市域轨道交通快线合理站间距分析

Analysis on Reasonable Station Spacing of Urban Rail Transit

市域轨道交通快线能够为旅客提供中长距离的快速位移,主要功能是加强城市中心区与新城或新城与新城之间的联系。车站间距的合理与否直接影响到轨道交通效益的发挥,并对城市空间结构、沿线土地开发等有深远的影响,站间距过小或过大都可能会产生不利的影响。本文通过分析列车巡航速度和乘客出行时间等综合影响因素,结合多个参数,对站间距进行了建模求解,并结合成都市城市快速轨道交通9号线的实际情况计算合理站间距。

Regional rail transit provides passengers rapid transportation in long distance.The main function of regional rail transit is to strengthen links between the suburb with the downtown or between suburbs.Reasonable station spacing directly affects the profit of rail transport,and has profound impacts on urban spatial structure and land development along the rail.Also,it would have a negative impact if the station spacing is too small or too large.This article analyzes various factors such as design speed and passenger travel time,and solves the model under different parameters Chengdu Urban Rail Transit Line 9 is used to prove the method.
