The detector is mounted above the red aspect and pointed towards the oncoming traffic. The detector has a single zone of detection stretching from the radar to typically 35m along the carriageway. The detection zone is such that only vehicles approaching the detector are detected and vehicles travelling away from the detector are ignored. Up to two lanes wide can be monitored.
