In a discussion of area traffic control systems which cover many junctions, the report considers the operation of groups of up to eight signalized traffic intersections which are linked in sequence along an urban arterial route and which are controlled by fixed-time signal plans. A method of identifying the onset of peak and off-peak traffic conditions is described through the monitoring of vehicle detector output from which appropriate signal plans are automatically introduced. Signal control algorithms are evaluated in which optimum times for initiating plan changes may be identified from the output of inductive loop vehicle detectors rather than on a fixed-time basis.
