Operation Research and Mathematical Modeling of Real-Time Signal Traffic Cycle Optimization in Ho Chi Minh City of Southern Viet Nam

This paper presents a method of mathematical modeling for optimal determine the real time signal setting (RTSS) the cycle in order to reduce congested situation. Bases on the rate flow, the traffic density on the line, the intersection capacity and linking to near intersections as well, in order to compute the cycle more accurately. The result was assessed and compared to current traffic situation in some streets in Ho Chi Minh City of Southern Viet Nam. The results show that RTSS model can applying in real-life intersections, the clearing time and length of queue reduce over 90% compared with current signal cycle.
