Many drivers see the yellow light as a sign to speed up instead of to slow down. Traffic signals are often placed at busy intersections to protect all road users: drivers, cyclists and pedestrians. Those people who run red lights, therefore, pose a huge risk. Despite local authorities redesigning intersection layouts or adjusting the yellow phase, each year there are hundreds of thousands of accidents and several thousand deaths as a direct result of red light running. As an extension of traffic safety schemes, it is possible to further minimise intersection accidents by using red light enforcement cameras. PoliScanredlight is the world’s first laser-based non-invasive red light system which has been solely designed to enhance road user safety.
    
LIDAR technology
PoliScanredlight was officially launched at the ITS World Congress in Stockholm. It is based on Light Detection and Ranging (LIDAR) technology which scans the entire road area multiple times a second. In comparison with traditional radar enforcement systems this laser measurement allows the system to build up an accurate image of the current traffic situation. Up to 3 lanes can be enforced from a single system. Lane-specific detection allows violations to be attributed to a vehicle traveling in a pack. As a result drivers traveling parallel, overtaking, tailgating or changing lanes are all captured. The non-invasive system requires no loops in the road, reducing costs and disruption to traffic flows. The reason for this is the virtual stop line created by the LIDAR technology.
    
Unique system
If the light is red and the vehicle crosses the virtual stop line (i.e. a violation occurs) digital cameras are instructed to capture the scene. In a normal scenario two images are captured: the first is of the vehicle crossing the stop line and the second is of the vehicle in the middle of the hazard area. Depending on local regulations the photos can be either taken from the front or the rear and can be colour or black and white.
    
The PoliScanredlight system is installed in a unique housing which blends perfectly into any urban environment. The housing not only looks different from any other red light enforcement system on the market but also permits various installation options. The bullet-proof aluminum pillar is made up of independent segments which can be angled to suit the traffic direction. Two systems can be inserted into a housing which allows two different traffic approaches to be monitored. Each system can enforce up to three lanes of traffic meaning up to six lanes can be captured from a single point. A PoliScanredlight system comes with a local storage module meaning that if the system is moved to another location and then back to its original site, this is automatically recognised and the system reinstalls itself. In addition to red light enforcement PoliScanred+speed also provides permanent automatic speed enforcement (on red and green), capturing vehicles travelling in excess of 250km/h.
