Travel Distance overlay for 500m travel distance to a school (blue arrow), over roads with pedestrian traffic (sidewalks)

The Travel Distance Overlay is a grid overlay which shows the distance that can be traveled from a certain starting point (routing area). The traffic is split between motorized and pedestrian traffic, based on the road type (roads vs sidewalks).

The overlay also uses an additional fill distance, which allows the result to expand to the area around the accessible roadways, to include accessible surrounding constructions. This allows users to query constructions that are within acceptable distance of cells which are within the travel distance.

The calculation model behind the overlay is based on the same algorithm as used in the Watershed Overlay.

The travel distance overlay can be used to visualise the travel distance from certain areas of interest (schools, shops, sports centers, etc), based on the roads project area. If we take a school as example, we can visualise which houses (and other buildings), within a range of 20m to a connecting sidewalk, are within a walking distance of 500m from the school of the example.
