Description

Data type

Name

The name of the stop. The name is used in the driving directions. If the name is not specified, a unique name prefixed with Location is automatically generated in the output stops, routes, and directions.

String

RouteName

The name of the route to which the stop is assigned. Assigning the same route name to different stops causes those stops to be grouped together and visited by the same route. You can generate many routes in a single solve by assigning unique route names to different groups of stops. You can group up to 150 stops into one route.

String

Sequence

The output routes will visit the stops in the order you specify with this attribute. Within a group of stops that have the same RouteName value, the sequence number should be greater than 0 but not greater than the total number of stops. Also, the sequence number should not be duplicated.

If Reorder Stops To Find Optimal Routes is checked (True), all but possibly the first and last sequence values for each route name are ignored so the tool can find the sequence that minimizes overall travel for each route. (The settings for Preserve Ordering of Stops and Return to Start determine whether the first or last sequence values for each route are ignored.)

Integer

AdditionalTime

The amount of time spent at the stop, which is added to the total time of the route. The units for this attribute value are specified by the Measurement Units parameter. The attribute value is included in the analysis only when the measurement units are time based. The default value is 0.

You can account for the extra time it takes at the stop to complete a task, such as to repair an appliance, deliver a package, or inspect the premises.

Double

AdditionalDistance

The extra distance traveled at the stops, which is added to the total distance of the route. The units for this attribute value are specified by the Measurement Units parameter. The attribute value is included in the analysis only when the measurement units are distance based. The default value is 0.

Generally, the location of a stop, such as a home, isn't exactly on the streets; it is set back somewhat from the road. This attribute value can be used to model the distance between the actual stop location and its location on the street, if it is important to include that distance in the total travel distance.

TimeWindowStart

The earliest time the stop can be visited. Make sure you specify the value as a date and time value, such as 8/12/2015 12:15 PM. By specifying a start and end time for a stop's time window, you are defining when a route should visit the stop. As long as Use Time Windows is checked and you've chosen a time-based unit for Measurement Units, the tool will try to find a solution that minimizes overall travel and reaches the stop within the prescribed time window.

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

This field can contain a null value; a null value indicates a route can arrive at any time before the time indicated in the TimeWindowEnd attribute. If a null value is also present in TimeWindowEnd, a route can visit the stop at any time.

Date

TimeWindowEnd

The latest time the stop can be visited. Make sure you specify the value as a date and time value, such as 8/12/2015 12:15 PM. By specifying a start and end time for a stop's time window, you are defining when a route should visit the stop. As long as Use Time Windows is checked and you've chosen a time-based unit for Measurement Units, the tool will try to find a solution that minimizes overall travel and reaches the stop within the prescribed time window.

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

This field can contain a null value; a null value indicates a route can arrive at any time after the time indicated in the TimeWindowStart attribute. If a null value is also present in TimeWindowStart, a route can visit the stop at any time.

Date

CurbApproach

Specifies the direction a vehicle may arrive at and depart from the stop. 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 vehicle can approach and depart the stop in either direction, so a U-turn is allowed at the stop. This setting can be chosen if it is possible and practical for your vehicle to turn around at the stop. This decision may depend on the width of the road and the amount of traffic or whether the stop has a parking lot where vehicles can enter and turn around.
• 1 ( Right side of vehicle)—When the vehicle approaches and departs the stop, the stop 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-hand side.
• 2 (Left side of vehicle)—When the vehicle approaches and departs the stop, the curb 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-hand side.
• 3 (No U-Turn)—When the vehicle approaches the stop, the curb can be on either side of the vehicle; however, the vehicle must depart without turning around.

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 stop 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 stop 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 stop and not have a lane of traffic between the vehicle and the stop, you would choose Right side of vehicle (1) in the United States but Left side of vehicle (2) in the United Kingdom.

Integer

LocationType

Specifies the stop type. The field value is specified as one of the following integers (use the numeric code, not the name in the parentheses):

• 0 (Stop)—A location that the route should visit. This is the default.
• 1 (Waypoint)— A location that the route should travel through without making a stop. Waypoints can be used to force the route to take a specific path (to go through the waypoint) without being considered an actual stop. Waypoints do not appear in directions.

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):

• 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_Time or Additional_Distance field. This barrier type is referred to as an added-cost point barrier.

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.

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):

• 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.
• 1 (Scaled Cost)—Scales the time or distance required to travel the underlying streets by a factor specified using the ScaledTimeFactoror 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 0.25 would mean that travel on underlying streets is expected to be four times faster than normal. A factor of 3.0 would mean 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 might be used to model storms that reduce travel speeds in specific regions.

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.
