Date |
LatestStartTime | The latest allowable starting time for the route. This field 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 given by the Default Date property of the analysis layer. When solving a problem that spans multiple time zones, the time zone for LatestStartTime is the same as the time zone in which the starting depot is located. | Date |
ArriveDepartDelay | This field 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 VRP solver is deterred from sending many routes to service physically coincident orders. The cost for this property 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 since 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 afterwards, the VRP solver 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. To illustrate, assume there are five coincident orders in a high-rise building, and they are serviced by three different 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 instead, only one driver would need to park and enter the building—only one arrive/depart delay would be incurred. Since the VRP solver tries to minimize cost, it will try to limit the arrive/depart delays and thus choose the single-route option. (Note that multiple routes may need to be sent when other constraints—such as specialties, time windows, or capacities—require it.) The unit for this field value is specified by the time_units parameter. | Double |
Capacities | The maximum capacity of the vehicle. You can specify capacity in any dimension you want, such as weight, volume, or quantity. You can even specify multiple dimensions, for example, weight and volume. Enter capacities without indicating units. For example, assume your vehicle can carry a maximum of 40,000 pounds; you would enter 40000. 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 instance, if you are recording both weight and volume and your vehicle can carry a maximum weight of 40,000 pounds and a maximum volume of 2,000 cubic feet, Capacities should be entered as 40000 2000. Again, you need to remember the units. You also need to remember the sequence in which the values and their corresponding units are entered (pounds followed by cubic feet in this case). Remembering the units and the unit sequence is important for a couple of reasons: one, so you can reinterpret the information later; two, so you can properly enter values for the DeliveryQuantities and PickupQuantities fields for the orders. To elaborate on the second point, note that the VRP solver simultaneously refers to Capacities, DeliveryQuantities, and PickupQuantities to make sure that a route doesn't become overloaded. Since units can't be entered in the field, the VRP tool can't make unit conversions, so you need to enter the values for the three fields using the same units and the same unit sequence to ensure the values are correctly interpreted. If you mix units or change the sequence in any of the three fields, you will get unwanted results without receiving any warning messages. Thus, it is a good idea to set up a unit and unit-sequence standard beforehand and continually refer to it whenever entering values for these three fields. 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 fields for orders, the remaining values are treated as zero. The VRP solver 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, the VRP solver will assume the cargo fits in the vehicle. This could be incorrect, depending on the actual shape of the cargo and the vehicle. For example, the VRP solver 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. | String |
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 field can contain null values; a null value indicates zero fixed cost. This cost is part of the total route operating cost. | Double |
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 field can't contain a null value and has a default value of 1.0. The unit for this field value is specified by the time_units parameter. | Double |
CostPerUnitDistance | The monetary cost incurred—per unit of distance traveled—for the route length (total travel distance). This field can contain null values; a null value indicates zero cost. The unit for this field value is specified by the distance_units parameter. | Double |
OvertimeStartTime | The duration of regular work time before overtime computation begins. This field can contain null values; a null value indicates that overtime does not apply. The unit for this field 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. | Double |
CostPerUnitOvertime | The monetary cost incurred per time unit of overtime work. This field can contain null values; a null value indicates that the CostPerUnitOvertime value is the same as the CostPerUnitTime value. | Double |
MaxOrderCount | The maximum allowable number of orders on the route. This field can't contain null values and has a default value of 30. This value cannot exceed 200. | Integer |
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 field can contain null values; a null value indicates that there is no constraint on the route duration. The unit for this field value is specified by the time_units parameter. | Double |
MaxTotalTravelTime | The maximum allowable travel time for the route. The travel time includes only the time spent driving on the network and does not include service or wait times. This field can contain null values; a null value indicates there is no constraint on the maximum allowable travel time. This field value can't be larger than the MaxTotalTime field value. The unit for this field value is specified by the time_units parameter. | Double |
MaxTotalDistance | The maximum allowable travel distance for the route. The unit for this field value is specified by the distance_units parameter. This field can contain null values; a null value indicates that there is no constraint on the maximum allowable travel distance. | Double |
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 field is a foreign key to the SpecialtyNames field in the orders class. 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 would enter BucketTruck in the SpecialtyNames field for these orders to indicate their special need. SpecialtyNames would be left as null for the other orders. Similarly, the company would also enter BucketTruck in the SpecialtyNames field of routes that are driven by trucks with hydraulic booms. It would leave 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. | String |
AssignmentRule | This specifies whether the route can be used or not when solving the problem. This field is constrained by a domain of values, which are listed below (use the numeric code, not the name in parentheses).
| Integer |
Breaks
Field | Description | Data type |
RouteName | The name of the route to which the break applies. Although a break is assigned to exactly one route, many breaks can be assigned to the same route. This field is a foreign key to the Name field in the routes parameter, so it can't have a null value. | String |
Precedence | Precedence values 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. | Integer |
ServiceTime | The duration of the break. This field can't contain null values. The default value is 60. The unit for this field value is specified by the time_units parameter. | Double |
TimeWindowStart | The starting time of the break's time window. If this field is null and TimeWindowEnd has a valid time-of-day value, the break is allowed to start any time before the TimeWindowEnd value. If this field has a value, the MaxTravelTimeBetweenBreaks and MaxCumulWorkTime field values must be null; moreover, all other breaks in the analysis layer must have null values for MaxTravelTimeBetweenBreaks and MaxCumulWorkTime. An error will occur at solve time if a route has multiple breaks with overlapping time windows. The time window fields in breaks can contain a time-only value or a date and time value. If a time field, such as TimeWindowStart, has a time-only value (for example, 12:00 PM), the date is assumed to be the date specified by the default_date parameter. Using date and time values (for example, 7/11/2012 12:00 PM) allows you to specify time windows that span two or more days. This is especially beneficial when a break should be taken sometime before and after midnight. When solving a problem that spans multiple time zones, each break's time-window values refer to the time zone in which the associated route, as specified by the RouteName field, is located. | Date |
TimeWindowEnd | The ending time of the break's time window. If this field is null and TimeWindowStart has a valid time-of-day value, the break is allowed to start any time after the TimeWindowStart value. If this field has a value, MaxTravelTimeBetweenBreaks and MaxCumulWorkTime must be null; moreover, all other breaks in the analysis layer must have null values for MaxTravelTimeBetweenBreaks and MaxCumulWorkTime. | Date |
MaxViolationTime | This field specifies the maximum allowable violation time for a time-window break. A time window is considered violated if the arrival time falls outside the time range. A zero value indicates 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 as per the Time Window Violation Importance parameter. This property can be null; a null value with TimeWindowStart and TimeWindowEnd values indicates that there is no limit on the allowable violation time. If MaxTravelTimeBetweenBreaks or MaxCumulWorkTime has a value, MaxViolationTime must be null. The unit for this field value is specified by the time_units parameter. | Double |
MaxTravelTimeBetweenBreaks | The maximum amount of travel time that can be accumulated before the break is taken. 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, MaxTravelTimeBetweenBreaks also indicates the maximum travel time that can be accumulated from the final break to the end depot. This field is designed to limit how long a person can drive until a break is required. For instance, if the Time Field Units parameter (time_units for Python) of the analysis 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 property should be 120. If this field has a value, TimeWindowStart, TimeWindowEnd, MaxViolationTime, and MaxCumulWorkTime must be null for an analysis to solve successfully. The unit for this field value is specified by the time_units parameter. | Double |
MaxCumulWorkTime | The maximum amount of work time that can be accumulated before the break is taken. 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. Note, however, that 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. This field is designed to limit how long a person can work until a break is required. For instance, if the time_units parameter is set to Minutes, MaxCumulWorkTime has a value of 120, and ServiceTime has a value of 15, the driver will get a 15-minute break after two hours of work. Continuing with the last example, assume a second break is needed after three more hours of work. To specify this break, you would enter 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. If this field has a value, TimeWindowStart, TimeWindowEnd, MaxViolationTime, and MaxTravelTimeBetweenBreaks must be null for an analysis to solve successfully. The unit for this field value is specified by the time_units parameter. | Double |
IsPaid | A Boolean value indicating whether the break is paid or unpaid. A True value indicates that the time spent at the break is included in the route cost computation and overtime determination. A False value indicates otherwise. The default value is True. | Integer |
Sequence | As an input field, this indicates the sequence of the break on its route. This field can contain null values. The input sequence values are positive and unique for each route (shared across renewal depot visits, orders, and breaks) but need not start from 1 or be contiguous. The solver modifies the sequence field. After solving, this field contains the sequence value of the break on its 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. | Integer |
Point Barriers
Field | Description | Data type |
Name | The name of the barrier. | String |
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):
| Short |
Additional_Time | Indicates how much travel time is added when the barrier is traversed. This field is applicable only for added-cost barriers and only if the measurement units are 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. | Double |
Additional_Distance | Indicates how much distance is added when the barrier is traversed. This field is applicable only for added-cost barriers and only if the measurement units are 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. | Double |

Field | Description | Data type |
Name | The name of the barrier. | String |
Polygon Barriers
Field | Description | Data type |
Name | The name of the barrier. | String |
BarrierType | Specifies whether the barrier restricts travel completely or scales the 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):
| Short |
ScaledTimeFactor | This is the factor by which the travel time of the streets intersected by the barrier is multiplied. This field is applicable only for scaled-cost barriers and only if the measurement units are time based. The field value must be greater than zero. | Double |
ScaledDistanceFactor | This is the factor by which the distance of the streets intersected by the barrier is multiplied. This attribute is applicable only for scaled-cost barriers and only if the measurement units are distance based. The attribute value must be greater than zero. | Double |
