Parameters:

Parameter: Stops

Data Type: GPFeatureRecordSetLayer
Display Name Stops
Description: This tool routes between the stops specified in this parameter. A minimum of two stops are necessary to solve an analysis.When specifying the stops, you can set properties for each one, such as its name or service time, by using attributes. The stops can be specified with the following attributes:OBJECTID—The system-managed ID field.SHAPE—The geometry field indicating the geographic location of the incident.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.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. With this tool you can group up to 150 stops into one route.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 route name 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.)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. Generally, the location of a stop, such as a home, 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 stop location and its location on the street, if it is important to include that distance in the total travel distance.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 street; 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.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.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.

Parameter: Time_of_Day

Data Type: GPDate
Display Name Time of Day
Description: Specifies the time and date at which the routes should begin. If your network dataset contains live or historical traffic data, specifying a time-of-day results in a more accurate estimation of travel time between stops because the travel times account for the traffic conditions that are applicable for that date and time.The Time Zone for Time of Day parameter specifies whether this time and date refer to UTC or the time zone in which the stop is located.The tool ignores this parameter when Measurement Units isn't set to a time-based unit.

Default Value:
Parameter Type: esriGPParameterTypeOptional
Category: Advanced Analysis


Parameter: Time_Zone_for_Time_of_Day

Data Type: GPString
Display Name Time Zone for Time of Day
Description: Specifies the time zone of the Time of Day parameter.GEO_LOCAL—The Time of Day parameter refers to the time zone in which the first stop of a route is located. If you are generating many routes that start in multiple times zones, the start times are staggered in Coordinated Universal Time (UTC). For example, a Time of Day value of 10:00 a.m., 2 January, would mean a start time of 10:00 a.m. Eastern Standard Time (3:00 p.m. UTC) for routes beginning in the Eastern Time Zone and 10:00 a.m. Central Standard Time (4:00 p.m. UTC) for routes beginning in the Central Time Zone. The start times are offset by one hour in UTC.The arrive and depart times and dates recorded in the output Stops feature class will refer to the local time zone of the first stop for each route.UTC—The Time of Day parameter refers to Coordinated Universal Time (UTC). Choose this option if you want to generate a route for a specific time, such as now, but aren't certain in which time zone the first stop will be located.If you are generating many routes spanning multiple times zones, the start times in UTC are simultaneous. For example, a Time of Day value of 10:00 a.m., 2 January, would mean a start time of 5:00 a.m. Eastern Standard Time(UTC-5:00) for routes beginning in the Eastern Time Zone and 4:00 a.m. Central Standard Time (UTC-6:00) for routes beginning in the Central Time Zone. Both routes would start at 10:00 a.m. UTC.The arrive and depart times and dates recorded in the output Stops feature class will refer to UTC.

Default Value: GEO_LOCAL
Parameter Type: esriGPParameterTypeOptional
Category: Advanced Analysis
Choice List: [ UTC, GEO_LOCAL ]

Parameter: UTurn_Policy

Data Type: GPString
Display Name UTurn Policy
Description: The U-Turn policy at junctions. Allowing U-turns implies the solver can turn around at a junction and double back on the same street. Given that junctions represent street intersections and dead ends, different vehicles may be able to turn around at some junctions but not at others—it depends on whether the junction represents an intersection or dead end. To accommodate, the U-turn policy parameter is implicitly specified by how many edges, or streets, connect to the junction, which is known as junction valency. The acceptable values for this parameter are listed below; each is followed by a description of its meaning in terms of junction valency. ALLOW_UTURNS—U-turns are permitted at junctions with any number of connected edges, or streets. This is the default value. NO_UTURNS —U-turns are prohibited at all junctions, regardless of junction valency.ALLOW_DEAD_ENDS_ONLY—U-turns are prohibited at all junctions, except those that have only one adjacent edge (a dead end).ALLOW_DEAD_ENDS_AND_INTERSECTIONS_ONLY—U-turns are prohibited at junctions where exactly two adjacent edges meet but are permitted at intersections (junctions with three or more adjacent edges) and dead ends (junctions with exactly one adjacent edge). Oftentimes, networks modeling streets have extraneous junctions in the middle of road segments. This option prevents vehicles from making U-turns at these locations.The value of this parameter is overridden when Travel Mode (Travel_Mode in Python) is set to any value other than custom.

Parameter: Point_Barriers

Data Type: GPFeatureRecordSetLayer
Display Name Point Barriers
Description: Specifies point barriers, which are split into two types: restriction and added cost point barriers. They temporarily restrict traversal across or add impedance to points on the network. The point barriers are defined by a feature set, and the attribute values you specify for the point features determine whether they are restriction or added cost barriers. The fields in the attribute table are listed and described below. ObjectID: The system-managed ID field. Shape: The geometry field indicating the geographic location of the network analysis object.Name: The name of the barrier.BarrierType: Specifies whether the barrier restricts travel completely or adds cost when traveling through it. There are two options: Restriction (0)—Prohibits traversing through the barrier. This is the default value. Added Cost (2)—Traversing through the barrier increases the network cost by the amount specified in the Additional_Time and Additional_Distance fields. Use the value 0 for Restriction and 2 for Added Cost.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.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.

Category: Barriers


Parameter: Polygon_Barriers

Data Type: GPFeatureRecordSetLayer
Display Name Polygon Barriers
Description: Specifies polygon barriers, which are split into two types: restriction and scaled cost polygon barriers. They temporarily restrict traversal or scale impedance on the parts of the network they cover. The polygon barriers are defined by a feature set, and the attribute values you specify for the polygon features determine whether they are restriction or scaled cost barriers. The fields in the attribute table are listed and described below. ObjectID: The system-managed ID field. Shape: The geometry field indicating the geographic location of the network analysis object. Name: The name of the barrier. BarrierType: Specifies whether the barrier restricts travel completely or scales the cost of traveling through it. There are two options:Restriction (0)—Prohibits traversing through any part of the barrier. This is the default value.Scaled Cost (1)—Scales the impedance of underlying edges by multiplying them by the value of the ScaledCostFactor property. If edges are partially covered by the barrier, the impedance is apportioned and multiplied.Use the value 0 for Restriction and 1 for Scaled Cost.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.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.

Parameter Type: esriGPParameterTypeOptional
Category: Custom Travel Mode


Parameter: Use_Hierarchy_in_Analysis

Data Type: GPBoolean
Display Name Use Hierarchy in Analysis
Description: Specify whether hierarchy should be used when finding the shortest routes between points.Checked — Use hierarchy when finding routes. When hierarchy is used, the tool prefers higher-order streets (such as freeways) to lower-order streets (such as local roads) and can be used to simulate the driver preference of traveling on freeways instead of local roads even if that means a longer trip. This is especially true when finding routes to faraway facilities, because drivers on long-distance trips tend to prefer traveling on freeways where stops, intersections, and turns can be avoided. Using hierarchy is computationally faster, especially for long-distance routes, because the tool has to select the best route from a relatively smaller subset of streets. This is the default value.Unchecked — Do not use hierarchy when finding routes. If hierarchy is not used, the tool considers all the streets and doesn't prefer higher-order streets when finding the route. This is often used when finding short-distance routes within a city.The parameter is disabled if a hierarchy attribute is not defined on the network dataset used to perform the analysis.You can use the Force Hierarchy Beyond Distance parameter to force the solver to use hierarchy even if Use Hierarchy in Analysis is set to false.This parameter is ignored unless Travel Mode is set to Custom. When modeling a custom walking mode, it is recommended to turn off hierarchy since the hierarchy is designed for motorized vehicles.

To ensure facilities are not located on limited-access highways, for example, write a SQL expression like the following to exclude those source features: "Streets" "FUNC_CLASS not in('1', '2')". Note that barriers ignore the feature locator WHERE clause when loading.

Parameter: Route_Shape

Data Type: GPString
Display Name Route Shape
Description: Specify the type of route features that are output by the tool. The parameter can be specified using one of the following values:TRUE_LINES_WITHOUT_MEASURES— Return the exact shape of the resulting route based on the underlying streets.TRUE_LINES_WITH_MEASURES— Return the exact shape of the resulting route based on the underlying streets. Additionally, construct measures so the shape may be used in linear referencing.STRAIGHT_LINES— Return a straight line between the stops.NO_LINES— Do not return any shapes for the routes. This value can be useful in cases where you are only interested in determining the total travel time or travel distance between the stops. When the Route Shape parameter is set to True Shape, the generalization of the route shape can be further controlled using the appropriate value for the Route Line Simplification Tolerance parameter. No matter which value you choose for the Route Shape parameter, the best route is always determined by minimizing the travel time or the travel distance, never using the straight-line distance between stops. This means that only the route shapes are different, not the underlying streets that are searched when finding the route.

Parameter: Route_Line_Simplification_Tolerance

Data Type: GPLinearUnit
Display Name Route Line Simplification Tolerance
Description: Specify by how much you want to simplify the route geometry.The tool ignores this parameter if the Route Shape parameter isn't set to True lines with measures or True lines without measures. Simplification maintains critical points on a route, such as turns at intersections, to define the essential shape of the route and removes other points. The simplification distance you specify is the maximum allowable offset that the simplified line can deviate from the original line. Simplifying a line reduces the number of vertices that are part of the route geometry. This improves the tool execution time.The value of this parameter is overridden when Travel Mode (Travel_Mode in Python) is set to any value other than custom.

Parameter: Force_Hierarchy_Beyond_Distance

Data Type: GPDouble
Display Name Force Hierarchy Beyond Distance
Description: Specifies the distance after which the solver will force hierarchy when finding routes, even if hierarchy is not enabled. The units of this parameter are the same as those shown in the Distance Attribute Units parameter.Finding routes between stops that are far away while using the network's hierarchy tends to incur much less processing than finding the same routes without using the hierarchy. This parameter helps you govern the amount of processing that occurs when solving.A null value indicates that the hierarchy will never be enforced and the value of the Use Hierarchy in Analysis parameter will always be honored. If the input network dataset does not support hierarchy, specifying a value for this parameter will result in an error. A null value should be used in this case. This parameter is disabled unless the network dataset includes a hierarchy attribute.

Parameter: Save_Output_Network_Analysis_Layer

Data Type: GPBoolean
Display Name Save Output Network Analysis Layer
Description: Choose whether the output includes a network analysis layer of the results. In either case, feature classes containing the results are returned. However, a server administrator may want to choose to output a network analysis layer as well so that the setup and results of the tool can be debugged using the Network Analyst controls in the ArcGIS Desktop environment. This can make the debugging process much easier. In ArcGIS Desktop, the default output location for the network analysis layer is in the scratch folder. You can determine the location of the scratch folder by evaluating the value of arcpy.env.scratchFolder geoprocessing environment in the Python window. The output network analysis layer is stored as an LYR file whose name begins with _ags_gpna and is followed by an alphanumeric GUID.

Parameter: Time_Zone_for_Time_Windows

Data Type: GPString
Display Name Time Zone for Time Windows
Description: Specifies the time zone for the time window values on stops. The time windows are specified as part of TimeWindowStart and TimeWindowEnd fields on stops. This parameter is applicable only when the Use Time Windows parameter is checked (or set to True). GEO_LOCAL— The time window values associated with the stops are in the time zone in which the stops are located. For example, if the stop is located in an area that follows Eastern Standard Time and has time window values of 8 a.m. and 10 a.m., the time window values will be treated as 8 a.m. and 10 a.m. in Eastern Standard Time.UTC— The time window values associated with the stops are in the Coordinated Universal Time (UTC). For example, if the stop is located in an area that follows Eastern Standard Time and has time window values of 8 a.m. and 10 a.m., the time window values will be treated as 12 p.m. and 2 p.m. Eastern Standard Time, assuming the Eastern Standard Time is obeying the Daylight Saving Time. Specifying the time window values in UTC is useful if you do not know the time zone in which the stops are located or when you have stops in multiple time zones and you want all the time windows to start simultaneously. The UTC option is applicable only when your network dataset defines a time zone attribute. If your network dataset does not define a time zone attribute, then all time window values are always treated as GEO_LOCAL.

Parameter: Overrides

Data Type: GPString
Display Name Overrides
Description: Specify additional settings that can influence the behavior of the solver when finding solutions for the network analysis problems. The value for this parameter needs to be specified in JavaScript Object Notation (JSON). For example, a valid value is of the following form {"overrideSetting1" : "value1", "overrideSetting2" : "value2"}. The override setting name is always enclosed in double quotation marks. The values can be a number, Boolean, or a string. The default value for this parameter is no value, which indicates not to override any solver settings. Overrides are advanced settings that should be used only after careful analysis of the results obtained before and after applying the settings. A list of supported override settings for each solver and their acceptable values can be obtained by contacting Esri Technical Support.
