Traffic queue detection from a standard road camera
See when traffic starts backing up on a stretch of road or highway — how far back it reaches, how many vehicles are in it, and an alert before it blocks a junction or off-ramp.
Demo result: caught a queue forming at a red light and followed it to 89 m and 26 vehicles. 46 of 186 vehicles were delayed, by 28 seconds on average. Alerts fired at 40 m and 75 m.
How it works
- You choose the stretch of road to watch.
- Every vehicle is detected, tracked and its speed measured.
- The camera calibrates itself from passing traffic, so no site survey is needed.
- When stopped or slow vehicles chain together, the system reports the queue length in meters and raises alerts at the distances you set.
Who it's for
Traffic management centers, highway operators, work zones, and junctions where queues cause crashes or gridlock.
Questions
Does it need sensors in the road?
No. It uses a standard traffic camera and calibrates itself from the passing vehicles.
How far can it see?
Accuracy is best within roughly 120 meters of the camera; beyond that, a second camera is recommended.
Can it work at night?
With adequate street lighting, yes. For dark roads, a thermal camera can be used instead.
