摘 要：为了更全面的分析行人过街特性，为行人交通流的管理与控制提供理论依据，论文利用SPSS分析了不同性别行人过街速度特性，并采用Raff法计算不同速度的行人過街临界间隙。以长春市实际交叉口为例，对比分析了男性与女性过街的临界间隙值，结论表明，行人过街速度越大，能够接受的临界间隙越小。

The Critical Gap Characteristic based on the Across Street Velocity of Pedestrian

Abstract：To analyze pedestrian crossing characteristics more comprehensively and provide theoretical basis for pedestrian traffic flow management and control， this paper uses SPSS to analyze pedestrian crossing speed characteristics of different genders， and uses RAFF method to calculate pedestrian crossing critical gap of different speeds. Taking an actual intersection in Changchun as an example， this paper makes a comparative analysis of the critical gap between male and female crossings. The conclusion shows that the greater the pedestrian crossing speed is， the smaller the acceptable critical gap is.
