Queue Detection

A queue occures when the traffic flow stops being synchronised and breaks down into a wide moving traffic jam or congestion. This is by itself not a safety-critical situation, but may require automated changes of signage.

Automatic responses to mitigate the queue

The Trafsense road monitoring system measures the degree of queue, which allows for automatically lowering the local speed limit, activate upstream warning signs, push warnings, etc. at a predefined degree of congestion.

Precise detection of queue location and duration

The Trafsense road monitoring system reports the percentage queue per lane with a spatial resolution of 100 m and temporal resolution of three minutes. Separate queues along the monitored road are reported individually and per lane.

Avoiding queue alarms from single slow-moving vehicles

A slowly moving vehicle that does not slow down any upstream traffic, is not defined by Trafsense as a queue as this is not safety critical information that requires any immediate human action.
