基于客流预测成果控制地铁设计规模

How to Control the Design Scale of Metro Based on Passenger Flow Forecast Results

在城市轨道交通设计中,用好客流预测的结果对线路、车站、各系统的规模影响很大。通过西安地铁3号线规模设计实践,从全线路列车编组、线路两端车站、一般车站和换乘车站的规模设计等方面分析研究如何用好客流预测的成果,提出建议:设计时应注重敏感性分析结果在列车编组规模设计中的应用;对线路末端车站周边土地发展潜力要作充分估计;车站的规模设计要注重车站自身高峰小时客流;换乘车站的规模设计需综合考虑换乘客流的方向不均衡性及与进站客流的关系等因素。

In urban rail transit design, how to make use of the results of passenger flow forecast has a great influence on the scale of metro lines, stations and sub - systems ,etc. Based on the design practice of Xi＇an Metro No. 3, the author makes an analysis on how to use the passenger flow forecast results from the aspects of the design scale for train marshalling, terminal station, general station and transfer station. The author proposes that the designer should pay more attention to the sensitivity analysis when desig- ning train marshalling, fully estimate the development potential of surrounding land for terminal station, consider its peak hour pas- senger flow when designing general station and focus on the imbalance of transfer direction and the relationship with arrival passen- ger flow when designing transfer station.
