摘 要：為了更全面的分析行人過街特性，為行人交通流的管理與控制提供理論依據(jù)，論文利用SPSS分析了不同性別行人過街速度特性，并采用Raff法計(jì)算不同速度的行人過街臨界間隙。以長春市實(shí)際交叉口為例，對比分析了男性與女性過街的臨界間隙值，結(jié)論表明，行人過街速度越大，能夠接受的臨界間隙越小。

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.

Key words：signalized intersection， across street velocity， raff， critical gap
