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。
In order to realize the optimization of the bus line control, based on the analysis of the limitation of the phase difference optimization method of the line control system under the bus priority, the stochastic characteristics of the traveling speed of the social vehicle and the bus are considered, and the travel time, per capita delay, Delay, social vehicle delay, bus queuing and social vehicle queue as the evaluation indicators of the operation of the wire-controlled system, the information-entropy theory and the multi-attribute integrated decision-making method are used to design the phase difference optimization algorithm of the wire-controlled system. Finally, the algorithm is applied to the phase difference optimization of a line control system. Simio is used to simulate and analyze the results. The results show that the designed phase difference optimization method is effective and feasible and can obtain a relatively optimal phase scheme. In the process of phase difference setting, the traffic flow characteristics in all directions and in each section should be considered comprehensively, and the travel speeds of different sections Features are significant contributors to the phase difference setting.
