Drivers will soon be able able to find out exactly where there is a traffic jam with the development of a new satellite navigation system, according to scientists.
The Congestion Avoidance Dynamic Routing Engine (Cadre) shares information from sat-navs in other vehicles to create a picture of how busy roads are.
The high-tech device then interprets the live traffic data to warn drivers of queues ahead and how to avoid them.
The project is being developed by a consortium, consisting of the University of Portsmouth, ComSine, Smartcom Software, the Transport Research Laboratory, ViaMichelin and Hampshire County Council.
The device relies on artificial intelligence software being developed by the University of Portsmouth's Institute of Industrial Research (IIR).
Dr David Brown, head of the IIR, said: "The system interprets live data from current traffic conditions so the motorist receives up-to-the-minute advice and can make an informed choice.
"It's designed to take the pain out of that agonising decision about whether to try an alternative route which could be equally congested."
The system, which could be in the shops in 18 months, takes into account how traffic speeds vary by day of the week and time of day and even on individual roads.
