摘　　要：首先描述了步行通道行人走行延误的研究现状,接着从通道空间结构布局与行人流特点两个方面分析了步行通道走行延误的影响因素。将通道中的延误分为路段延误与节点延误,并分别建立了计算模型,路段延误模型基于经典的BPR函数,节点延误模型采用了修正的韦伯斯特延误模型,最后应用算例对模型进行了验证,得出行人流量在接近饱和流的状态下,路段的延误时间明显。The paper first summarizes the current situation of researches on the delay of pedestrian travels on walkways and then analyzes the factor influencing the delay from the aspects of passage spatial layout and pedestrian flow. It divides the delay into delays along the lane and detainment at the node and sets up computational models for both of them, the one for delays along the lane based on the classic BPR function and the one for detainment at the node a modified Webster delay model. Finally the models are tested using a numerical model and the result shows that when the passenger flow nears saturation, the delay tends to be more obvious.
