How SCOOT works

Information on the physical layout of the road network and how the traffic signals control the individual traffic streams are stored in the SCOOT database.

Any adaptive traffic control system relies upon good detection of the current conditions in real-time to allow a quick and effective response to any changes in the current traffic situation.

SCOOT detects vehicles at the start of each approach to every controlled intersection. It models the progression of the traffic from the detector through the stopline, taking due account of the state of the signals and any consequent queues.

The information from the model is used to optimise the signals to minimise the network delay.
