地铁通道内行人交通微观特性的实测分析

选取地铁车站的通道设施为主要研究对象,通过视频采集、后期人工处理得到行人流运动特征参数的一手数据资料。在借鉴国内外学者研究成果的基础上,采用SPSS软件对散点图进行分析,拟合出通道设施内行人流交通特征参数之间的理论关系曲线,回归得到相应数学模型。然后,结合行人流的运动特征,对通道内行人交通的微观运动特性作了进一步分析讨论。本文不仅完善了行人交通流理论研究,而且为行人设施设计和突发情况下的安全疏散提供了参考,保障轨道交通车站内客流乘行的迅速高效、安全有序。

Empirical Study of Pedestrian Microscopic Characteristics in Metro Station Corridors

Corridor facilities at a metro station were selected as the main object of this research, and the primary data of the pedestrian flow characteristic parameters were gotten by video-capturing and later artificial-processing. On the basis of present researches at home and abroad, the scatter diagrams were analyzed using SPSS software, and the theoretical curve relation of the pedestrian traffic characteristic parameters were fitted out, and the corresponding regression models were calculated. Then, combining with the pedestrian flow characteristics, the micro flow behavior in the corridor facilities was further analyzed and discussed. The research findings have some theoretical significance and practical application. Not only the relative pedestrian traffic theoretical research was improved, but also the pedestrian facility design and safe evacuation at emergency conditions were provided for reference. Therefore, passengers＇ rapid-efficient-safety-order travel at the stations has been guaranteed.
