城市轨道交通旅行速度影响因素分析及提升实践

从不同地铁运营线路之间的旅行速度存在差异入手,分析影响旅行速度的主要因素及程度,包括平均站间距及最高运行速度、区间限速、列车运行等级、开关门效率、乘客乘降时间等,其中拟合了最高运行速度为80 km/h的运营线路旅行速度与平均站间距之间的函数关系,为评价各线旅行速度的实际表现提供工具。最后结合运营线路旅行速度提升需求,从区间限速、列车运行等级、开关门效率、乘客乘降时间4个方面提出了对策思路,并给出了上海地铁的应用案例。

Influencing Factors and Improvement Practice of Traveling Speed of Urban Rail Transit

Beginning from the difference in traveling speeds between different metro lines, this study analyzed the main influencing factors and degree of traveling speed, including the average station spacing and maximum operation speed, speed limit, train running level, efficiency of door opening and closing, and frequency of passenger riding and landing. The functional relationship was fitted between the traveling speed and average station spacing in operation lines with a maximum operation speed of 80 km/h, which can facilitate evaluation of the actual traveling speed. Finally, along with expressing the demand for improving the traveling speed of the operation lines, the paper puts forward countermeasures from the last four influencing factors and provides an application practice for the Shanghai Metro.
