摘　　要：受生理、心理及交通安全知识等因素的影响,学龄儿童在信号交叉口处的过街安全尤为特殊.为深入了解学龄儿童过街行为特性,以小学附近的信号交叉口为研究区域,采用实地视频调查法,采集了下学期间大量带有父母-学龄儿童结伴过街行为的视频,利用SIMI Motion软件处理采集得到的视频数据提取得到了过街行为的相关参数,包括行走轨迹、过街速度、过街时间等;进一步,结合人工标定方法,划分了结伴过街和独行过街等不同过街类型,并利用SPSS软件对不同过街类型的过街行为参数的差异特性进行了差异显著性分析,量化了不同过街类型之间的异同特征.研究结果不仅对理解带有父母-学龄儿童结伴过街这类复杂行人交通流的交通动力学特性具有重要意义,而且可为学校周边交叉路口的基础设施建设提供了前期的依据.Influenced by factors such as physiology,psychology,and traffic safety knowledge,the safety of school-age children crossing streets at signalized intersections is particularly unique.Therefore,it is of utmost importance to deeply understand the characteristics of street-crossing behavior among school-age children.Using a signalized intersection near a primary school as the research area,a field video survey method was employed to collect a large number of video footage featuring parents and school-age children crossing the street together during the end of school hours.The SIMI Motion software was used to process the collected video data and extract related parameters of street-crossing behavior,including walking trajectory,crossing speed,and crossing time.Furthermore,different crossing types,such as companion crossing and solo crossing,were distinguished using manual calibration methods.SPSS software was utilized to analyze the varying characteristics of crossing behavior parameters for different crossing types,conducting a significant difference analysis to quantify the similarities and differences among them.The research results are not only of great significance for understanding the traffic dynamics characteristics of complex pedestrian traffic flows involving parents and school children crossing the street together but also provide a preliminary basis for infrastructure construction around school intersections.
