摘要
基于客流分布的快速公交车弹性发车间隔优化,在以往文献和IC卡刷卡数据分析的基础上推算各个公交站点到站客流分布.同时考虑不同车型最大载客量对发车间隔的影响,以乘客在站等待时间最小和公交公司运营成本最小建立公交车发车间隔优化模型.并以大连市快速公交为研究对象,利用NSGA-Ⅱ算法对研究时段内的上下行两个方向的发车计划进行优化,并取解集中值与实际发车计划进行对比.最终得出优化后上行方向的发车计划可在运营成本几乎不变的情况下,减少乘客的在站等待时间;下行方向则在保持乘客等待时间有9.4%小幅上升的情况下,节约33%的运营成本.可见优化模型可以有效地安排线路上下行两种车型的联合发车计划,提高公交的运行效率.
The optimization of bus rapid transit departure interval is conducted based on passenger flow distribution.The distribution of passenger flow of each bus station is calculatedbased on the past literature and bus IC card swipe data,and the bus departure interval optimization model is established with the minimum waiting time of passengers at the station and the minimum operating cost of company considering the impact of the departure interval on maximum passenger capacity and different bus types.Dalian BRT system is taken as the research object,and the departure schedules are optimized,calculated and compared with the actual departure schedule using the NSGA-Ⅱ algorithm in upstream and downstreamdirections during the operation period.It is concluded that the optimized upstream departure schedule can reduce the waiting time of passengers while the operating cost being almost unchanged,and the downstream direction operating costs can save 33%with 9.4%slightlyincreasedwaiting time.The optimization model can effectively arrange the line departure schedule of upstream and downstream for two kinds of bus types and also improve the bus operating efficiency.
