【摘要】：城市群城际铁路是在城市群城市节点间承担大规模旅客运输的重要交通方式。由于建设费用高、建设周期长、经济和社会成本较大,城际铁路建设需要制定分阶段实施的建设时序规划。合理的城际铁路线路建设时序不仅可以在有限的资金资源条件下尽可能好地满足城市群城际铁路出行需求、提高旅客出行的便捷性、增强城际铁路在城市群的可达性、发挥城际铁路客运骨干作用,还能更好地适应城市空间发展、促进产业交流、避免资源浪费、提高城际铁路的经济性,实现城际铁路价值。论文从规划的角度,提出城市群城际铁路线网建设时序决策方法,以期为城际铁路建设时序决策提供参考。首先,对研究对象进行界定。论文收集了城际轨道交通相关文献,界定了城市群城际铁路概念,明确了城际铁路的功能定位和在城市群综合交通运输系统中的作用。其次,对研究内容进行说明。结合城市群城际铁路建设的技术经济特性,从结构适应性、经济适应性、需求适应性三个角度确定建设时序决策准则,明确城际铁路建设时序研究的基本内容。再次,基于前文关于建设时序决策准则的研究,论文从线路结构完备性、线路空间适应性和线路需求匹配性三个方面入手,以这三个方面最优为目标函数,在有限建设资金资源的约束下,构建多目标规划模型,综合考虑到城际铁路客流均衡,进行不同阶段下的城际铁路线路建设时序研究,并应用遗传算法进行求解。其中,线路结构完备性考量内容包括城际铁路网络可达贡献度和客流集散点覆盖度,线路空间适应性考量内容包括沿线城市综合关联度和沿线产业综合关联度,线路需求匹配性考量内容包括线路客流匹配性以及在此基础上的线路投资回报程度。最后,以成渝城市群为例进行建设时序研究,验证研究内容可行性。
[Abstract]:Intercity railway in urban agglomeration is an important mode of transportation for large-scale passenger transport among urban nodes in urban agglomeration. Due to the high construction cost, the long construction period and the large economic and social cost, the construction of inter-city railway needs to be carried out in stages. Reasonable timing of inter-city railway line construction can not only meet the needs of intercity railway travel in urban agglomeration, improve the convenience of passenger travel, but also enhance the accessibility of inter-city railway in urban agglomeration under the condition of limited capital resources. Exerting the backbone role of inter-city railway passenger transport can better adapt to the development of urban space, promote industrial exchange, avoid the waste of resources, improve the economy of inter-city railway, and realize the value of inter-city railway. From the point of view of planning, this paper puts forward a method of timing decision for the construction of intercity railway network in urban agglomeration, in order to provide a reference for the timing decision of inter-city railway construction. First of all, the research object is defined. This paper collects the related documents of intercity rail transit, defines the concept of intercity railway in urban agglomeration, and clarifies the function orientation of intercity railway and its function in the integrated transportation system of urban agglomeration. Secondly, the research content is explained. Combined with the technical and economic characteristics of inter-city railway construction in urban agglomeration, the construction timing decision criteria are determined from three aspects of structural adaptability, economic adaptability and demand adaptability, and the basic contents of the research on the timing of inter-city railway construction are clarified. Thirdly, based on the previous research on the decision criterion of construction time sequence, this paper starts with three aspects: the completeness of the line structure, the adaptability of the line space and the matching of the line requirements, and takes these three aspects as the objective function. Under the constraint of limited construction capital resources, a multi-objective programming model is constructed. Considering the inter-city railway passenger flow equilibrium, the time sequence of inter-city railway line construction in different stages is studied, and the genetic algorithm is applied to solve the problem. Among them, the content of line structure completeness includes the reachable contribution degree of inter-city railway network and the coverage degree of passenger flow distribution point, the content of line spatial adaptability consideration includes the comprehensive correlation degree of city along the line and the comprehensive correlation degree of industry along the line. Line demand matching includes line passenger flow matching and line investment return on this basis. Finally, taking Chengdu-Chongqing urban agglomeration as an example, the construction time series is studied to verify the feasibility of the research.
