How far can I travel?

Isochrone maps show travel times from a given location. Travel Time is a great example of an isochrone map created with the Google Maps API.

Travel Time allows users in four US cities to find out the travel times from any location in each of the cities. Click anywhere in Denver, San Francisco, Seattle or Boulder and you can view an isochrone map of the time it will take to travel anywhere in the city on the public transit system.

The map includes the option to include two points of origin, so that you can compare the travel times from both locations. It even includes an option to view the travel times for different days of the week and for different times of the day.


Mapnificent is a Google Maps based application that shows you how far you can travel on public transport for any given length of time, in a number of major cities around the world.

Mapnificent allows users to drop a marker anywhere in a city and adjust a slide control to define a commuting time. The map then displays the commutable area using an isochrone layer on the map. Users can adjust the slide control to show longer or shorter commute time zones.
