城市道路网与轨道交通线网形态的关系研究

Research on the Relationship between Urban Road Network and Rail Transit Line Network

研究目的:近年来,各大中城市持续大力推进城市轨道交通建设,线网规划是指导城市轨道交通近期建设和长远发展的重要依据。城市道路是城市轨道交通的载体,沿线公交客流是未来同向轨道线路的客流基础。为全面认识城市道路网形态和轨道交通线网形态的关系,为城市轨道交通线网规划提供参考,本文梳理二者的形态,对二者的关系进行分析,并重点对棋盘型路网、放射型+环形路网城市中轨道交通线网布设的要点进行理论方面的探索。研究结论:(1)城市轨道交通线网与城市道路网形态存在一定的相似性;(2)棋盘型、放射型、棋盘+环形、放射型+环形线网是经常被应用的轨道网形态;(3)棋盘型路网本身的换乘功能较强,故只有当环形客流发达时才考虑棋盘型+环形轨网的布设;(4)放射型+环形线网的换乘点往往形成多边形,应注意多边形位置的合理性,并注意优化换乘线路组合,以减少换乘次数,提高路网的通达能力;(5)本研究成果可在实践中指导城市轨道交通线网布设,并能在具体城市轨道交通项目中实际应用。

Research purposes： In recent years, large and medium cities continue to promote the construction of urban rail transit vigorously, line network planning is an important basis for guiding the construction of urban rail transit and long -term development. Urban road is the carrier of the urban rail transit, bus passenger flow along the road is the basis of the line in the same direction in the future. In order to understand the relationship between the form of urban road network and rail transit line network, to provide some references for the urban rail transit network planning, the paper summarized the form of two sides, analyzed the relationship of each other, and emphasized on the key points of the layout of the rail transit line network in the checkerboard type road network and radial ＋ ring road network in theory. Research conclusions：（ 1 ）Urban rail transit network and urban road network has some similarity;（ 2 ）Checkerboard type, radial type, checkerboard ＋ ring, radial ＋ ring network are the often used forms of rail network; （3）The transfer function of the checkerboard type network is strong, so the layout of checkerboard ＋ ring rail network was considered only when the ring flow is developed;（4 ）The transfer points of the radial ＋ ring network tend to form a polygon, we need to pay attention to the location of the polygon, and notice to optimize the transfer line combination, in order to reduce the number of transfer and improve the ability of access to the road network ; （ 5 ） The research result can guide thelayout of urban rail transit network in practice, and can be applied in specific urban rail transit projects.
