On two roads in Swindon, where speeding is commonplace, a pilot scheme is to be tested whereby speeding motorists will be shamed into slowing down.

Sensors in the road will detect speeding vehicles and change the next set of traffic lights to red, thereby holding up the surrounding cars also. There will be no warning as to where the sensors are located.

It is hoped that the scheme will encourage drivers to concentrate on what is happening on the road ahead.
