While classic traffic light cameras - sometimes even with chemical film - are still very common in Europe, their days are numbered. That doesn't mean that red light violations won't be controlled any longer, but the cameras are becoming multifuctional and even more inconspicuous. A rather elegant traffic control system is being installed in Estonia.
The PoliScan systems will be deployed at two sites in Tallinn to enforce red light as well as speed limit violations. Besides these classical PoliScan applications, access to the bus lane will also be controlled. As soon as a vehicle runs the red light, high-resolution digital cameras capture the vehicle including driver and licence plate. The first picture is taken when the vehicle crosses the stop line, the second one is taken in the intersection. In Tallinn an additional camera is installed behind the arriving vehicles, across from the traffic lights, to document the traffic light phase at the moment of the violation. Speeding and unauthorized driving in the bus lane are enforced as well – no matter if the lights are red or green.
PoliScan systems operate based on LIDAR (Light Detection And Ranging) and without any in-road loops or sensors. The laser technology allows traffic safety enforcement even if the vehicles change lanes or tailgate.
