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

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 1 913 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 1 683 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 230 km，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。

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

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
