The mission of TomTom is helping our customers arrive at their destinations faster, more safely and more reliably, regardless of their locations. We developed TomTom Intermediate Traffic to deliver detailed, real-time traffic content to business customers who integrate it into their own applications. Target customers for TomTom Intermediate Traffic include automotive OEMs, web and application developers, and governments. We deliver bulk traffic flow information that provides a comprehensive view of the entire road network.

TomTom delivered our first live traffic product in 2007 and our experience has taught us how to continue delivering the best traffic products in the market. Our real-time traffic products are created by merging multiple data sources, including anonymized measurement data from over 650 million GPS-enabled devices. Using highly granular data, gathered on nearly every stretch of road, we can calculate travel times and speeds for virtually any day or time. We focus on our travel information so our customers can focus on their own business objectives.

What is TomTom's Intermediate Traffic API?

The TomTom Intermediate Traffic API enables business customers to download real-time TomTom traffic data for their server-based systems.

The data provided is:

  • suitable for processing on the receiving end for online applications
  • for delivery to client devices
  • for analysis and display

Since customers are provided with direct access to the traffic data, they have control of more variables, such as the frequency rate at which the data is pulled from the server.

Available feeds and formats

TomTom Intermediate Traffic Events provides information on the current observed congestion and incidents on roads in all countries where we offer this service. Traffic 'incidents' in this context includes information like closed roads, lane closures, construction zones, and accidents.

TomTom Intermediate Traffic Flow contains information on the current observed speed on roads in all countries where TomTom live traffic information services are available.

DATEX II is an industry standard for information exchange between service providers, application developers and traffic management centers. More information is at

Protobuf is a method for encoding structured data in an efficient yet extendable format. Protobuf is highly recommended for TomTom Traffic Flow since it is more efficient for the transmission of data than XML based formats. For the detailed version of TomTom Traffic Flow, protobuf is mandatory. See for more information.

Use cases

TomTom Intermediate Traffic has the following common use cases:

**Navigation and mobile applications: **current and predicted speed, and delay information enables better route calculations and more accurate ETAs. These help drivers save time, fuel, and money.

**Navigation and mobility applications: **real-time content enables the creation of a visual layer of live traffic congestion and events that can be displayed on a map or navigation application.

**Fleet, Logistics and On-Demand services: **routing drivers around traffic incidents enables more accurate ETAs and improves customer service.

**Traffic management: **real-time traffic insights enable road authorities, highway agencies, and traffic management centers to monitor traffic with an accurate, detailed view of average speeds and incidents across the entire road network.

A secure connection

TomTom Intermediate Traffic is a secure service that uses an API Key in combination with IP-address whitelisting. Customers accessing the service must connect from a (set of) fixed IP address(es) that were previously assigned to the profile, or access to the service is rejected. For those customers who use cloud-based servers, TomTom uses a different security certification process for granting access. This process is described in the Authentication page.
