People using Google Maps can now view live traffic information.

Google Traffic Maps is a joint venture between the search engine and the Highways Agency, an executive agency of the Department for Transport.

The system overlays a colour-coded layer of the average speeds on England's motorways and major 'A' road network onto Google Maps. There are different colours indicating the current speed of traffic.

The Highways Agency provides its traffic information to Google in a Datex II format, which is a European standard developed specifically for road data information exchange.

It provides real-time traffic information and predictions based on past conditions, helping motorists to plan their journeys ahead to avoid congestion.

Denise Plumpton, director of information at the Highways Agency, said: "I'm delighted that we are the first country in Europe to work with Google and use our information for the benefit of road users across the country.

"This sort of project is a key part of our information strategy aimed at getting traffic information out to motorists where and when they need it.”
