New smart system to reduce queues at roundabouts

Long queues at certain approaches to some roundabouts could be reduced using magnetic detection devices under the road surface, which would activate a traffic metering signal at another, less congested approach. Researchers have released a guide for technicians to implement this intelligent traffic system, already used on roundabouts in Australia and on various highway on-ramps.
