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 a fill distance to fill up an area adjacent to the roadways, to connect constructions such as housing. 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.
