Creating a travel time isochrone map is easy

When using the TravelTime platform API it’s possible to create travel time isochrones using multiple modes of transport – a more relevant alternative to geodistance searching. In one API call you can generate a travel time shape, filter points of interest by travel time and generate A to B routes. The map generator tool can be used:

  • Within any existing GIS platform
  • On any website or app
  • On top of any map you like – whether it’s a Google Map or another provider

Replace geodistance queries

The shape drawn below shows all locations reachable within a specified travel time from a point of origin. In this example it displays all reachable locations from Central London within 45 minutes using public transport at 6pm on a Wednesday evening.

In order to generate this shape the API needs:

  1. An arrival / departure time (Depart at 6pm, Wednesday evening)
  2. A mode of transport (public transport)
  3. A point of origin (Waterloo)
  4. The maximum travel time (45 mins)

Arrival / Departure time

The example above draws an isochrone map assuming the user needs to depart at 6pm rather than arrive at this time – similar to how the standard ‘near me’ search works. Switching to arrival time would change this shape as the example below shows.

Use case for generating maps with an arrival time: someone searching for a new job can see which locations are reachable within a 1 hour commute if they were to arrive at 9am. It assumes the user can depart from the point of origin up to 1 hour before their specified arrival time.

Use case for drawing maps with a departure time: a supermarket can set up a geofence area within 10 minutes drive of a store. This will push a message to any customers with the app, alerting them to any local offers.

Mode of transport

When using the API you can choose from:

  • Walking
  • Cycling
  • Driving
  • Public transport
    • Train
    • Tube
    • Bus
    • Coach
    • Ferry
  • As well as combining modes such as driving and train or cycling and ferry

Point of origin / interest

The API can create isochrones assuming there is more than one point of origin. When there is more than one point of origin, isochrone map layers can:


two isochrone map shapes by travel time


two isochrone map shapes union by travel time combined North London

Use cases:

  • A family looking for an ideal location to buy a new home that’s within reach of their current workplace or school location
  • A retailer plotting the best location of a new store based on their current store locations, their competitor’s stores and their customer base

Maximum travel time

This is specified within seconds using the API, however it can account for up to 12 hours total travel time.
