中文摘要：

通过对行人穿越人行横道进行调查,并用spss统计软件的二元logistic线性回归方法对调查数据挖掘,得出行人穿越人行横道概率模型,进而计算出了临界间隙.对比分析个体与群体过街概率模型和临界间隙模型,发现在不同车头时距下,个体与群体过街的概率存在差异,且群体过街的临界间隙小于个体过街的临界间隙.

英文摘要：

The paper establishes probability model of individual and group across the street by spss bi- nary logistic regression mining the data of the investigation on the pedestrian crossing, then gets the critical gap model by probability model. The result indicates that individual and group probability mod- el are different under the different headway. Also the critical gaps of group across the street is less than the individual.
