'STRUCTURE' IN INTERSECTION CONTROLLERS

The structure in an intersection controller is described as what the traffic engineer can define, strategy is what the controller does automatically. Strategies of control for local isolated intersections are discussed with examples. The type of strategy and the model which works with it are largely determined by the electronics technology available. The structure should be such that manual programming is possible and it should be capable of being actuated by strategy using detector inputs, time-selective fixed-time plans or by remote control. The examples chosen to illustrate the structures include a very simple traffic controller, the current standard UK method of control, the us dual-ring structure and a block structure. The traffic engineer needs enough flexibility in the structure to be able to incorporate priority operation for buses, emergency vehicles, pedestrians, cyclists and other particular users. A standard signal installation specifying form is described which can be used to exploit a strategy and structure combination. (TRRL)
