| 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_cutoff | Default impedance value at which to cut off searching for destinations for a given origin. If the accumulated impedance becomes higher than the cutoff value, the traversal stops. The default can be overridden by specifying the cutoff value on the origins. (In, Optional) |
 | default_number_destinations_to_find | Default number of destinations to find for each origin. The default can be overridden by specifying a value for the TargetDestinationCount property on the origins. (In, Optional) |
 | hierarchy | The parameter is not used if a hierarchy attribute is not defined on the network dataset used to perform the analysis. In such cases, use "#" as the parameter value. (In, Optional) |
 | hierarchy_settings | Prior to version 10, this parameter allowed you to change the hierarchy ranges for your analysis from the default hierarchy ranges established in the network dataset. At version 10, this parameter is no longer supported and should be specified as an empty string. If you wish to change the hierarchy ranges for your analysis, update the default hierarchy ranges in the network dataset. (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 OD cost matrix analysis will be performed. (In, Required) |
 | out_network_analysis_layer | Name of the OD cost matrix network analysis layer to create. (In, Required) |
 | output_layer | Network Analyst Layer (out, Optional) |
 | output_path_shape | No matter which output shape type is chosen, the best route is always determined by the network impedance, never Euclidean distance. This means only the route shapes are different, not the underlying traversal of the network. (In, Optional) |
 | ParameterInfo | The parameters used by this tool. For internal use only. |
 | restriction_attribute_name | List of restriction attributes to apply during the analysis. (In, Optional) |
 | ToolboxDirectory | The directory of this tool's toolbox. |
 | ToolboxName | The name of this tool's toolbox. |
 | ToolName | The name of this tool. |
 | UTurn_policy | Restrict or permit U-turns at junctions that could occur during network traversal between stops. (In, Optional) |
