摘　　要：城市轨道交通速度目标值是指列车在线路正线上所能达到的最高运行速度,是项目前期确定设计标准、选择运营模式、匡算工程规模的重要依据。文章在分析速度目标值影响因素的基础上,提出城市轨道交通线路速度目标值的确定方法,即围绕上位规划和项目功能定位提出时空目标,结合多方式出行竞争性分析得到速度目标值范围,再根据站间距、线型条件、线路长度等,计算不同速度下的达速比、时空目标匹配性和节时效果,从供电、土建、车辆购置等方面分析不同速度目标下的工程投资差异情况,通过上述综合比选确定合理的速度目标值。然后,以某城市市域快线为例,采用上述方法确定其速度目标值,并验证速度目标值与运营模式选择的适应性和合理性,以期为后续城市轨道交通线路速度目标值的选择提供参考和借鉴。The target speed of urban rail transit is the maximum operating speed that a train can reach on main line.It is an important basis for determining design standards,selecting operating modes,and estimating the scale of the project in its early stage.On the basis of analyzing the factors affecting the target speed,this article proposes a method for determining the speed target for urban rail transit lines,which revolves around master planning and project function orientation to propose operation range and time-consuming goals.Combined with analysis of multi-mode travel competition,the range of target speed is obtained.Then,based on station spacing,route conditions,route length,etc.,the range of target speed reaching,operation range and time-consuming goals matching,and timesaving effect are calculated at different operating speeds.The differences in engineering investment under different target speed are analyzed from the aspects of power supply,civil engineering,and vehicle order,that the reasonable target speed is determined through comprehensive comparison above.Then,taking the urban express line of a certain city as an example,the above method is used to determine its target speed,and the adaptability and rationality of target speed and operation mode selection are verified,in order to provide guidance for the selection of target speed for subsequent urban rail lines.
