【摘要】：城市化的高级阶段带来人口和机动车的过度增长,使得城市交通拥堵严重。政府拟通过大力发展公共交通来缓解交通拥堵问题。随着区域内经济社会与公共交通的日趋成熟化发展,常规公交发展较为完善,覆盖范围较广,但运营过程中故障时有发生,一方面对公交车辆运营造成影响,另一方面也容易带来部分路段交通堵塞,引发二次事故。因此,本文对公交车辆应急救援服务点的合理配置和布局进行研究,通过利用现有资源,调配救援设施设备及人员,合理布局服务点。通过体系化地研究公交车辆应急救援服务点布局问题,以便最大程度提供良好的救援服务,提升响应速度,尽可能减轻公交车辆故障与事故的影响,对提升城市交通应急保障能力有重要意义。论文在分析国内外选址理论及相关应急救援服务理论的基础上,分析了公交车辆发生交通故障的类型、发生地点的类型、不同车型发生故障的情况,总结了公交车辆交通故障的特点,并对应急救援体系进行了评述,提出了目前我国公交应急救援体系运行现状以及存在的问题。论文通过构建相应的救援网络,确定路段路权、节点权重、网络路径,研究了公交车辆应急救援服务点选址的问题。本文对选址问题的一般模型,如覆盖模型、P-中值模型、P-中心模型等进行评估分析,结合文中服务点选址思路与原则,考虑影响选址的多个因素,构建多目标模型应用于公交车辆应急救援服务点选址问题。通过确定算法求解方案,并选取达州市公交线网作为实例进行研究,验证该理论研究应用于实际服务点选址问题的可行性,为决策者提供依据。
[Abstract]:The advanced stage of urbanization brings the excessive growth of population and motor vehicles, and makes the urban traffic jam serious. The government plans to ease traffic congestion by vigorously developing public transport. With the development of economy, society and public transportation in the region, the development of conventional public transport is more perfect and covers a wide range, but faults occur frequently in the operation process, on the one hand, it has an impact on the operation of public transport vehicles. On the other hand, it is easy to bring part of the road traffic jam, causing a second accident. Therefore, this paper studies the reasonable allocation and layout of emergency rescue service points for public transport vehicles. By utilizing existing resources, deploying rescue facilities, equipment and personnel, reasonable layout of service points is carried out. Through systematical research on the layout of emergency rescue service points for public transport vehicles, in order to provide the best rescue service to the maximum extent, improve the response speed, and minimize the impact of bus failures and accidents as far as possible. It is of great significance to enhance the ability of urban traffic emergency support. Based on the analysis of the theory of location selection at home and abroad and the theory of emergency rescue service, the paper analyzes the type of traffic failure, the type of location, and the failure of different types of vehicles. This paper summarizes the characteristics of the traffic failure of public transport vehicles, comments on the emergency rescue system, and puts forward the present operating status and existing problems of the public transport emergency rescue system in China. By constructing the corresponding rescue network, determining the road right, node weight and network path, this paper studies the location of emergency rescue service points for public transport vehicles. In this paper, the general model of the location problem, such as the covering model, the median model and the P- center model, is evaluated and analyzed. Combined with the thought and principle of the location of the service point in the paper, several factors affecting the location are considered. A multi-objective model is constructed to solve the problem of bus emergency rescue service location. By determining the solution scheme of the algorithm and selecting Dazhou bus network as an example, the feasibility of applying the theoretical research to the practical service point location problem is verified, which provides the basis for the decision makers.
