AREA TRAFFIC CONTROL IN LEICESTERSHIRE

This article describes the wide area traffic control system which has been installed in Leicester to control the complete city's traffic flow from one central office. The objects of the system are to minimize journey time by co-ordinating traffic signals (but still allowing for alternative plans favouring public transport or special vehicles) and the provision of a continuous and automatic signal fault monitoring system. An outline of the method of operation is given which uses a Honeywell computer and the Transyt program. Automatically selected plans (each junction can have as many as 20) will cater for the majority of traffic patterns, but the operator can over-ride the automatic system if necessary or can alter the timings at junctions. Special detector units are used to monitor traffic supplemented by 12 closed circuit television systems. The article includes a summary of contract details (the overall cost was 524,000 pounds) & future developments are discussed. /TRRL/
