Vitronic to launch new red light enforcement system at ITS World Congress

Wiesbaden, Germany-based Vitronic will be launching its PoliScanredlight system at the 16th World Congress on ITS in Stockholm next week. This new development is the only fully automated laser-based red light enforcement system worldwide, which can operate without the need for in-road equipment, such as loops or piezo sensors. Eliminating invasive equipment has several advantages, including reduced costs and a decrease in traffic flow disruption as the systems are installed and maintained. 

PoliScanredlight is based on the same LIDAR (laser) technology as the company’s PoliScanspeed enforcement system. The measurement unit scans the complete road area many times a second to build up an accurate image of the traffic scene. Using a ‘virtual stop line’ it can enforce up to three lanes of traffic. When two measurement units are used, two different traffic approaches can be monitored from a single location. Drivers traveling parallel, tailgating or changing lanes at intersections are all captured.

If a driver is caught driving through a red light, two digital photographs of the vehicle are taken – one of the vehicle crossing the stop line and another when the vehicle is in the middle of the hazard zone. These images are then stored along with other case data, and the case file is digitally signed to prevent data manipulation. Encryption of the data allows its secure transfer to the back-office for further processing. Using a remote camera, photographs of the rear of vehicles can also be taken.

The PoliScanredlight LIDAR unit can also be upgraded to provide combined speed and red light enforcement. PoliScanred+speed operates in the same way, but also offers permanent speed enforcement, whether the lights are red or green. The system can capture vehicles traveling at speeds in excess of 250km/h irrespective of the time of day, weather conditions or traffic density.
