重庆373路公交运输组织优化设计

摘要随着时代的进步与经济的飞速发展，汽车保有量逐年增加，由此带来的交通管理，交通拥堵等问题迫切需要解决。公交作为交通系统的重要组成部分，具有载客量大、票价低等优点，因此大力发展公交是解决此类问题的重要途径。而合理编制公交发车时刻表是公交运营调度过程中的关键工作之一，传统的发车时刻表编制较为复杂，为了简化公交的发车时刻表编制流程，降低编制难度，平衡公交企业和乘客在发车运营过程中的利益，采用一种单线发车时刻表优化方法。该方法考虑了运营和服务平衡，建立相应的模型来计算乘客的出行成本和公交运营成本。模型中考虑了车辆到达各站时刻滞后于发车时刻的情况，根据各站点以往客流数据拟合乘客到达率函数，以整个出行系统总成本最低为目标，迭代求解出各班车发车时刻。本文以重庆373路公交晚高峰时段为例进行发车时刻表优化，优化调整后的公交发车时刻表与现状发车时刻表进行比较。结果显示，经过优化调整后的公交公司的运营成本降低了7.14%，乘客的等车时间成本降低了10.68%，整个出行系统的成本降低了8.51%。本文在考虑公交发车运营成本和乘客出行成本的同时，对提出的方法进行了定量验证，证明了该方法的可行性和有效性。关键词：公交调度：公交时刻表；迭代求解：发车时刻Optimization design of bus transportation organization of 373 Road inChongqingAbstractWith the progress of the times and the rapid development of the economy,the numberof cars in use has been increasing year by year,which has brought about urgent problemssuch as traffic management and congestion that need to be solved.As an importantcomponent of the transportation system,public transportation has the advantages of largepassenger capacity and low ticket prices.Therefore,vigorously developing publictransportation is an important way to solve such problems.Reasonable preparation of busdeparture schedules is one of the key tasks in the process of bus operation scheduling.Traditional departure schedule preparation is relatively complex.In order to simplify theprocess of bus departure schedule preparation,reduce preparation difficulty,and balance theinterests of bus enterprises and passengers in the departure operation process,a single linedeparture schedule optimization method is adopted.This method considers the balancebetween operation and service,and establishes corresponding models to calculate the travelcosts of passengers and the operating costs of public transportation.The model considers thesituation where the arrival time of vehicles at each station lags behind the departure time.Based on past passenger flow data at each station,a passenger arrival rate function is fitted,with the goal of minimizing the total cost of the entire travel system.The departure time ofeach bus is iteratively solved.This article takes the evening peak hours of Chongqing No.373 bus as an example to optimize the departure schedule.The optimized and adjusted busdeparture schedule is compared with the current departure schedule.The results showed thatafter optimization and adjustment,the operating costs of the bus company decreased by7.14%,the waiting time cost of passengers decreased by 10.68%,and the cost of the entiretravel system decreased by 8.51%.This article quantitatively validates the proposed methodwhile considering the operating costs of public transportation and passenger travel costs,proving its feasibility and effectiveness.Key words:bus dispatching;Bus schedules;Iterative solution;Departure time目录摘Abstract...III第1章绪论1.1研究背景...。11.2研究目的和意义.21.3国内外研究现状..31.3.1国外研究现状。。。。。。。。31.3.2国内研究现状41.3.3研究现状总结51.4主要研究内容51.5技术路线61.6本章小结.…7第2章公交时刻表编制相关理论概述……82.1发车时刻表定义及分类...82.1.1发车时刻表定义82.1.2发车时刻表分类82.2发车时刻表编制原则与方法92.2.1发车时刻表编制原则92.2.2发车时刻表编制方法92.3发车时刻表编制关键点1
