Can Traffic Radar Measure Queues Reliably?
A detector can report every approaching vehicle correctly and still fail the junction if it cannot identify the back of a queue. That distinction matters at congested urban approaches, signalised roundabouts and temporary traffic-management sites, where delayed queue...
Intersection Presence Sensors for Better Signal Control
A signal stage can only perform as well as its knowledge of the traffic waiting for it. When a vehicle is missed at the stop line, held in a turn lane or waiting at a side-road approach, the result may be wasted green time, unnecessary delay or a safety-critical...
Traffic Sensors for Smarter, Safer Road Networks
A detector failure at a busy junction is rarely visible from the control room, but its effects are immediate: missed calls from cyclists, unnecessary green time, queues extending into adjacent links and frustrated road users. Modern traffic sensors give highways teams...
How Do Radar Detectors Work on Modern Roads?
A detector that misses a waiting cyclist, holds a green phase for an empty approach, or requires a lane closure to repair can have a direct effect on network performance. That is why the question, how do radar detectors work, matters well beyond simple speed...
