地铁车站同时在站人数模型研究

Study of the Simultaneous Station Occupant Model

为了更准确地计算地铁公共区的人员空调负荷,需要确定车站的同时在站人数。本文提出地铁车站同时在站人数计算模型及旅客停留时间参数的辨识方法。该模型采用实时统计的客流量和进站,出站旅客停留时间可以计算地铁车站同时在站人数。本文以武汉某地铁车站作为研究对象,进行了同时在站人数的测量和进站,出站旅客停留时间的参数辨识,并对结果进行实验验证。模型验证结果表明,该模型计算的同时在站人数与实际测量同时在站人数基本一致,最大相对误差为5.6%。结果表明该模型具有很好的准确性与可靠性。该模型可为地铁车站空调负荷预测及控制提供参考。

Simultaneous station occupants are usually required for accurate cooling load calculation for the pubic area of subway stations.This paper presents a simple simultaneous station occupant number model and the identification of stranded time of passengers.This model can calculate the simultaneous station occupant number by using the incoming passenger flow,exiting passenger flow,the stranded time of the incoming passenger,and the stranded time of the exiting passenger.This simultaneous station occupant number model is validated by the experimental test in a subway station in Wuhan.The results show that the simultaneous station occupant number calculated by the model has a good match with the experimental value.The relative error is about 5.6%showing good accuracy and reliability.This model can be used as reference for cooling load prediction and control of subway stations.
