Advances in car navigation

News

Researchers are developing a new in-car navigation system which informs motorists about traffic jams and advises on the best route for their journey before they reach the congestion.

The Congestion Avoidance Dynamic Routing Engine (CADRE) uses Artificial Intelligence (AI) to interpret live traffic information shared between vehicles fitted with a special GPS.

The research is being conducted by a consortium, which includes Portsmouth University, ComSine, Smartcom Software, the Transport Research Laboratory, ViaMichelin and Hampshire County Council.

CADRE can sense traffic slowing down and building up into jams and works by monitoring other vehicles on the road, informing motorists 5 to 10 miles away of a situation and recommending steps to avoid it. The AI software is built around ‘fuzzy logic’ that mimics human reasoning.

Portsmouth University’s Institute of Industrial Research’s Dr David Brown said: ‘It’s designed to take the pain out of that agonising decision about whether to try an alternative route which could be equally congested.
