城市轨道交通Y型线路列车运行交路的研究-交通运输规划与管理专业毕业论文.docx

摘 要
随着我国国民经济的发展,国家城镇化速度的加快,近些年来由于城市建设和发展的需要,大量的农村人口进入了城市及城市原有人口的增加,使得大城市尤其是特大化城市数量不断的增加。大城市尤其是特大城市由于机动车数量逐年的增加和城市人口出行量的增加,当城市道路的建设跟不上城市发展需求时,城市交通拥堵问题就出现了并且越来越来严重。城市交通的拥堵问题成为了制约城市发展的重要因素。城市交通的发展迫切需要运量大、能耗低、安全可靠、简单便捷的新型交通工具来缓解道路拥挤问题。在这样的背景下,我国大型城市清楚的意识到只有发展城市轨道交通系统才能有效的缓解目前城市道路拥堵问题,才能使城市经济可持续发展。城市轨道交通网络的建设以及后期的运营管理具有连续性。它既区别于国有铁路系统又区别于城市公交系统。如何使城市轨道交通系统高效的运转,更好的服务于居民的出行,就成为城市轨道交通领域研究的热点问题。
本文在分析了国内外城市轨道交通列车交路方案研究的基础上。针对城市轨道交通线路发展中由单一线路逐渐发展到网络化线路出现的线路交叉所形成的轨道交通 Y 型线路的交路方案进行研究。介绍了轨道交通常见交路的形式,分析了轨道交通 Y 型线路形成的原因以及影响因素和交路方案。最后在 Y 型线路列车交路方案的研究过程中通过对交路方案的主要影响因素比选分析,确定了以旅客满意度及单位运营成本为目标函数,以线路列车开行间隔为线路间匹配关系的优化模型,将多目标规划问题转化为单目标规划问题进行了求解。

Abstract
With the development of economy, the urbanization speeds rapidly in China. In order to meet the requirement of urban construction a large number of rural people move into the cities, as well as the urban population grows what makes the number of city increase, especially for large city. As the number of motor vehicles and population in these cities increase day by day, urban traffic congestion problems have emerged and e more and more serious when the construction of urban roads can not keep up with demand for urban development, which restricts the development of city. The urban traffic development needs new transport that has the characteristics of Large volume, low energy consumption, safe, reliable, simple and convenient. Basing on such background, people realize that Developing urban rail transit system is the only way to solve the problems, as well as to achieve the Sustainable development of urban economy. The construction of urban rail work and post- operational management is continuous, differing from state-owned railway system and urban public transport systems. The research in urban mass transit would be wildly concerned if related system operates well.
This paper analyzes the Y-line routing plan of rail transit that gradually changes from single line work line in the development of ra
