In recent years there has been considerable emphasis on traffic management schemes in town centres. To co-ordinate control of signals over a wide area is one such traffic management scheme which will produce benefits where the density of signals in an area is relatively high. It became evident in Leicester that as the number of signalised junctions in the city increased, some form of co-ordinated control would be required if the maximum capacity was to be obtained from them. Currently there are 94 signals in the city with an average density of 15 per square mile. This paper describes the traffic engineering design, the system components and the equipment used in the area traffic control system, which is now operational (October 1974). A brief account is also given of the operational software used with the system. Plans for the extension and development of the system, and other possible applications are briefly discussed. /TRRL/
