单点定时信号配时的多目标优化模型
Multi-objective Optimization Model for Signal Timing of Signalized Intersection
摘要
Abstract
To improve efficiency and robustness of fixed time signal control, the paper establishes an adjustable multi-objective optimization model to optimize signal timing. The objective function consists of two sub-targets, of which the first sub-target including three indicators such as average delay, number of stops, traffic capacity is to optimize efficiency, and the second sub-target is to optimize stability of signal control by minimizing standard deviation of vehicle delay. Based on simulation and analysis of intersections under various traffic conditions, the study establishes the relationship between sub-target weights and flow fluctuating ranges. This paper uses genetic algorithm to solve it. Results show that the multi-objective optimization model reduces the average delay of vehicles and controls maximum delay effectively.关键词
