Abstract
A traffic safety system is provided for controlling the entry of motorists onto one way roads. The system has a motion detection unit which identifies the presence of motor vehicles travelling the wrong direction on one way roads, highway exit ramps and entrance ramps. Upon detection of a vehicle, the system activates audible and visual warnings. If the motorist does not stop moving, a barrier will deploy and a camera unit will photograph the license plate of the vehicle before transmitting same to local authorities. Additionally, a set of warming indicators positioned at a far end of the road are provided, which illuminate when the system is deployed, notifying travelers of a road blockage.
