Learning and Development News - Information superhighway

Road users can now benefit from real-time information about journey times via new electronic roadside signs along the M25.  The new service, which will give expected travel times to specific M25 junctions was trialled in the West Midlands and South West, proving to be  very popular with motorists.

The information, which also warns to delays in the event of incidents on the motorway, is part of a new service from the National Traffic Control Centre aimed at helping motorists make more informed decisions about their journeys. The M25, is the latest area to be covered by the service, which now includes the original trial area in the West Midlands, the M6 up to Carlisle and the M5 down to the South West.

Roads Minister Tom Harris said:

"We are making best use of our technology to help drivers find out about traffic conditions on their route both before they leave and during their journey.

"Displaying journey times on our electronic signs gives drivers greater certainty about the time it will take to get them to their destinations. It also helps them to consider options such as changing their route or taking a break if there are traffic delays on the road ahead."

The system uses current information captured from automatic number plate recognition cameras which it compares against historical traffic data on that particular stretch of motorway. The travel time is automatically recalculated every five minutes. If an incident, such as a collision, causes delays on the motorway above a pre-determined threshold, the sign will automatically switch from showing the travel time message to displaying the estimated delay time. If the sign is needed to display an important safety message, the travel or delay time will be over-written.

This is one of three new information services being launched by the Highways Agency. Traffic Radio lets drivers hear the latest traffic news on England's motorways and major 'A' roads. It is now available on DAB digital radio and on the internet at http://www.trafficradio.org.uk. CCTV pictures will be available to the media and the general public by spring 2008, so that people can check the conditions on the road before they leave home or work.
