摘　　要：慢行交通混合过街时相互干扰较多,过街特性与一般的行人或电动自行车过街有所不同。本文对福州地区5个信号交叉口的慢行交通过街交通流和交通冲突进行调查,并使用SPSS软件对实测数据进行了统计分析,从而描述慢行交通混合过街交通流特性并建立交通冲突模型。研究得到电动自行车过街平均速度的均值是7.89km/h,行人过街平均速度为4.37km/h;随着慢行交通密度的提高,慢行交通速度呈现下降的趋势。最后将冲突模型预测值与实测值作比较,检验了冲突回归模型的有效性。There are a lot of interferences when mixed slow traffic across the street.Characteristics of a pedestrian and bike across the street is different.In this paper,we investigate mixed slow traffic flow and traffic conflicts in the crosswalk at 5 signalized intersections of the Fuzhou region.We use SPSS software to analyze the measured data and describe the mixed slow traffic flow characteristics and establish the traffic conflict models.The average speed of electric bicycle in the crosswalk is 7.89km/h and the average speed of pedestrian is 4.37km/h;with slow traffic density increases,the speed of slow traffic showed a downward trend.Finally,we compare the conflict model predictions and measured values and test the effectiveness of conflict regression model.
