中国内地城市轨道交通全自动运行线路运营与建设统计分析

Statistics and Analysis of Operation and Construction of Fully Automatic Urban Rail Transit Lines in China

统计国内城市轨道交通全自动运行线路的建设和运营情况,介绍全自动运行线路及线路规模、全自动运行等级、开通时间,分析近年来国内全自动运行线路建设和运营里程增长趋势、各城市全自动运行线路的建设规模、全自动运行等级情况,以及信号和列车供货商情况。数据表明,截至2021年底,国内共计有24个城市建设全自动运行线路65条,建设总里程1913 km,其中有15个城市已开通全自动运行线路,数量为29条,运营总里程932 km。采用自动化等级GoA4的线路共58条,占总线路数量的89.2%,里程1683 km,占总里程的87.9%;采用GoA3的线路共7条,占总线路数量的10.8%,里程230km,占总里程的12.1%。统计结果表明,GoA4自动化等级已成为全自动运行线路的优先选择。国内全自动运行线路已有选用的全自动运行信号供货商11家,列车供货商10家,且多为国内供货商,表明已实现自主知识产权,这有利于我国轨道交通技术装备的创新,从而推动交通强国目标的实现。

This study leverages statistical data to examine the construction and operation of domestic urban rail transit lines in China that have integrated fully automatic operation(FAO)technology.It provides an overview of these automated lines,including their scale,the grade of automation used,and the commencement times of operations.The paper also presents an analysis of recent growth trends in the construction and operation mileage,the quantity and mileage of automatic lines in each city,and the application of different grades of automation(GoA).By the end of 2021,data reveals that 24 Chinese cities have constructed 65 fully automatic lines,spanning a total distance of 1,913 kilometers.Out of these,15 cities have 29 fully operational automatic lines,covering a total length of 932 kilometers.Among the automated lines,58 utilize GoA4,representing 89.2%of all automatic lines and covering 1,683 kilometers or 87.9%of the total distance.Conversely,7 lines utilize GoA3,accounting for 10.8%of all automatic lines and spanning 230 kilometers or 12.1%of the total distance.GoA4 has emerged as the most popular choice for fully automatic lines.The paper also examines the usage of signaling system suppliers and train suppliers on these automatic lines.Notably,there are 11 signal suppliers and 10 train suppliers deployed across domestic automatic lines,with the majority being domestic providers.These suppliers have achieved independent intellectual property rights,fostering 2 URBAN RAPID RAIL TRANSIT innovation in rail transit technology and equipment.
