The program has as its ultimate objective the investigation of new strategies for improving traffic control in congested urban areas. The investigation will be performed by using a digital computer and a network of vehicle detectors to analyze traffic parameters and select timing patterns for the traffic signals in a 200-intersection area of Washington, D.C. This on-street testing approach to the urban traffic problem has been initiated because the alternative techniques of analysis and simulation have not yet led to significant improvements in traffic control. The objective of the Advanced Control Technology study phase of this program was to define the traffic control system in sufficient detail for estimating costs, purchasing and installing equipment, and programming the computer for basic on-line control. The major tasks performed in meeting these objectives were: (1) establishing traffic parameters to be used as the basis for on-line selection and evaluation of control strategies, (2) developing concepts for a traffic signal control system which can readily implement experimental control strategies, (3) defining equipment configurations and operator's functions, (4) generating installation and maintenance plans, (5) generating software and equipment specifications, and (6) testing loop vehicle detectors.
