VODAFONE and the AA have teamed up to develop the congestion-busting device Personal Roadwatch 1800 - a system that warns drivers of potential delays up to 15 miles or three junctions ahead on all of Britain's motorways, trunk roads and major A roads. Ray Combs, general manager of AA Fleet Services, said: 'Tthe increasing amount of traffic on our roads means that delays occur all too often, disrupting and wasting valuable time for the business driver. Personal Roadwatch 1800 takes away the frustration of being stuck in traffic by alerting company car drivers to problems well in advance during their journeys.'

A special traffic information line supports the in-car device, with drivers on the Vodafone network able to dial 1800 to receive further details of current traffic conditions in their local area. Alan Harper, managing director of Vodafone, said: 'Drivers will always be better prepared for their journey if they have clear and concise access to relevant traffic information.'
