A FRAMEWORK FOR A TRAFFIC SIGNAL CONTROL SYSTEM IN A CITY

This paper describes an iteractive process for setting up a signal control system for an urban district or a whole city. Details are given of the successive steps of the process: collection of traffic data, modification of the primary system structure (i.e. intersection layouts, one-way schemes, number and position of signals, etc.) to reach the desired network capacity, further collection of traffic data, implementation of a secondary system structure (hardware and softward for signal control) which allows the most efficient use of the modified primary structure, collection of up-to-date traffic data, etc. An attempt is made at formulating a theory for control areas based on minimum generalized costs associated with traffic. An L.P. algorithm is presented for calculating the capacity of a network and examples are given of (1) a strategy, tested in Stockholm, which uses continuously variable cycle time, and (2) special control strategies for two adjacent intersections.
