城市轨道交通线路敷设方式统计分析——基于中国城市轨道交通协会数据分析的研究报告之六

Statistical Analysis of Urban Rail Transit Line Laying Mode——Report 6: Data Analysis of China Urban Rail Transit Association

线路敷设方式选择是城市轨道交通规划设计中的一个重要问题。基于2017年中国城市轨道交通协会数据,对2017年我国内地城市轨道交通线路敷设方式进行了统计;将线路分为4种类型,并分类统计分析了线路敷设方式随时间的变化趋势。通过对比分析我国内地郊区型城市轨道交通线路与日本东京和新加坡城市轨道交通线路的敷设方式、分布特征,发现我国内地城市轨道交通线路地上区间占比较低,近年来地下化趋势比较显著;提出合理选择线路敷设方式、提高线路地上区间占比等降低建设和运营成本的建议。

The selection of route laying mode is a crucial concern in urban rail transit planning and design.Based on the data from China Urban Rail Transit Association in 2017,the urban rail transit route laying modes of China inland cities in 2017 are summarized statistically,in which the routes are categorized into 4 types,and the transforming trend of route laying mode over time is classified for statistics.By comparing the route laying modes and distribution characteristics of suburban-type urban rail transit in China with similar ones in Tokyo and Singapore,the existing problems are pointed out,the proportion of ground section rail transit in China inland cities is relatively insufficient;while the underground rail transit construction trend is significant.Therefore,it is suggested that the construction and operation cost must be reduced by selecting rational route laying modes and raising the proportion of ground urban rail transit lines.
