CONTROL OF CONGESTION AT HIGHLY CONGESTED JUNCTIONS

The results are reported of experiments in Bangkok designed to test fixed-time signal control as a replacement for manual police control at highly saturated junctions with flows of up to 15,000 vehicles per hour. Data collection methods, use of video techniques, analysis procedures, and resulting traffic-junction performance parameters are described. The results demonstrate that it is possible to replace police control at such junctions, and that at linked junctions substantial savings in travel time can be obtained. However, existing computer-based techniques do not readily produce optimum control strategies, and additional work is needed to enable them to do so. The problems caused by substantial fluctuations in demand and in operating conditions are discussed, and proposals for further work are outlined.
