TUNING THE TRAFFIC MODEL

This paper examines the issues which must be considered for the successful validation of a SCOOT traffic control system. It is derived from the authors' experience in a series of SCOOT projects, including: (1) research of the model's accuracy at Southampton University; (2) installation and maintenance of Hampshire County Council's SCOOT system; and (3) design, implementation and facilities management of SCOOT systems for several clients. Before validating a SCOOT model, correct data about the street network and traffic control system must be entered. Validation procedures are detailed in the SCOOT Traffic Handbook and other documents. Good validation is essential if the SCOOT model is to represent road conditions accurately. The most important of the parameters to be validated are: (1) link journey time; (2) saturation occupancy; (3) maximum queue clear time; (4) start lag; and (5) end lag. Current SCOOT versions can 'optimise traffic management'.
