Germany’s Physical Technical Institute in Brunswick has approved Jenoptik’s TraffiStar S350 laser scanner system for the German market. The scanner is a stationary speed measuring system that works without the need for piezo-electric sensors or induction loops incorporated into the road surface. Instead, vehicle speed is obtained with contact-free or non-invasive sensors.
The TraffiStar S350 can be used in road bends, unclear or obscured road situations as well as in tunnels, can distinguish between cars and trucks and it is possible to set different photo trigger limits for each lane and each vehicle class.
Error-free matching of the calculated speed and the relevant vehicle is documented by marking of the measured vehicle in the image. This marking is a frame overlaid on the image with the correct perspective. It also contains a field showing the measured speed. The system has a short measuring distance of only 10 metres. Since the distance between the end of the measuring field and the position of the vehicle at the time of taking the picture cannot be more than five metres, matching errors due to lane changes are ruled out.
The TraffiStar S350 laser scanner system is integrated into the TraffiTower 2.0 design housing specially made for this purpose. Depending on requirements, it is possible to monitor both driving directions and several lanes simultaneously, either from the side of the road or from the centre divider.
