Attributes for input locations

• ObjectIDinteger (non-negative)nullable

  The object ID of the input. ObjectID is a unique identifier for each input. If the ObjectID is not specified, a unique ID is automatically generated in the output.

• SourceIDinteger (non-negative)nullable

  The numeric identifier of the network dataset source feature class on which the input point is located.

• SourceOIDinteger (non-negative)nullable

  The object ID of the feature in the source on which the input point is located.

• PosAlongnumber (non-negative)nullable

  The position along the digitized direction of the source line feature. This value is stored as a ratio. This attribute is null if the network location references a junction.

• SideOfEdgeint enumnullable

  Allowed values: 1, 2

  The side of the edge in relation to the digitized direction of the line feature.

  This attribute is limited to a domain of two values:

  • 1: Right Side
  • 2: Left Side

• CurbApproachint enumdefault:0

  Allowed values: 0, 1, 2, 3

  Specifies the direction a vehicle may arrive at and depart from the input location. The field value is specified as one of the following integers:

  • 0: Either side of vehicle. The vehicle can approach and depart the input location in either direction. U-turns are allowed. You should choose this setting if your vehicle can make a U-turn at the order or if it can pull into a driveway or parking lot and turn around.
  • 1: Right side of vehicle. When the vehicle approaches and departs the input location, the curb must be on the right side of the vehicle. A U-turn is prohibited.
  • 2: Left side of vehicle. When the vehicle approaches and departs the input location, the curb must be on the left side of the vehicle. A U-turn is prohibited.
  • 3: No U-turn. When the vehicle approaches the input location, the curb can be on either side of the vehicle; however, the vehicle must depart without turning around. Learn more about U-turn policies

  Setting	Coded value	Description
  Either side of vehicle	0	The vehicle can approach and depart the input location in either direction, so a U-turn is allowed at the input location. This setting can be chosen if it is possible and desirable for a vehicle to turn around at the input location. This decision may depend on the width of the road and the amount of traffic or whether the location has a parking lot where vehicles can pull in and turn around. All arrival and departure combinations are allowed with the Either side of vehicle curb approach.
  Right side of vehicle	1	When the vehicle approaches and departs the input location, the input location 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. The allowed arrival and departure combination for the Right side of vehicle curb approach is shown.
  Left side of vehicle	2	When the vehicle approaches and departs the input location, the input location 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. The allowed arrival and departure combination for the Left side of vehicle curb approach is shown.
  No U-Turn	3	When the vehicle approaches the input location, the input location 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 allowed arrival and departure combinations for the No U-Turn curb approach are shown.

  The CurbApproach attribute is designed to work with both types of national driving standards: right-hand traffic (United States) and left-hand traffic (United Kingdom). First, consider an input location 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 input location 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 input location and not have a lane of traffic between the vehicle and the incident, choose 1 (Right side of vehicle) in the United States and 2 (Left side of vehicle) in the United Kingdom.

  

  

• Bearingnumber (non-negative)nullable

  The direction in which a point is moving. The units are degrees and are measured clockwise from true north.

  This attribute is used in conjunction with the BearingTol attribute. 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 attribute 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 solver determine the side of the street that the point is on.

• BearingTolnumber (range: 0 - 180)default:30nullable

  The bearing tolerance value creates a range of acceptable bearing values when locating moving points on an edge using the Bearing attribute.

  If the Bearing attribute 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. 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

• NavLatencynumber (non-negative)nullable

  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.

  This attribute is only used in the solve process if the Bearing and BearingTol fields also have values; however, providing a NavLatency attribute value is optional, even when values are present in the Bearing and BearingTol.

Attributes for barriers

• Namestringnullable

  The name of the barrier.

• SourceIDinteger (non-negative)nullable

  The numeric identifier of the network dataset source feature class on which the input point is located.

• SourceOIDinteger (non-negative)nullable

  The object ID of the feature in the source on which the input point is located.

• PosAlongnumber (non-negative)nullable

  The position along the digitized direction of the source line feature. This value is stored as a ratio. This attribute is null if the network location references a junction.

• SideOfEdgeint enum

  Allowed values: 1, 2

  The side of the edge in relation to the digitized direction of the line feature.

  This attribute is limited to a domain of two values:

  • 1: Right Side
  • 2: Left Side

• BarrierTypeint enumdefault:0

  Allowed values: 0, 2

  Specify 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:

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

    

    The first map shows the shortest path between two stops without any restriction point barriers. The second map has a road that is blocked by a fallen tree, so the shortest path between the same points is longer.

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

  The map on the left shows the shortest path between two stops without any added cost point barrier. For the map on the right, the travel time from stop one to stop two would be the same whether going around the north end of the block or the south end; however, since crossing railroad tracks incurs a time penalty (modeled with added cost point barriers), the route with only one railroad crossing is chosen. The cost of crossing the barrier is added to the accumulated travel time of the resulting route.

• FullEdgeint enumdefault:0

  Allowed values: 0, 1

  Specify how the restriction point barriers are applied to the edge elements during the analysis

  • 0:False—Permits travel on the edge up to the barrier but not through it.
  • 1:True—Restricts travel anywhere on the associated edge.

• Attr_[Cost]number (non-negative)default:0

  Indicates how the cost (time or distance) is added when the barrier is traversed. This attribute is applicable only for added cost point barriers. The attribute value must be greater than or equal to zero.

Attributes for polylineBarriers

• Namestring (length: 500)nullable

  The name of the barrier.

• ObjectIDinteger (non-negative)nullable

  The object ID of the line barrier. ObjectID is a unique identifier for the line barrier. If you want to maintain a relationship between the input and output, set preserveObjectID to true. The ObjectID value of the input line barrier is included in the output line barrier (as the ObjectID field) and can be used to join additional information from analysis outputs to the attribute of the line barriers. If the ObjectID value is not specified, a unique ID is automatically generated in the output.

• SourceIDinteger (non-negative)nullable

  The numeric identifier of the network dataset source feature class on which the input point is located.

• SourceOIDinteger (non-negative)nullable

  The object ID of the feature in the source on which the input point is located.

• PosAlongnumber (non-negative)nullable

  The position along the digitized direction of the source line feature. This value is stored as a ratio. This attribute is null if the network location references a junction.

• SideOfEdgeint enum

  Allowed values: 1, 2

  The side of the edge in relation to the digitized direction of the line feature.

  This attribute is limited to a domain of two values:

  • 1: Right Side
  • 2: Left Side

• BarrierTypeint enumdefault:0

  Allowed values: 0, 1

  Specify 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:

  • 0: Restriction. Prohibits travel through the barrier. The barrier is referred to as a restriction line barrier since it acts as a restriction.
  • 1: Scaled Cost. Scales the time or distance required to travel the underlying streets by a factor specified using the Attr_[Cost] attribute.

• Attr_[Cost]number (non-negative)default:0

  This attribute is specific to scaled-cost barriers. It is the factor by which the cost of edges underlying the barrier are multiplied.

This example shows how to add two lines as polyline barriers to restrict travel on the streets intersected by the lines. Barrier 1 is a single-part line feature composed of two points. Barrier 2 is a two-part line feature. The first part is composed of three points, and the second part is composed of two points.

Attributes for polygonBarriers

• Namestringnullable

  The name of the barrier.

• ObjectIDinteger (non-negative)nullable

  The object ID of the polygon barrier. ObjectID is a unique identifier for the polygon barrier. If you want to maintain a relationship between the input and output, set preserveObjectID to true. The ObjectID value of the input polygon barrier is included in the output polygon barrier (as the ObjectID field) and can be used to join additional information from analysis outputs to the attribute of the polygon barriers. If the ObjectID value is not specified, a unique ID is automatically generated in the output.

• SourceIDinteger (non-negative)nullable

  The numeric identifier of the network dataset source feature class on which the input point is located.

• SourceOIDinteger (non-negative)nullable

  The object ID of the feature in the source on which the input point is located.

• PosAlongnumber (non-negative)nullable

  The position along the digitized direction of the source line feature. This value is stored as a ratio. This attribute is null if the network location references a junction.

• SideOfEdgeint enum

  Allowed values: 1, 2

  The side of the edge in relation to the digitized direction of the line feature.

  This attribute is limited to a domain of two values:

  • 1: Right Side
  • 2: Left Side

• BarrierTypeint enumdefault:0

  Allowed values: 0, 1

  Specify polygons that either completely restrict travel or proportionately scale the time or distance required to travel on the streets intersected by the polygons.

  The value for this attribute can be specified as one of the following integers:

  • 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.

    

    The first map depicts the shortest path between two stops. The second map shows a polygon barrier blocking flooded streets, so the shortest path between the same two stops is different.

  • 1: Scaled Cost. Scales the cost (such as travel time or distance) required to travel the underlying streets by a factor specified using the Attr_[Cost] attributes.

    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.

  

  The first map shows a route that goes through inclement weather without regard for the effect that poor road conditions have on travel time. The second map shows a scaled polygon barrier that doubles the travel time of the roads covered by the storm. The route still passes through the southern tip of the storm since it is quicker to spend more time driving slowly through a small part of the storm rather than driving completely around it. The service uses the modified travel time in calculating the best route, and the modified travel time is reported as the total travel time in the response.

• Attr_[Cost]number (non-negative)default:0

  This is the factor by which the cost of the streets intersected by the barrier is multiplied. This attribute is applicable only for scaled cost barriers. The attribute value must be greater than zero.

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