A SYSTEMS APPROACH TO THE AREA TRAFFIC CONTROL OF A CITY

With the rapid growth in the flexibility and sophistication of electronic integrated circuits and programmable devices the constraints in engineering have moved from hardware to application ingenuity. This is particularly true in the traffic control arena where the use of micro-computer controllers now dominates new intersection installations. In cities where signal controllers from a variety of sources have been deployed over half a century the logistics of integrating such a spectrum of technologies into an area control scheme is not a trivial task. Fiscal limitations and the improbability of realizing an immediate change in field hardware pose further constraints. This paper outlines a systems engineering approach to the problem. Consideration is given to ensuring the flexibility and expandability of equipment particularly to the development of technological bridges such that the ideosyndronics and the past practices exploited in obsolete equipment are not constraints to future operations. A plan is outlined by which means an orderly update can proceed from essentially isolated intersection control to an area co-ordinated system incorporating active public vehicle priority. (TRRL)
