Red-light enforcement - Overview

Red-light jumping is one of the most critical traffic violations. The fact that a traffic light is red usually implies that the lights for the crossing traffic are green – and the risk for collision is considerable.

Traffic lights are normally positioned at heavily trafficked intersections and where ordinary traffic signs or right-of-way rules are not sufficient to ensure fluid traffic flow. There is therefore a statistically significant chance of driving into another road-user should a red light be neglected.


Non intrusive technology

The unique feature of SENSYS®’s radar of being able to discern distance is used to detect a vehicle passing the stop bar during the red-light phase. The red-light enforcement system, the Red Light Safety System (RLSS) is non-intrusive which means that no devices are buried in the road surface.

While a vehicle approaches the stop bar, its speed behaviour is analysed by the radar. If it is expected that a vehicle will not (be able to) stop before the stop bar, the red-light enforcement system will take a picture of the vehicle just before the stop bar, showing its position, the red light and the license plate.

If the radar detects that a vehicle is indeed passing the stop bar during the red-light phase, the red-light enforcement system will take a second picture after the vehicle has fully passed the stop bar. The second picture may be taken either by the same red-light camera from the rear, or by a second red-light camera located across the intersection. The latter option allows for driver identification should such be required by law.
