The computer simulation of optimum signal setting at Saladaeng Intersection has been organized into two parts. The first was a field experimental study. By using a cine camera, the traffic demands and the operating characteristics of the intersection were obtained, The second part was the development of a computer simulation model. The program was written macroscopically using the cycle length as the scanning period. The optimum cycle length was found through simulation after the validation of the model by field data. It was determined that 145 sec and 175 sec would be the most suitable cycle lengths for the morning and the evening peak traffic periods, respectively. The optimum signal setting would reduce the average vehicular delay from that produced by the police-controlled, long-cycle length operation ordinarily used during the peak-hour periods.
