COMPACT URBAN TRAFFIC CONTROL. 1. THE "CHIPS" COME TO TOWN: PREPARING FOR COMPACT UTC AND USING IT

This, the first of a series of four articles, describes the concept and operation of compact utc which is an integrated circuit system of off-the-shelf packages, intended for medium urban areas controlling 10 to 70 signalled junctions. The author discusses the preparation of a basic highway network by comprehensive traffic management means, and its interaction with the application of traffic control strategies by utc systems. Details are given of the influence of compact utc on the four approaches used: (A) the application of comprehensive management in the area; (B) the influence of patterns over a wide area to avoid concentrations; (C) the modification of demand over a wider area to ease conditions at the centre; and (D) the provision of a further infrastructure co-ordinated with a comprehensive approach. The designs of several individual control plans for typical changes in traffic patterns are discussed. The overall effect of traffic management and control is examined in terms of the cost effectiveness of various measures. The possible incorporation of dynamically reactive control programs (such as TRRL's scoot) in compact utc is considered. (TRRL)
