铁路客运枢纽地区路网结构比较研究

路网结构是铁路客运枢纽地区规划设计中的重要因素。利用Google Earth软件获取国内外69个铁路客运枢纽地区的卫星图片,对其路网结构特征进行统计和分析。通过对比发现,国内外铁路客运枢纽地区路网结构的主要差异体现在路网密度、支路比例等方面。结合这些差异以及实地调查经验,指出我国铁路客运枢纽地区路网结构存在的问题：整体路网密度不高,路网级配不合理;新改建车站设计时过于重视进出站匝道的作用而忽视支路;铁路客运站集散交通汇入城市交通的关键节点设计不精细;疏散模式较为传统,周边轨道交通不发达。最后,对国内铁路客运枢纽地区路网设计提出了提高路网密度、增加支路比例、精心设计流线三点建议。

A Comparison of Road Network Layout Surrounding Rail Transit Terminals

The road network surrounding a railway transit terminal is an important element in the planning and design of a railway station.By capturing satellite images of 69 rail transit terminals inside and outside of China through Google Earth,this paper analyzes the characteristics of road network layout surrounding rail transit terminals.The comparison results show that there are differences between the domestic and overseasstations in roadway density and the proportion of feeder roads.Based on the analysis and f...
