城市行人过街速度研究

为研究城市平面行人过街的速度及差别,分别对哈尔滨市冬夏两季的信号交叉口、无信号交叉口、环形交叉口、路段人行横道和自由过街5种不同过街条件下的行人过街速度进行调查。分析了冬季与夏季和不同过街条件下行人过街速度的变化以及形成原因;分析了行人年龄、性别、人行横道长度、过街行人数量和绿灯时间对行人过街速度的影响;采用数理统计方法,用15%位速度作为行人过街的设计速度,提出冬夏两季不同过街条件下的行人过街设计速度推荐值。

Research on Design Speed of Urban Pedestrian Crossing

In order to research on the difference between the speeds of pedestrian crossing line at grade crossing in urban area,the speed of the pedestrian crossing was investigated in the summer and winter of Harbin under five different conditions,signalized intersection,non-signalized intersection,rotary intersection,crosswalk,and free crossing;and the speed variation and its cause under different conditions in summer and winter was analyzed,including the effect of the age and the gender of pedestrians,the length of the crosswalk,the amount of the pedestrians crossing the street,and the green time;numeric statistic method was used,15th percentile speed used as the pedestrian crossing speed,and the appropriate values for crossing design speed under different conditions in the summer and winter was recommended.
