This tool filters out which locations fall inside and outside of a travel time catchment area and groups them. It then calculates travel times from an origin to many destinations. It is possible to use this to create a travel time or distance matrix.
Only the key parameter fields are configurable. The more complex parameter fields (available in the Advanced tool) take standard, sensible values.
| Parameter | Description | Data Type |
|---|---|---|
| Departure Locations | The point layer to be used as the departure locations | Picklist |
| Travel Mode | Method of transport | Picklist |
| Time Zone | Time zone | Picklist |
| Departing / Arriving | Whether the chosen time will be for departing or arriving (see below) | Picklist |
| Departing / Arriving Time | The departure or arrival time. This will get updated as per the time zone selected. | Calendar Format - dd/mm/yyyy hh:mm |
| Travel time | The maximum journey time (in minutes) | Text |
| Arrival Locations | The point layer to be used as the arrival locations | Picklist |
| Output Layer | Where to save the output layer – NB must be saved into the project Geodatabase | Folder connection |
An Arriving search filters the Departure Locations – “*where can I set off from to reach my destination by a certain time?*”
A Departing search filters the Arrival Locations – “*where can I get to by leaving my origin at a certain time?*”
If using a multi-point layer in the Locations field (i.e multiple origins from which to run the filter), the tool will mark a point from the Points to Filter layer as reachable if it is reachable from any of the origins; it does not need to be reachable from all of the origins.
