サマリー
Returns a dictionary of travel mode objects that are available with the network dataset. The dictionary keys are the names of the travel modes and the dictionary values are the travel mode objects. The travel mode objects can be used to update a solver properties object (RouteSolverProperties, ClosestFacilitySolverProperties, ServiceAreaSolverProperties, ODCostMatrixSolverProperties, VehicleRoutingProblemSolverProperties, or LocationAllocationSolverProperties) before solving a particular analysis.
説明
One or more travel modes can be defined on a network dataset. This function can be used to populate a value list with the available travel modes given a network dataset. For example, a geoprocessing script tool can have a parameter of type String called Travel Modes that can be populated with a list of travel mode names once a network dataset has been selected in the tool dialog box.
If a network dataset does not support travel modes, this function returns an empty dictionary.
構文
GetTravelModes (network_dataset_path)
| パラメーター | 説明 | データ タイプ |
network_dataset_path | A variable that references the catalog path of the network dataset. The catalog path of a network dataset can be obtained from the dataSource property of a network dataset layer or a network analysis layer object. It can also be obtained from the catalogPath property of a network dataset describe object. | String |
戻り値
| データ タイプ | 説明 |
| Dictionary | A dictionary whose keys are the travel mode names and values are the travel mode objects. |
コードのサンプル
Get the travel modes in a network dataset and print the Walking Time travel mode.
import arcpy
nds = 'C:/Data/SanDiego.gdb/Transportation/Streets_ND'
travel_modes = arcpy.na.GetTravelModes(nds)
print(travel_modes['Walking Time'])
