GET  https://logistics.arcgis.com/arcgis/rest/services/World/ServiceAreas/GPServer/GenerateServiceAreas/submitJob

The /GenerateServiceAreas job request finds the area that can be reached from the input location within a given travel time or travel distance. A service area is the area that encompasses all streets that can be accessed within a given distance or travel time from one or more locations, referred to as facilities. Service areas are generally used to visualize and measure the accessibility of facilities.

facilities

Specify the input locations around which service areas are generated.

When specifying the facilities, you can set attributes for each as follows:

Show attributes for facilities

Attributes for facilities

  • Namestring (length: 500)nullable

    The name of the facility. If the name is not specified, a name is automatically generated at solve time.

    All fields from the input facilities are included in the output polygons when the polygons_for_multiple_facilities parameter is set to Overlapping or Not Overlapping. The ObjectID field on the input facilities is transferred to the FacilityOID field on the output polygons.

  • Breaksstring (length: 128)

    Specify the extent of the service area to be calculated on a per facility basis.

    This attribute allows you to specify a different service area break value for each facility. For example, with two facilities, you can generate 5- and 10-minute service area polygons for one facility and 6-, 9-, and 12-minute polygons for the other facility.

    Separate multiple break values with a space, and specify the numeric values using the dot character as your decimal separator, even if the locale of your computer defines a different decimal separator. For example, the value 5.5 10 15.5 specifies three break values around a facility.

  • AdditionalTimenumber (non-negative)default:0

    The amount of time spent at the facility, which reduces the extent of the service area calculated for the given facility.

    For example, when calculating service areas that represent fire station response times, AdditionalTime can store the turnout time, which is the time it takes a crew to put on the appropriate protective equipment and exit the fire station, for each fire station. Assume Fire Station 1 has a turnout time of 1 minute and Fire Station 2 has a turnout time of 3 minutes. If a 5-minute service area is calculated for both fire stations, the actual service area for Fire Station 1 is 4 minutes (since 1 of the 5 minutes is required as turnout time). Similarly, Fire Station 2 has a service area of only 2 minutes from the fire station.

  • AdditionalDistancenumber (non-negative)default:0

    The extra distance traveled to reach the facility before the service is calculated. This attribute reduces the extent of the service area calculated for the given facility.

    Generally, the location of a facility, such as a store location, isn't exactly on the street; it is set back somewhat from the road. This attribute value can be used to model the distance between the actual facility location and its location on the street if it is important to include that distance when calculating the service areas for the facility.

  • AdditionalCostnumber (non-negative)default:0

    The extra cost spent at the facility, which reduces the extent of the service area calculated for the given facility. The default value is 0.

    Use this attribute value when the travel mode for the analysis uses an impedance attribute that is neither time based nor distance based The units for the attribute values are interpreted to be in unknown units.

  • CurbApproachint enumdefault:0

    Allowed values: 0, 1, 2, 3

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

    • 0: Either side of vehicle. The vehicle can approach and depart the facility 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 facility, 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 facility, 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 facility, the curb can be on either side of the vehicle; however, the vehicle must depart without turning around. Learn more about U-turn policies
    Show illustration
    SettingCoded valueDescription

    Either side of vehicle

    0

    The vehicle can approach and depart the facility in either direction, so a U-turn is allowed at the facility. This setting can be chosen if it is possible and desirable for a vehicle to turn around at the facility. 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.

    Either side of vehicle

    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 facility, the facility 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.

    Right side of vehicle

    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 facility, the facility 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.

    Left side of vehicle

    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 facility, the facility 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.

    No U-turns

    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 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 an facility 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 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.

     Right side of vehicle with right-hand traffic

    With right-hand traffic, the curb approach that leaves the vehicle closest to the facility is Right side of vehicle.

     Left side of vehicle with left-hand traffic

    With left-hand traffic, the curb approach that leaves the vehicle closest to the facility is Left side of vehicle.

  • 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.

    Learn more about bearing and bearing tolerance

  • 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.

The example shows how to specify some attributes for the facilities.

Example for locate_settings

Example 1: Specify locate settings using a 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 helpful 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.

break_values

Specify the size and number of service areas to generate for each facility. The service generates time-based or distance-based service areas depending on the units for this parameter. If units are time-based, the service areas are generated based on travel time along underlying streets. If units are distance-based, the service areas are generated based on travel distances.

The parameter value is specified as a space separated list of doubles. The units are determined by the break_units parameter.

Multiple area breaks can be specified to create concentric service areas per facility. For instance, to find 2-, 3-, and 5-mile service areas for each facility, specify break_values=2 3 5, separating the values with a space, and set break_units to Miles.

break_units

Allowed values: Meters, Kilometers, Feet, Yards, NauticalMiles, Seconds, Minutes, Hours, Days

Specify the units for the break_values parameter.

travel_direction

Specify whether the direction of travel used to generate the service area polygons is toward or away from the facilities.

This parameter is specified using the following values:

  • Away from Facility—The service area is generated in the direction away from the facilities.
  • Towards Facility—The service area is generated in the direction toward the facilities.

The direction of travel may change the shape of the polygons because impedances on opposite sides of streets may differ or one-way restrictions may exist, such as one-way streets. The direction you should choose depends on the nature of your service area analysis. The service area for a pizza delivery store, for example, should be created away from the facility, whereas the service area of a hospital should be created toward the facility.

analysis_region

Allowed values: Europe, Japan, Korea, MiddleEast MiddleEastAndAfrica, NorthAmerica, SouthAmerica, SouthAsia, Thailand

Specify the region in which to perform the analysis. If a value is not specified for this parameter, the service will automatically calculate the region name based on the location of the input points. Setting the name of the region is recommended to speed up the analysis.

The data coverage page lists the countries that are grouped into each of these regions.

time_of_day

Specify the time and date to depart from or arrive at facilities. This parameter is ignored when break_units is set to distance units.

To use traffic in the analysis, set break_units to a time-based unit, and assign a value to time_of_day. The time_of_day value represents the time at which travel begins, or departs, from the input points. The time is specified as Unix time (milliseconds since midnight, January 1, 1970).

The interpretation of the parameter value depends on whether travel is toward or away from the facilities as specified by the travel_direction parameter.

  • It represents the departure time if travel_direction is set to Away From Facility. This is the default.
  • It represents the arrival time if travel_direction set to Towards Facility.

If a time of day is not passed in, the service uses static road speeds based on average historical speeds or posted speed limits. It uses posted speeds in areas where historical traffic information isn't available.

If the time_Of_day specified is within 4 hours of the current time, live traffic will be used where available. Live traffic retrieves speeds based on phone probe records, sensors, and other data sources and reflects the current travel speeds and predicts speeds for the near future. If the time_Of_day specified is earlier than 4 hours or later than 4 hours from the current time, or the road does not have live traffic, typical traffic speeds will be used. Typical speeds are based on historical traffic patterns. The travel time data is aggregated in 15 minute intervals per day of week based on multiple years worth of data. So a road may have a different travel time at Monday at 8 am, Monday at 8:15 am, or Tuesday at 8 am. Since the variance is just at the day of week and time of day, the travel time is the same on a road for any Monday at 8 am, regardless of the month or year.

If your goal is to model typical travel conditions and avoid large variances from the average due to live traffic, it is recommended to use a date from the past to ensure it doesn't coincide with the 4 hour window from the current time. As an extreme example, you can even use dates from 1990.

The Data Coverage page shows the countries Esri currently provides traffic data for.

The service support two kinds of traffic: live and typical.

Typical traffic

To ensure the task uses typical traffic in locations where it is available, choose a time and day of the week, and then convert the day of the week to one of the following dates from 1990:

  • Monday—1/1/1990
  • Tuesday—1/2/1990
  • Wednesday—1/3/1990
  • Thursday—1/4/1990
  • Friday—1/5/1990
  • Saturday—1/6/1990
  • Sunday—1/7/1990

Set the time and date as Unix time in milliseconds. For example, to solve for 1:03 p.m. on Thursdays, set the time and date to 1:03 p.m., January 4, 1990; and convert to milliseconds (631458180000). Although the dates representing days of the week are from 1990, typical traffic is calculated from recent traffic trends—usually over the last two years worth of data.

Live traffic

To use live traffic when and where it is available, choose a time and date and convert to Unix time.

Esri saves live traffic data for 4 hours and references predictive data extending 4 hours into the future. If the time and date you specify for this parameter is outside the 8-hour time window, or the travel time in the analysis continues past the predictive data window, the task falls back to typical traffic speeds.

time_zone_for_time_of_day

Allowed values: Geographically Local, UTC

Specify the time zone or zones of the time_Of_day parameter.

  • Geographically Local—The time_Of_day value refers to the time zone or zones in which the input points are located. This option causes the analysis to have rolling start times across time zones.

    Illustration of setting the value to Geographically Local

    Setting time_of_day to 9:00 a.m., January 4, 1990 (631443600000 milliseconds); time_zone_for_time_Of_Day to Geographically Local; and submitting a valid request causes the drive times for points in the eastern time zone to start at 9:00 a.m. eastern Time and 9:00 a.m. central time for points in the central time zone. (The start times are offset by an hour in real or UTC time.)

    Time zone for time of day parameter is set to geographically local
    Input: time_Of_day is 9:00 a.m., January 4, 1990 (631443600000 milliseconds), and time_zone_for_time_Of_day is set to Geographically Local
  • UTC—The time_Of_day value refers to coordinated universal time (UTC). The start times for all points are simultaneous, regardless of time zones.

    Illustration of setting the value to UTC

    Setting time_Of_day to 9:00 a.m., January 4, 1990 (631443600000 milliseconds); time_zone_for_time_Of_Day to UTC, the start times for points in the eastern time zone is 4:00 a.m. Eastern Time and 3:00 a.m. central time for those in the central time zone.

uturn_at_junctions

Allowed values: Allowed, Allowed only at Intersections and Dead Ends, Allowed only at Dead Ends, Not Allowed

Specify whether to restrict or permit the route from making U-turns at junctions.

To understand the available parameter values, a junction is a point where only two streets intersect each other. If three or more streets intersect at a point, it is called as an intersection. A cul-de-sac is a dead-end.

Expand to learn more about the available parameter values

This parameter can have the following values:

Parameter ValueDescription

Allowed

U-turns are permitted everywhere. Permitting U-turns implies that the vehicle can turn around at a junction and double back on the same street.

U-turns permitted

U-turns are permitted at junctions with any number of adjacent streets.

Allowed only at Intersections and Dead Ends

U-turns are prohibited at junctions where exactly two adjacent streets meet.

U-turns permitted only at intersections and dead-ends

U-turns are permitted only at intersections or dead ends.

Allowed only at Dead Ends

U-turns are prohibited at all junctions and intersections and are permitted only at dead ends.

U-turns permitted only at dead-ends

U-turns are permitted only at dead ends.

Not Allowed

U-turns are prohibited at all junctions, intersections, and dead-ends. Even when this parameter value is chosen, a route can still make U-turns at stops. To prohibit U-turns at a stop, you can set its CurbApproach property to the appropriate value (3).

polygons_for_multiple_facilities

Allowed values: Overlapping, Not Overlapping, Merge by Break Value

Specify how to generate service areas when multiple facilities are present. The parameter is specified using one of the following values:

  • Overlapping—Create individual service areas for each facility. The service areas from different facilities can overlap each other.
  • Not Overlapping—Create individual service areas for each facility such that a service area from one facility cannot overlap service areas from other facilities. With this option, the area inside any given service area is closer to the corresponding facility than any other facility.
  • Merge by Break Value—Join the service areas of different facilities that have the same break value. Unlike the Overlapping and Not Overlapping options, this option does not result in individual service areas for each facility.

polygon_overlap_type

Allowed values: Rings, Disks

Specify whether multiple service areas around a facility are created as disks or rings. The parameter is specified using one of the following values:

  • Rings—When creating multiple service areas around a facility, do not include the region covered by the smaller service area into the region covered by the larger service area. Use this option if you want to find the area from one break to another. For instance, If you create 5- and 10-minute service areas, the 10-minute service areas will exclude the area under the 5-minute service areas and thus would appear like rings.
  • Disks—When creating multiple service areas around a facility, creates service areas going from the facility to the break. For instance, If you create 5- and 10-minute service areas, the 10-minute service area will include the area under the 5-minute service area.

detailed_polygons

Specify the whether to create detailed or generalized service areas.

polygon_trim_distance

Allowed values: esriCentimeters, esriDecimalDegrees, esriDecimeters, esriFeet, esriInches, esriKilometers, esriMeters, esriMiles, esriMillimeters, esriNauticalMiles, esriPoints, esriNAUYards

Specify the distance within which the service areas are trimmed. This is useful when finding service areas in places that have very sparse street networks and you don't want the service area to cover large areas where there are no street features.

The parameter is specified as a JSON structure that includes the following properties:

  • distance—The trim distance value. A 0 (zero) distance value specifies that the service areas should not be trimmed.
  • units—The units for the trim distance value.

The parameter value is ignored when the use_hierarchy parameter is set to true.

Allowed values: esriCentimeters, esriDecimalDegrees, esriDecimeters, esriFeet, esriInches, esriKilometers, esriMeters, esriMiles, esriMillimeters, esriNauticalMiles, esriPoints, esriNAUYards

Specify by how much you want to simplify the service area geometry returned by the service.

Simplification maintains critical points of an area to define its essential shape and removes other points. The simplification distance you specify is the maximum allowable offset that the simplified area can deviate from the original area. Simplifying an area reduces the number of points that are used to construct the area and tends to reduce drawing times.

The parameter is specified as a JSON structure that includes the following properties:

  • distance—The simplification distance value.
  • units—The units for the simplification distance value.

point_barriers

Specify one or more points that will act as temporary restrictions or represent additional time or distance that may be required to travel on the underlying streets. For example, a point barrier can be used to represent a fallen tree along a street or a time delay spent at a railroad crossing.

When specifying point barriers, you can set properties for each, such as its name or barrier type.

    • 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: 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.

  • 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.

      Two maps demonstrate how a restriction point barrier affects a route analysis.

      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 Additional_Time, Additional_Distance, or AdditionalCost attribute. This barrier type is referred to as an added cost point barrier.
    Two maps demonstrate how added cost point barriers affect a route analysis.

    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.
  • Additional_Timenumber (non-negative)default:0

    The added travel time when the barrier is traversed. This attribute is applicable only for added-cost barriers. The attribute value must be greater than or equal to zero, and its units are the same as those specified in the measurement_units parameter.

  • Additional_Distancenumber (non-negative)default:0

    The added distance when the barrier is traversed. This attribute is applicable only for added-cost barriers. The attribute value must be greater than or equal to zero, and its units are the same as those specified in the measurement_units parameter.

  • AdditionalCostnumber (non-negative)default:0

    The added cost when the barrier is traversed. This attribute is applicable only for added-cost barriers. The attribute value must be greater than or equal to zero.

  • 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.

    Learn more about bearing and bearing tolerance

  • 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.

Show example

This example shows how to use an added cost point barrier to model a five-minute delay at a railroad crossing. The BarrierType attribute is used to specify that the point barrier is of type added cost and the Attr_TravelTime attribute is used to specify the delay in minutes.

line_barriers

Specify one or more lines that prohibit travel anywhere the lines intersect the streets. For example, a parade or protest that blocks traffic across several street segments can be modeled with a line barrier. A line barrier can also quickly fence off several roads from being traversed, thereby channeling possible routes away from undesirable parts of the street network.

Two maps demonstrate how a line barrier affects finding a route between two stops.

The first map displays the shortest path between two stops. The second map shows the shortest path when several streets are blocked by a polyline barrier.

When specifying line barriers, you can set the name of each barrier using the following attribute:

Attributes for line_barriers

  • Namestring (length: 500)nullable

    The name of the barrier.

Show example

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.

polygon_barriers

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

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

Show attributes for polygon_barriers

Attributes for polygon_barriers

  • Namestringnullable

    The name of the barrier.

  • 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.

      Two maps demonstrate how a restriction polygon barrier affects finding a route between two stops.

      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 ScaledTimeFactor or ScaledDistanceFactor attribute.

      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.

    Two maps demonstrate how a scaled cost polygon barrier affects finding a route between two stops.

    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.

  • ScaledTimeFactornumber (non-negative)default:1

    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.

  • ScaledDistanceFactornumber (non-negative)default:1

    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.

  • ScaledCostFactornumber (non-negative)default:1

    The scaled cost when the barrier is traversed. This attribute is applicable only for scaled-cost barriers. The attribute value must be greater than or equal to zero.

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

Show example

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.

use_hierarchy

Specify whether hierarchy will be used when generating service areas.

  • true—The service will use hierarchy. When generating hierarchical service areas, the service prefers higher-order streets, such as freeways, to lower-order streets, such as local roads. This means that if a facility is located on a local road (the lowest level in a hierarchy), the service spans out on the local roads in that area, but it tries to step up the hierarchy to secondary and primary roads. Once on secondary and primary roads, the service ignores local roads throughout the rest of the service area. Mainly because of this hierarchical approach, hierarchical service areas are generated much faster compared to nonhierarchical service areas, as the service has to generate service areas from a relatively smaller subset of streets. Hierarchical service areas can be used to simulate the driver preference of traveling on freeways instead of local roads even if that means a longer trip. However, the areas can overlap some lower-order roads that can't be reached within the given travel distance or travel time. Consequently, hierarchical service areas can be less accurate.
  • false—The service will not use hierarchy. This results in service areas that are measured along all the streets, regardless of hierarchy level, and tend to be higher quality compared to their hierarchical counterparts.

Some service parameters are not applicable when generating hierarchical service areas.

  • The polygon_trim_distance parameter is ignored and, if specified, results in a warning message in the service response.
  • Generating detailed service areas, specified using a value of true for the detailed_polygons parameter, is not supported and results in a failed request.
  • The polygon_trim_distance parameter is ignored and, if specified, results in a warning message in the service response.
  • Generating detailed service areas, specified using a value of true for the detailed_polygons parameter, is not supported and results in a failed request.

restrictions

Specify whether the restrictions will be honored by the service.

A restriction represents a driving preference or requirement. In most cases, restrictions cause roads or pathways to be prohibited, but they can also cause them to be avoided or preferred. For instance, using the Avoid Toll Roads restriction will result in a route that will include toll roads only when it is required to travel on toll roads to visit a stop. Use Height Restriction to route around clearances that are lower than the height of the vehicle. If the vehicle is carrying corrosive materials, you can use the Any Hazmat Prohibited restriction to prevent hauling the materials along roads where it is marked as illegal to do so.

The parameter value is specified as a comma-separated list of restriction names. A value of null indicates that no restrictions will be used when finding the best route, but only when travel_mode is set to Custom.

time_impedance

Allowed values: Minutes, TravelTime, WalkTime, TruckMinutes, TruckTravelTime

Specify time-based impedance.

distance_impedance

Allowed values: Miles, Kilometers

Specify distance-based impedance.

The value represents the travel distance along road segments or on other parts of the transportation network.

  • Miles—Length measurements along roads are stored in miles and can be used for performing analysis based on shortest distance.
  • Kilometers —Length measurements along roads are stored in kilometers and can be used for performing analysis based on shortest distance.

impedance

Allowed values: TravelTime, Minutes, TruckTravelTime, TruckMinutes, WalkTime, Miles, Kilometers

Specify the impedance.

Impedance is a value that quantifies travel along the transportation network. Travel distance is an example of impedance; it quantifies the length of walkways and road segments. Similarly, drive time—the typical time it takes to drive a car along a road segment—is an example of impedance. Drive times may vary by type of vehicle—for instance, the time it takes for a truck to travel along a path tends to be longer than a car—so there can be many impedance values representing travel times for different vehicle types. Impedance values may also vary with time; live and typical traffic reference dynamic impedance values. Each walkway and road segment stores at least one impedance value. When performing a network analysis, the impedance values are used to calculate the best results, such as finding the shortest route—the route that minimizes impedance—between two points.

The parameter can be specified using the following values:

  • TravelTime—Historical and live traffic data is used. This option is good for modeling the time it takes automobiles to travel along roads at a specific time of day using live traffic speed data where available. When using TravelTime, you can optionally set the TravelTime::Vehicle Maximum Speed (km/h) attribute parameter to specify the physical limitation of the speed the vehicle is capable of traveling.
  • Minutes—Live traffic data is not used, but historical average speeds for automobiles data is used.
  • TruckTravelTime—Historical and live traffic data is used, but the speed is capped at the posted truck speed limit. This is good for modeling the time it takes for the trucks to travel along roads at a specific time. When using TruckTravelTime, you can optionally set the TruckTravelTime::Vehicle Maximum Speed (km/h) attribute parameter to specify the physical limitation of the speed the truck is capable of traveling.
  • TruckMinutes—Live traffic data is not used, but the smaller of the historical average speeds for automobiles and the posted speed limits for trucks are used.
  • WalkTime—The default is a speed of 5 km/hr on all roads and paths, but this can be configured through the WalkTime::Walking Speed (km/h) attribute parameter.
  • Miles—Length measurements along roads are stored in miles and can be used for performing analysis based on shortest distance.
  • Kilometers—Length measurements along roads are stored in kilometers and can be used for performing analysis based on shortest distance.

If you choose a time-based impedance, such as TravelTime, TruckTravelTime, Minutes, TruckMinutes, or WalkTime, the measurement_units parameter must be set to a time-based value; if you choose a distance-based impedance such as Miles, Kilometers, the measurement_units must be distance-based.

polygon_detail

Specify the level of detail for the output service area polygons. The parameter can be specified using the following values:

  • Standard—Polygons will be created with a standard level of detail. Standard polygons are generated quickly and are fairly accurate, but quality deteriorates somewhat as you move toward the borders of the service area polygons. This is the default.
  • Generalized—Generalized polygons will be created using the hierarchy present in the network data source to produce results quickly. Generalized polygons are inferior in quality compared to standard or high-precision polygons.
  • High—Polygons will be created with the highest level of detail. Holes in the polygon may exist; they represent islands of network elements, such as streets, that couldn't be reached without exceeding the cutoff impedance or due to travel restrictions This option should be used for applications in which precise results are important.

If your analysis covers an urban area with a grid-like street network, the difference between generalized and standard polygons will be minimal. However, for mountain and rural roads, the standard and detailed polygons may present significantly more accurate results than generalized polygons.

output_type

Allowed values: Polygons, Lines, Polygons and Lines

Specify the type of output to be generated. Service area output can be line features representing the roads reachable before the cutoffs are exceeded or the polygon features encompassing these lines (representing the reachable area).

  • Polygons—The service area output will contain polygons only.
  • Lines—The service area output will contain lines only.
  • Polygons and lines—The service area output will contain both polygons and lines.

save_output_network_analysis_layer

Specify whether the service will save the analysis settings as a network analysis layer file.

You cannot work directly with this file even when you open the file in an ArcGIS Desktop application such as ArcGIS Pro. It is meant to be sent to Esri Technical Support to diagnose the quality of results returned from the service.

  • true—The network analysis layer file will be saved. The file can be downloaded from the URL provided as part of the output_network_analysis_layer_package parameter.

  • false—The network analysis layer file will not be saved.

output_format

type:enumdefault:Feature Set

Allowed values: Feature Set, JSON File, GeoJSON File

Specify the format in which the output features will be returned.

  • Feature Set—The output features will be returned as feature classes and tables.

  • JSON File—The output features will be returned as a compressed file containing the JSON representation of the outputs. When this option is specified, the output is a single file (with a .zip extension) that contains one or more JSON files (with a .json extension) for each of the outputs created by the service.

  • GeoJSON File—The output features will be returned as a compressed file containing the GeoJSON representation of the outputs. When this option is specified, the output is a single file (with a .zip extension) that contains one or more GeoJSON files (with a .geojson extension) for each of the outputs created by the service.

context

This parameter contains additional settings that affect task operation, for example, the spatial reference of the output features.

overrides

ignore_invalid_locations

Specify whether invalid input locations will be ignored.

  • true—Network locations that are unlocated will be ignored and the analysis will run using valid network locations only. The analysis will also continue if locations are on non-traversable elements or have other errors. This is useful if you know the network locations are not all correct, but you want to run the analysis with the network locations that are valid.
  • false—Invalid locations will not be ignored. Do not run the analysis if there are invalid locations. Correct the invalid locations and rerun the analysis.

Response details

On successful completion, the service returns the best route and travel directions between the incident and the chosen facility and the status indicating whether the analysis was successful using the following response objects:

service_areas

Use this parameter to get the area that can be reached from the input location within a given travel time or travel distance. The polygon_overlap_type, polygons_for_multiple_facilities, polygon_trim_distance, and the polygon_simplification_tolerance parameters highly influence the shape of the output service areas. The service area geometries are returned in the spatial reference specified as the context parameter.

Show attributes for output service areas
  • Namestring (length: 1024)nullable

    The name of the service area. It is based on the name of the associated facility and the cutoffs; for example, Store1: 0.0 – 5.0 represents a service area that covers all traversable streets within five minutes of a facility named Store1 .

    The break values are returned without the name of the facility, for example, 0.0 – 5.0 , when the polygons_for_multiple_facilities property is set to Merge by Break Value .

  • FromBreaknumbernullable

    The lower bound of the service area's impedance cutoff range. The unit for this field is based on the unit of the impedance attribute set for the analysis.

    The value is in the units specified in the break_units parameter.

  • ToBreaknumbernullable

    The upper bound of the service area's impedance cutoff range. The value is in the same units as the FromBreak field values.

  • FacilityOIDintegernullable

    The ObjectID value of the input facility feature used to generate the service area polygon. This field is often used to join information from the input facilities.

    Multiple facilities can be associated with one service area when the polygons_for_multiple_facilities property is set to Merge by Break Value; therefore, the FacilityOID field values are set to null when the service areas are merged.

  • FacilityIDintegernullable

    The unique identifier of the associated facility that is automatically generated by the analysis.

    Multiple facilities can be associated with one service area when the polygons_for_multiple_facilities property is set to Merge by Break Value; therefore, the FacilityID field values are set to null when the service areas are merged.

  • Name_1string (length: 500)nullable

    The name of the facility a service area is associated with.

  • Breaksstring (length: 128)nullable

    The values for this field are copied from the Breaks field on the input facilities.

  • AdditionalTimenumber (non-negative)nullable

    The values for this field are copied from the AdditionalTime field on the input facilities.

  • AdditionalDistancenumber (non-negative)nullable

    The values for this field are copied from the AdditionalDistance field on the input facilities.

  • AdditionalCostnumber (non-negative)nullable

    The values for this field are copied from the AdditionalCost field on the input facilities. This field is included only when the travel mode used for the analysis has an impedance attribute that is neither time-based nor distance-based.

output_facilities

Provides access to the attributes of the facilities that are used in the service area analysis. You can use the attributes from this data type, such as the Status field, to determine why a facility was not used in the analysis.

Show attributes for output facilities
  • Namestring (length: 500)nullable

    The name of the facility. The values for this field are copied from the Name field on the input facilities.

  • 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
  • CurbApproachintegernullable

    The direction a vehicle may arrive at and depart from the facility. The values for this field are copied from the CurbApproach field on the input facilities.

  • Statusint enum

    Allowed values: 0, 1, 2, 3, 4, 5, 6, 7

    Indicates the status of the point with respect to its location on the network and the outcome of the analysis. The possible values are as following:

    • 0: OK.The point was located on the network.
    • 1: Not Located. The point was not located on the network and was not included in the analysis.
    • 2: Network element not located. The network element identified by the point's network location fields cannot be found. This can occur when a network element where the point should be was deleted, and the network location was not recalculated.
    • 3: Element not traversable. The network element that the point is located on is not traversable. This can occur when the element is restricted by a restriction attribute.
    • 4: Invalid Field Values. Field values fall outside a range or coded-value domain. For example, a negative number exists where positive numbers are required.
    • 5: Not reached. The point cannot be reached by the solver. The point may be on a separate, disconnected area of the network from the other inputs, or barriers or restrictions prevent travel to or from the point.
    • 6: Time window violation. The point could not be reached within the designated time windows. This status only applies to network analysis types that support time windows.
    • 7: Not located on closest. The closest network location to the point is not traversable because of a restriction or barrier, so the point has been located on the closest traversable network feature instead. If time windows are used and the route arrives early or late, the value changes to 6 (Time window violation)
  • SnapXnumber (non-negative)

    The x-coordinate of the position on the network dataset where the point was located, in the coordinate system of the network dataset.

  • SnapYnumber (non-negative)

    The y-coordinate of the position on the network dataset where the point was located, in the coordinate system of the network dataset.

  • SnapZnumber (non-negative)

    The z-coordinate of the position on the network dataset where the point was located, in the coordinate system of the network dataset. The SnapZ attribute is 0 if the network is two-dimensional.

  • DistanceToNetworkInMetersnumber (non-negative)

    The distance in meters between the point's geographic location and the position where it was located on the network.

  • FacilityOIDintegernullable

    The ObjectID value of the input facility.

  • Bearingnumber (non-negative)nullable

    The values for this field are copied from the Bearing field on the input facilities.

  • BearingTolnumber (non-negative)nullable

    The values for this field are copied from the BearingTol field on the input facilities.

  • NavLatencynumber (non-negative)nullable

    The values for this field are copied from the NavLatency field on the input facilities.

  • Breaksstring (length: 128)nullable

    The values for this field are copied from the Breaks field on the input facilities.

  • AdditionalTimenumber (non-negative)nullable

    The values for this field are copied from the AdditionalTime field on the input facilities.

Examples

Calculate 5-, 10-, 15-minute drive-time polygons around store locations

This example shows how to calculate the 5-, 10-, and 15-minute drive-time polygons around a store. The store location is specified as the facilities parameter. The drive-time polygons need to be drawn on an ArcGIS Online basemap that uses the Web Mercator spatial reference. Therefore, the env:outSR parameter is specified with a value of 102100 to return polygon geometries in the appropriate spatial reference. The default values for all the other parameters are appropriate for this request and are not specified.

The first request submits a job and returns the job id.
