Comments are made on the philosophy behind baghdad's urban traffic control system. A review of the present, Stage 1, system is made and methods of vehicle detection, communication, types of local controller and traffic signal hardware are investigated. Some of the advantages and disadvantages of Stage 1 are listed i.e. the hardware is highly modular leading to easier maintenance, though all the processors are purpose built with a rigid software structure. The present Philips system couuld not incorporate directly a traffic-adaptive method of coordinating signals such as SCOOT, and there is consequently limited flexibility for adapting to likely changes in Baghdad in the future. The overall objective of the control system is to gain the most efficient use of the urban road system over a period of time. The development of a central area model is recommended based initially on traffic survey data and utilising data from the system monitoring as it becomes available. An action program is presented to ensure the overall traffic system works most efficiently. For abstract of part 1 see TRIS 381172. (TRRL)
