摘要
研究公交与地铁调度协同发展,以地铁客流为基准匹配接驳公交的发车间隔和运力配置等,可有效减少乘客换乘等待时间,提升公交与地铁衔接一体化效益。首先建立以乘客换乘时间和公交企业运营费用的总成本最小化为目标的运营计划优化模型,确定调度协同的综合启动阈值,通过分析接驳公交客流分布特征,初步制定各接驳公交晚高峰时段的发车时刻表;其次以满载率等为约束条件,确定初始车型建议,得到初始的调度协同方案;最后对线路的满载率分析,对于存在满载率过高或过低的线路调整发车间隔和车型配置,得到最终的公交与地铁调度协同方案。研究结果有利于解决广州市目前公交与地铁换乘时间过长问题,提高接驳公交的吸引力和竞争力。
The coordinated development of bus and subway dispatching,matching the departure interval and model configuration of connected bus based on subway passenger flow can effectively reduce the waiting time for passenger and improve the integration efficiency between the bus and the subway.Firstly,an operational optimization model aiming at minimizing the passenger’s transfer time and the total cost of bus operation is established,and the comprehensive threshold of dispatching coordination is determined.By analyzing the distribution characteristics of the passenger flow of connected bus line,the initial departure timetable of connected bus at the peak rush hour is made;Secondly,determining the initial model proposal with the full load rate as the constraint,and getting the initial dispatching coordination plan;Finally,analyzing the full load rate of the bus line.If the full load rate is too high or too low,adjusting the departure interval and model configuration to get the final bus and subway dispatching coordination plan.This study is conducive to solving the problem of excessive transit time of public transportation and subway in Guangzhou,and improving the attractiveness and competitiveness of public transportation.
