【摘要】：随着近年来国民经济取得长足发展,城市化率不断提高,越来越多的人开始往城镇聚集。在城市的空间布局和发展成型过程中,必然绕不开城市公共交通系统这个概念。对于城市公共交通系统中最重要的两部分轨道交通与常规公交来说,随着轨道交通建设力度的持续增大,与常规公交之间的竞争关系已经越来越明显。如何协调两者之间的关系,发挥各自优势良性运营,满足居民日益增长的出行需求已经成为现今城市交通问题的重中之重。通过确立轨道交通在城市居民出行中的运送主导地位,合理规划常规公交网络作为客流的辅助运送方式,形成运行良好的接运系统,可以有效缓解城市道路交通压力。论文首先详细阐述了轨道交通与常规公交的发展概况,对两者的技术特性、经济效益特性、舒适度特性、可达性、机动性做了分析比较,根据对比结果,确立了轨道交通的主导地位。在此基础上,确定了轨道交通直接与间接客流吸引范围的大小,介绍轨道交通间接客流的来源。其次,研究了接运公交起讫点的确定以及起讫点布设的规划原则。最后,以居民最小出行时间构建模型,确定接运公交的最优站距,分析了中间站设置的规划原则。结合城市道路实际情况,分析了接运公交线网优化的思路与原则。总结了接运线网规划时涉及到的单线路与整体线网约束条件。在此基础上,提出了对现有接运公交线网的优化调整方法和实施措施,采用“逐条布线,优化成网”的方法对接运线网实行优化,以居民社会出行总时间最小以及站点接运效率最高为目标函数建立优化模型,并通过遗传算法进行求解。最后,结合苏州轨道交通1号线及常规公交运营现状,确定了轨道交通接运站点,并对轨道交通吸引范围内的接运公交提出了调整建议。
[Abstract]:With the rapid development of the national economy in recent years and the increasing rate of urbanization, more and more people begin to gather in cities and towns.In the process of urban spatial layout and development, the concept of urban public transportation system is inevitable.For the two most important parts of urban public transport system, rail transit and conventional public transport, with the continuous increase of rail transit construction, the competition between rail transit and conventional public transport has become more and more obvious.How to coordinate the relationship between the two, give full play to their respective advantages of benign operation, to meet the increasing travel needs of residents has become the most important urban traffic problem.By establishing the dominant position of rail transit in urban residents' travel, rationally planning the conventional public transport network as the auxiliary transportation mode of passenger flow and forming a well-functioning transportation system, the urban road traffic pressure can be effectively alleviated.Firstly, the development of rail transit and conventional public transport is described in detail. The technical characteristics, economic benefits, comfort, reachability and mobility of the two systems are analyzed and compared.Established the dominant position of rail transit.On this basis, the attraction range of direct and indirect passenger flow of rail transit is determined, and the source of indirect passenger flow of rail transit is introduced.Secondly, the determination of the starting and ending point and the planning principle of the starting and ending point are studied.Finally, the optimal station distance is determined with the minimum travel time of residents, and the planning principle of intermediate station is analyzed.Based on the actual situation of urban roads, the train of thought and principle of bus network optimization are analyzed.In this paper, the constraints of single line and integral network in connection network planning are summarized.On the basis of this, the paper puts forward the optimization adjustment method and implementation measures of the existing bus network, and adopts the method of "wiring one by one, optimizing the network" to optimize the connection network.The optimization model is established with the objective function of minimum travel time and the highest efficiency of station connection, and the optimization model is solved by genetic algorithm (GA).Finally, according to the current operation situation of Suzhou Rail Transit Line 1 and conventional public transportation, the rail transit station is determined, and the adjustment suggestions are put forward for the bus transportation within the attraction scope of rail transit.
