Isochrones indicate the total area that can be reached within a given time and by means of a given mode of transportation. They support accessibility analyses. Historically, isochrones have helped answer questions like:

  • “What kind of foot traffic can we expect for a store, at this location?” or
  • “If we put a bus stop there, how many riders will live within a 5-minute walk?” or
  • “How many homes can a firehouse serve within a 10-minute drive?”

This plugin helps you to generate your own isochrones, right in your browser. With a starting location and Mapbox access token, the plugin will calculate isochrones up to 60 minutes via driving, cycling or walking.

Good Example

One example is a 60-minute isochrone emanating from just north of London. If you compare how far a car can travel northward, away from the city, compared to the squeeze entering downtown directly to the south where you'd have to cross the Thames, you can see how visually effective this way of communicating travel times is.
