为衡量城市轨道交通线路的旅行速度所发挥的效率，引入速度效率的概念。基于我国170条城市轨道交通线路的运营数据，涵盖全封闭运行的地铁、轻轨、单轨系统等，只考虑站站停的列车运行模式，从平均站间距和线路设计速度两个方面对旅行速度和速度效率进行分析，结果表明：大部分线路（约64%）设计速度为80km/h，平均站间距在1.0~2.5km之间，其中89.9%的线路旅行速度分布在30~40km/h，速度效率分布在37.5~50.0%。此外，量化分析了旅行速度和平均站间距、设计速度正相关的变化关系以及速度效率与平均站间距正相关、与设计速度负相关的变化关系。最后，基于实际数据拟合的旅行速度和速度效率公式，计算得到了平均站间距、设计速度、旅行速度和速度效率的对应分布关系，可为衡量城市轨道交通线路旅行速度和速度效率的合理范围提供参考。

In order to measure the efficiency of travel speed of urban rail transit lines, the concept of speed efficiency is introduced. Based on the operating data of 170 urban rail transit lines in my country, it covers the fully closed-operated subway, light rail, monorail system, etc., only considering the train operating mode of the station parking, from the average station spacing and line design speed to travel speed and travel speed and travel speed and travel speed and travel speed and travel speed and travel speed and travel speed and speed of travel. The speed efficiency is analyzed, and the results show that most lines (about 64%) design speed is 80km/h, and the average station spacing is between 1.0~2.5km, of which 89.9% of the line travel speed is distributed at 30~40km/h, the speed is The efficiency is distributed at 37.5~50.0%. In addition, quantitative analysis of changes in travel speed and average station spacing, design speed correlation, and changes that are correlated with the average station spacing positive and negatively related to the design speed. Finally, based on the fitted travel speed and speed efficiency formulas based on actual data, the corresponding distribution relationships of average station spacing, design speed, travel speed and speed efficiency were calculated, which can provide reference for measuring the reasonable range of travel speed and speed efficiency of urban rail transit lines.
