【摘要】：为了实现公交线控最优化,在分析已有公交优先条件下线控系统相位差优化方法局限性的基础上,考虑社会车辆和公交车辆行驶车速的随机特性,将行程时间、人均延误、公交车延误、社会车延误、公交车排队和社会车排队作为线控系统运行评价指标,利用信息熵理论和多属性综合决策方法设计了线控系统相位差优化算法。最后将该算法应用于某线控系统相位差优化,利用Simio进行了仿真与结果分析。结果表明:所设计的相位差优化方法有效、可行,能获得相对较优的相位方案;在相位差的设置过程中应综合考虑各方向和各路段的车流运行特征,不同车流路段行程车速的随机特性是相位差设置的显著影响因素。
[Abstract]:In order to realize the optimization of bus line control, on the basis of analyzing the limitation of phase difference optimization method of line control system under the condition of bus priority, considering the random characteristics of the speed of social vehicles and public transport vehicles, the travel time and average travel time are delayed. Bus delay, social vehicle delay, bus queue and social vehicle queue are used as evaluation indexes of wire control system. The phase difference optimization algorithm of wire control system is designed by using information entropy theory and multi-attribute comprehensive decision method. Finally, the algorithm is applied to the phase difference optimization of a wire control system, and Simio is used to simulate and analyze the results. The results show that the phase difference optimization method is effective and feasible, and a relatively optimal phase scheme can be obtained, and the running characteristics of various directions and sections of the vehicle flow should be considered comprehensively in the process of setting the phase difference. The random characteristics of the travel speed of different traffic flow sections are the significant influencing factors of the phase difference setting.
