【摘要】：近年来,随着我国城市规模和城市公共交通系统的迅猛发展,城市居民的出行方式由以往的单一模式转化为多方式共存。城市轨道交通发挥充分作用必须依靠地面常规公交的配合与协调,因此,只有大力发展功能完备、协调配合的城市公共交通系统,尤其是城市公共交通网络末端的社区微循环公交线路,才能吸引城市居民出行转向公共交通,实现真正意义上的公交优先。本文对社区微循环公交线路路径优化问题进行了研究。首先表述了公交线路的相关特性,并对社区微循环公交线路的概念进行阐述,同时分析了社区微循环公交线路路径优化问题的优化目标和约束条件。针对既有的成熟交通小区,基于乘客、公交企业、社会这三个角度,建立了单条社区微循环公交路径多目标优化模型;针对新建的未成熟的交通小区,本文引入公交开行潜在客流这一指标,建立了以公交运营企业的运营效益最大化和运营成本最低化为优化方向的多目标函数,探索交通小区内微循环公交线路集的优化求解问题。同时,根据模型所需的数据,建立了数据筛选体系和操作流程。之后,运用搜索优化算法和最短路径法求解单条社区微循环公交线路路径优化问题并通过实例加以论证;运用改进的遗传算法求解社区微循环公交线路集路径优化问题并通过模拟算例加以验证。仿真结果表明论文所提出的模型和方法具有合理性和可行性。论文旨在通过社区微循环公交线路路径优化理论和方法的研究,构建符合实际需求的社区微循环公交线路,以更好地解决社区内乘客"最后一公里"的出行问题。
[Abstract]:In recent years, with the rapid development of urban scale and urban public transportation system, urban residents' travel mode has changed from a single mode to a multi-mode coexistence. Urban rail transit plays a full role must rely on the ground routine bus coordination and coordination, therefore, only vigorously develop a well-functioning, coordinated urban public transport system, Especially the community microcirculation bus lines at the end of urban public transport network can attract urban residents to turn to public transport and realize the real public transport priority. In this paper, the route optimization of community microcirculation bus route is studied. Firstly, the related characteristics of public transport lines are described, and the concept of community microcirculation bus lines is expounded. At the same time, the optimization objectives and constraints of the route optimization of community microcirculation bus lines are analyzed. Aiming at the existing mature traffic district, based on the three angles of passengers, public transport enterprises and society, the multi-objective optimization model of single community microcirculation bus path is established. This paper introduces the index of the potential passenger flow of the public transport bank, and establishes a multi-objective function in which the maximization of the operation benefit and the lowest operating cost of the public transport operation enterprise are taken as the optimization direction. This paper explores the optimization problem of microcirculation bus line set in traffic district. At the same time, according to the data needed by the model, the data filtering system and operation flow are established. After that, the search optimization algorithm and the shortest path method are used to solve the route optimization problem of single community microcirculation bus line, and an example is given to prove it. The improved genetic algorithm is used to solve the route optimization problem of community microcirculation bus lines and verified by a simulation example. The simulation results show that the proposed model and method are reasonable and feasible. Through the research on the theory and method of the route optimization of the community microcirculation bus route, the paper aims to construct the community microcirculation bus route which meets the actual needs, so as to solve the "last kilometer" travel problem of the passengers in the community.
