Purpose

What is the Traffic API?

The Traffic API is a suite of web services designed for developers to create web and mobile applications around real-time traffic. These web services can be used via RESTful APIs.

The offering is split into:

  • Traffic Incidents: This provides an accurate view about traffic jams and incidents around a road network.
  • Traffic Flow: This provides real time observed speeds and travel times for all key roads in a network.

The Traffic API web services are based on the real-time traffic data TomTom Traffic™.

Getting started

  1. Register/Sign in to the TomTom Developer Portal.
  2. Request an evaluation API key to access this service.
  3. Read the API documentation and start coding.
  4. Consider using the TomTom Maps SDK for Android, for iOS, and for Web.

Common use cases you can implement

Display:
Real-time traffic incident data on a map, or display real-time traffic segment speed data on a map.
Traffic delay data with delay details like location, length, and delay.
Segment details like free-flow speed, current speed, and confidence values.
Obtain current traffic speed information with information about the real-time speed per road segment and display them on a TomTom map.
Indicate:
The severity of the current traffic condition with colored tubes indicating the delay severity.
The accurate location of slowdowns with colored tubes indicating the delay severity.
Combine:
The Traffic Flow Speed information with other real-time traffic information for a Traffic Management Monitoring application.

Features

Harness the power of TomTom Traffic™ for your application!

In both the Traffic Flow and Traffic Incident RESTful APIs, different road categories are displayed depending on the zoom level.

TomTom's Traffic Incident RESTful API

  • Is updated every minute with the very latest traffic incident and delay information.
  • Returns detailed information about traffic jams and traffic related incidents. Details include: start-location, end-location, road-name, type of delay, length (in time) of the delay, significance, and distance.
  • The Raster and Vector Incident Tile APIs provide traffic incident and delay information for display on your map view.

TomTom's Traffic Flow RESTful API

  • Is updated every minute with very latest traffic speed information.
  • Returns detailed information about traffic speed. Details include: current speed, freeflow speed, and quality indicator.
  • The Raster and Vector Flow Tile APIs provide traffic speed information for display on your map view. An option is provided to use the absolute or relative speed information.
