摘要
信号交叉口行人步行速度是交通信号设置和安全分析的一个重要指标,根据采集到的西安市高新区典型十字信号交叉口行人步行速度数据,通过SPSS软件运用数理统计方法对数据进行分布拟合、统计性描述,探讨了行人自身特性和交叉口特性影响下行人过街速度特征.研究表明,男性和女性步行速度分布都符合正态分布,青年、中年和老年行人速度分布符合对数正态分布;同一个路口相交道路等级相差较大时,通过不同人行横道的行人平均步行速度值相差较大;最后,给出了设计步行速度推荐值.
Pedestrian walking speed when crossing signalized intersection is an important parameter in traffic signal design and traffic safety analysis.Data acquisition of pedestrians walking velocity at typical signalized intersection in Xi'an high-tech Industrial Development zone and data-analysising used mathematical statistical methods for distribution fitting and statistic description by the SPSS software,the paper discusses the speed characteristics under the influence of pedestrian characteristics and the intersection geometrical features.Studies have shown that men and women walking speed distribution are in line with the normal distribution,and that youth,middle-aged and elderly pedestrian speed distribution comply with the log-normal distribution;The length difference degree of pedestrian crossing affects pedestrian speed at a signalized intersection.Finally,the paper puts forward the recommended value of pedestrian crossing design speed.Reference and basis are provided for pedestrian signal lights timing setting,pedestrian crossing geometric design,traffic safety analysis and so on.
