| Name | Description |
| accumulate_attribute_name | List of cost attributes to be accumulated during analysis. These accumulation attributes are purely for reference; the solver only uses the cost attribute specified by the Impedance attribute parameter to calculate the route. (In, Optional) |
| Alias | The alias for this tool's toolbox. |
| default_break_values | Default impedance values indicating the extent of the service area to be calculated. The default can be overridden by specifying the breaks value on the facilities. (In, Optional) |
| excluded_source_name | Specifies the list of network sources to be excluded when generating the polygons. The geometry of traversed elements from the excluded sources will be omitted from all polygons. (In, Optional) |
| impedance_attribute | The cost attribute to be used as impedance in the analysis. (In, Required) |
| in_network_dataset | The network dataset on which the service area analysis will be performed. (In, Required) |
| line_type | Specifies the type of lines to be generated based on the service area analysis. Selecting the TRUE_LINES or TRUE_LINES_WITH_MEASURES option for large service areas will increase the amount of memory consumed by the analysis. (In, Optional) |
| lines_source_fields | Include network source fields in lines (in, Optional) |
| merge | Specifies the options to merge polygons that share similar break values. This option is applicable only when generating polygons for multiple facilities. (In, Optional) |
| nesting_type | Specifies the option to create concentric service area polygons as disks or rings. This option is applicable only when multiple break values are specified for the facilities. (In, Optional) |
| out_network_analysis_layer | Name of the service area network analysis layer to create. (In, Required) |
| output_layer | Network Analyst Layer (out, Optional) |
| overlap | Determines if overlapping lines are generated when the service area lines are computed.
(In, Optional) |
| ParameterInfo | The parameters used by this tool. For internal use only. |
| poly_trim_value | Specifies the distance within which the service area polygons are trimmed. The parameter includes a value and units for the distance. The default value is 100 meters. (In, Optional) |
| polygon_trim | Trim Polygons (in, Optional) |
| polygon_type | Specifies the type of polygons to be generated. (In, Optional) |
| restriction_attribute_name | List of restriction attributes to apply during the analysis. (In, Optional) |
| split | Split lines when they cross a service area break (in, Optional) |
| ToolboxDirectory | The directory of this tool's toolbox. |
| ToolboxName | The name of this tool's toolbox. |
| ToolName | The name of this tool. |
| travel_from_to | Specifies the direction of travel to or from the facilities. (In, Optional) |
| UTurn_policy | Restrict or permit U-turns at junctions that could occur during network traversal between stops. (In, Optional) |
