THE EFFECT OF AN INCIDENT IN A SCOOT SYSTEM - IN SIMULATION AND ON-STREET

Comparisons of traffic strategies normally take place during "traffic" traffic conditions when unusual incidents are absent. An adaptive urban traffic control (utc) system, such as SCOOT, should have benefits over a fixed-time utc system during an incident. This paper uses simulation to explore the effects of an incident on fixed-time and on SCOOT utc systems, showing the large benifits which can be obtained by an adaptive system. In February 1983 a real incident caused the closure of a major arterial in an operational SCOOT network in Coventry. The data from the incident are used to compare the SCOOT response with that to be expected from a fixed-time system. (Author/TRRL)
