Optimization Algorithm of Real-Timing Signal Control for Isolated Intersections

Abstract:

To make full use of green time of each phase to alleviate congestion in urban isolated intersections, an optimization algorithm of real-timing signal control is proposed. By monitoring traffic flow at the isolated intersection, the average utilization rate of green time of each phase is calculated. The green time of each phase is then adjusted automatically to maintain a balanced green time utilization rate with the presented optimization algorithm. Simulation results indicate that the average delay and the queue length of the presented algorithm are less than the fixed-time signal plan at peak times, and the efficiency of the intersection traffic is improved.
