Distance-derived polygons

You may have a use-case where you need the polygons to represent a set distance along the network, as opposed to time. With the edge weight option, you can change the polygon distances you define to be meters, not seconds.

Set edge weight type using travelOptions.setEdgeWeight('distance');.

In this example, we have defined polygons representing travel distances of 1000m, 2000m, and 3000m.

Note: due to the nature of transit 'stops' distance polygons will only work with travel types 'walk', 'bike', and 'car'.
