市域快速轨道交通合理站间距研究

市域快速轨道交通的功能定位是中心城和新城以及新城之间的快速联系,主要服务于通勤客流,因此在前期研究过程中,全线设站在满足沿线的客流需求之外,还应满足主要区域之间的通达时间要求。在具体确定设站间距时,首先应结合市域快速轨道交通车站直接吸引范围内的规划人口和岗位数量,并参考预测客流量,同时考虑与其他轨道交通换乘,明确各个车站的设置必要性,之后按照较高的设计速度计算重点区域间的旅行时间。若结果无法达到时间目标要求,可以经过经济技术比选后,在有条件的车站设置配线,通过灵活的运营组织满足快速通达要求,否则就需要考虑减少设站。

Study on Rational Distance between Stations of Rapid Rail Transit

Rapid rail transit, which falls between railway and urban rail transit in a multi-level rail transit system, is being increasingly implemented in China. Its objective is to provide fast connections between a central city and newly developed towns, especially for commuters. Therefore, the transit system should meet both the target travel time expectations between the main sections and passenger requirements. Locations of stations should be set by population and employment predictions. To this end, the passenger flow forecast and operations of existing rail stations are used as references. Then, according to the current station scheme, we calculate the travel times between the main areas based on the highest design speed. If the outcome does not meet targeted commute times, some stations could add arrival and departure tracks after economic and technical analyses to allow express trains. If an analysis indicates that the target time cannot be met by the express trains, the number of stations must be reduced.
