The stress of commuting through rush-hour traffic could soon be reduced through a trial in the North East that seeks to streamline city-centre congestion.
New sat-nav technology being tested could help drivers adjust their speed so they can pass through a series of lights on green.
The project, headed by Newcastle University and Newcastle City Council, is being developed to reduce traffic jams and pollution associated with stop-start driving.
Two other benefits of the system will be a forward collision warning and a red light violation warning, which tells drivers when someone has jumped a red light.
The pilot is part of a £8.6 million project called Compass4D involving seven European cities.
