Reverse Direction Isoline

This example calculates an isoline in the reverse direction. The result is the answer to this question: From where can I get to the destination within a given range. This can be useful to determine which vehicles from a fleet of vehicles (Taxi service) can get to the destination within a given time, for example. To trigger calculation in reverse direction, use the destination parameter instead of start.
