The AA and TomTom have teamed up to launch a new mobile app that provides traffic information to drivers in the UK.

The AA Roadwatch Pro app, powered by TomTom’s HD Traffic data, will alert users about traffic congestion on their planned routes to help them make more informed decisions.

TomTom Automotive and Licensing Managing Director Charles Cautley said that the AA Roadwatch Pro traffic app offers users access to accurate traffic information, conveniently sent through text alerts.

"This traffic information helps drivers to make more informed decisions about their journey and ultimately helps them to reach their destination faster," Cautley.

"The AA Roadwatch Pro app will alert users about traffic congestion on their planned routes to help them make more informed decisions."

TomTom’s Congestion Index reveals that nine UK cities feature in the top 60 of Europe’s most congested cities.

The Eddington Transport Study for the Department of Transport in the UK estimated that lowering delays by just 5% can save road users £2.5bn each every year.

With the help of TomTom’s real time traffic services, the AA Roadwatch Pro traffic app provides subscribers with a text alert in cases of traffic delays.

The app will also offer users immediate access to live traffic and roadwork information via detailed street-level maps.

The AA Roadwatch Pro traffic app can be downloaded from iTunes for a free 7-day trial period followed by an annual subscription of £1.99.
