A trial of TrafiCam video vehicle detection was carried out by TRL for the Department for Transport at a test site in Winchester. Trial detectors were mounted on a lamp column located next to a SCOOT loop (Split Cycle Offset Optimisation Technique), so the output from the video detector could be compared to a traditional induction loop sensor within the surface of the road, in terms of its effectiveness for detecting traffic approaching signal-controlled junctions.

The TrafiCam was found to produce very similar output to the configured induction loop, even when mounted 4-5m above ground.  The trial proved that video detection can be used instead of induction loops for vehicle detection at junctions.  It has the benefit of easy installation and maintenance because it is not buried in the road surface like an induction loop.  The product will be marketed as a suitable detector for SCOOT and Microprocessor Optimised Vehicle Actuation (MOVA) applications.
