Inductive loop technology has been widely used over many years to count and classify traffic flows. Its major deficiency is that any work on the loop requires the lane or road to be shut thereby creating delays.
Both Video and Bluetooth are above ground technologies which can also count vehicles, measure headway, speed etc. to provide virtual loops.
Our video based solutions include both smart video sensors, where the processing is done roadside and only management data needs to be transmitted, and centralised systems where existing CCTV infrastructure running back to a traffic control centre can be used as the sensor. This makes for a dual use of the CCTV camera network, significantly enhancing its value.
