Motorways: Road Traffic

Volume 504: debated on Monday 18 January 2010

To ask the Minister of State, Department for Transport with reference to the answer to the right hon. Member for East Yorkshire of 23 June 2009, Official Report, column 768W, on motorways, what assessment he has made of the effects on the level of motorway congestion of the DAB radio service Traffic Radio since its introduction. (309477)

Traffic Radio is one of a suite of Highways Agency information services designed to provide road users with access to the very latest traffic information.

Research has shown that awareness and usage of information services can influence levels of motorway congestion. It is not possible to directly correlate the impact of Traffic Radio to motorway congestion due to the complexity of assessing one information service in isolation from the others. In addition, information is only one of a series of measures that can contribute towards congestion reduction.

The Highways Agency is undertaking a piece of research to evaluate whether the anticipated benefits of Traffic Radio, as outlined in its original specification, have been realised. This work is due to be completed by April 2010 and will be supplemented by information from the agency's annual Measuring Improvements in Network Information Services survey.
