The fastest way through jams.

We all know there are situations on the roads that we can’t predict – like traffic jams due to accidents or road works.

For times like this, TomTom has developed a unique technology called HD Traffic, which is the most accurate real-time traffic information you can get. Standard traffic services collect information mainly from traffic cameras and road sensors. But these are typically installed only on the busiest roads – meaning they miss the bigger picture. Updates to these services can also be delayed by up to 15 minutes.

TomTom’s HD Traffic, on the other hand, uses extra data: anonymous mobile phone signals. That gives us more accurate traffic information and fresh updates every three minutes. Unlike with other satnavs, it also covers both main and secondary roads.

With this exclusive live traffic information, you can easily decide which route will get you there fastest, and know when you'll arrive.

HD Traffic follows you throughout Belgium, France, Germany, the Netherlands, Portugal, Switzerland and the UK, and is constantly expanding to more countries.

HD Traffic uses a revolutionary new source of traffic information: the flow of millions of anonymous mobile phone users on the road. TomTom receives live data from major mobile phone operators and analyses it in real time, to get a complete and accurate picture of the traffic situation.

From this anonymous data, TomTom knows exactly where, in which direction and at what speed all these mobile phone users are travelling throughout the road network. This real-time data is combined with other existing quality traffic information sources used by other broadcasting services, like RDS-TMC (Radio Data System – Traffic Message Channel).

As a result, HD Traffic is the most complete and reliable traffic information service available today.

HD Traffic covers more than 97% of UK motorways, slip roads, trunk roads and A roads. This is more than 10,000 km of roads than other traffic information providers, such as RDS-TMC.

HD Traffic gives you traffic updates up to five times more frequently than other providers. That means that instead of waiting up to 15 minutes to hear about a jam, you can be sure you'll know about it within just three minutes.
