【摘要】：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。
[Abstract]:Research purposes: in recent years, large and medium-sized cities continue to vigorously promote the construction of urban rail transit, and network planning is an important basis for guiding the short-term construction and long-term development of urban rail transit. Urban road is the carrier of urban rail transit, and the passenger flow along the line is the basis of the future co-directional rail line. In order to fully understand the relationship between urban road network form and rail transit network form, and to provide reference for urban rail transit network planning, this paper combs the two forms, analyzes the relationship between them, and focuses on the chessboard road network. Theoretical exploration is made on the key points of the layout of rail transit network in the radial ring network city. The conclusions are as follows: (1) there are some similarities between urban rail transit network and urban road network, (2) Checkerboard type, radiative type, chessboard ring and radial ring network are often used in rail network. (3) the transfer function of the chessboard type network is stronger, so only when the annular passenger flow is developed, the layout of the chessboard type circular rail network should be considered; (4) the transfer points of radial ring network often form polygons, so we should pay attention to the rationality of polygon position and optimize the combination of transfer lines in order to reduce the times of transfer and improve the access ability of the network. (5) the results of this study can guide the layout of urban rail transit network in practice, and can be used in the practical application of specific urban rail transit projects.
