Optimizing networks of traffic signals in real time-the SCOOT method

The evolution of the SCOOT urban traffic control system from research by the British Government's Transport and Road Research Laboratory on the TRANSYT method of optimizing networks of fixed time signals is described. The key principles of the SCOOT online traffic model and real-time signal optimizers are explained. The results of surveys on the effectiveness of SCOOT are reviewed, applications are summarized, and some recent developments are outlined.<
