快速公交线路发车频率优化仿真研究

该文在阐述公交发车频率与乘客等车时间、公司盈利之间关系的基础上,分析快速公交线路站点时段客流规律、构建乘客等待时间和公司运营收益模型,提出基于乘客等待时间最小、公司盈利最大的快速公交发车频率多目标函数,并设计遗传算法和优化仿真实验。仿真实验表明:一定范围内,发车次数增加,乘客的总等车时间和BRT运营收益反而逐渐减少,而本函数模型能有效地降低运营成本、节约乘客等待时间,比按客流比例发车的结果更优化。研究成果应用于大同市快速公交线路工程实例。

Study on Optimizing Simulation of Bus Rapid Transit Schedule

Based on setting forth the relationship of bus rapid transit(BRT) schedule and passenger waiting time and company profit,the article analyzes the different-time passenger traffic law of BRT station and establishes the model of passenger waiting time and company operating earnings,puts forward the multi-objective function of BRT Schedule on the minimum waiting time of passengers and the maximum company profit,and designs the genetic algorithm and optimizing simulation experiments.The simulation experiment sh...
