The specifications for the laser system were drawn up by TCT.
 +
The system software was developed by local company Radar Vision, which sourced the laser from Europe.
 +
The sensor is a Class 1 laser device that emits infrared light invisible to humans and has an operating temperature range of -10C to 70C.
 +
The system scans the roadway 50 times per second, taking a measurement every 0.5 degrees. The sensor reports distance in millimetres for each measurement.
 +
The road is 6,600mm vertically below the sensor, while traffic with a height above 500mm from the road surface is recognised.
 +
The sensor measures vehicles up to 5.8m in height, and 8.5m of the road’s width.
 
The system controller does all the calculations to determine which lane every detected point is in.
