城市轨道交通线路区间设计速度的发挥程度是运输组织优劣和运营经济性的基础.在列车区间运行速度的基础上引入速度效率的概念,用以衡量区间运行速度发挥的效率.从线路站间距、区间设计速度、列车性能3个方面分析对区间运行速度和速度效率的影响,得到结论:站间距与区间设计速度存在最优匹配,当站间距分别为小于1.3 km,1.3~1.5 km,1.5~3.9 km,3.9~6.6 km,大于6.6 km时,区间设计速度分别选择80 km/h,100 km/h,120 km/h,140 km/h,160 km/h较为合适.并且,在站间距低于4 km时,列车区间运行速度随区间设计速度的增大,呈现出先增后降的变化特点,而速度效率与区间设计速度呈负相关变化,且变化率逐渐减小.最后,基于速度效率的理论计算公式得到不同区间设计速度和站间距对应的区间运行速度和速度效率的取值范围,可为未来轨道交通线路的建设运营及技术标准的修订提供参考.
Speed Efficiency of Urban Rail Transit Lines
he performance of the interval design speed of urban rail transit lines is the basis for the efficiency of transportation organization and operational economics.The concept of speed efficiency was introduced based on the train's interval running speed,so as to measure the efficiency of the interval running speed.By analyzing the impacts of factors such as station spacing,interval design speed,and train performance on the interval running speed and speed efficiency,this paper drew the following conclusion:There is an optimal match between station spacing and interval design speed.Specifically,when the station spacing is less than 1.3 km,1.3~1.5 km,1.5~3.9 km,3.9~6.6 km,and more than 6.6 km,the recommended interval design speeds are 80 km/h,100 km/h,120 km/h,140 km/h,and 160 km/h,respectively.Moreover,when the station spacing is less than 4 km,the train's interval running speed increases and then decreases as the interval design speed increases,while the speed efficiency is negatively correlated with the interval design speed,and the rate of change gradually decreases.Finally,based on the theoretical calculation formula for speed efficiency,the range of interval running speed and speed efficiency corresponding to different interval design speeds and station spacing is obtained,which can be used as a reference for the construction and operation of rail transit lines and the revision of technical standards in the future.
