URBAN TRAFFIC CONTROL - THE NEXT FIVE YEARS

This paper outlines some areas of future development for urban traffic control (utc). Such developments include the following adaptations: (1) a version of SCOOT (split cycle offset optimization technique), an adaptive system that has predetermined instructions to be obeyed when congestion is detected; (2) systems that combine both utc and remote monitoring unit (rmu) functions which can be run on microcomputers using the user friendly software already available; (3) rmu systems with added utc control. These 'dial-up' systems allow fixed time plans to be sent from a central system to local traffic signal controllers on an occasional basis; (4) standardisation of current utc data transmission systems, giving more choice in equipment and communications medium. Implications of the future widespread use of route guidance systems, and the sharing of data communication links with utc systems. The implications for utc are also considered for light rail transit (lrt). For lrt systems, which run on city centre streets and which use signalled controlled junctions, priority can be given utilizing bias signal timings. This factor must be considered in the design of lrt systems.
