Laser Technology ‘looks-down’ for traffic data collection
First publishedin ITS World Congress
Laser Technology is exhibiting a twin laser/fourcamera ‘look-down’ system that can count and profile vehicles into a number of categories as well as measure speed and the headway between vehicles. The unit, which is mounted beneath motorway gantries, contains forward and rear facing CCTV and ANPR cameras and is said to provide accuracy of 2cm even when vehicles are travelling at speeds of 120km/h.
In comparison to side fire lasers, the single-lane look-down configuration is claimed to offer better vehicle definition.
