摘　　要：分析交叉口事故多发原因时发现,除机动车之间的交通冲突外,机动车和行人之间的交通冲突也是造成事故的一大原因。道路调查发现,在无信号交叉口,行人会根据当前路段的道路情况,在适当时机,以一定速度通过;在信号交叉口,尽管有信号灯指引以规避可能的交通冲突,但是由于行人的从众,争抢等问题,产生诸多交通安全隐患。文章分析行人在信号交叉口过街时的时机和步速的关系发现,行人整体过街时的步速比在道路两侧行走更快,不遵守信号灯的行人步速比遵守信号灯的行人步速快,以及在相同过街条件下,零零散散过街的行人比成群结队过街的行人步速快。Through analyzing the reasons of accidents happened in the intersections,The traffic conflict between pedestrians and motor vehicles is a major cause of the accidents,besides the traffic conflict between motor vehicles.The road survey found,firstly,pedestrians prefer to pass the no-signal cross at a regular speed in the appropriate road condition and time.Secondly,at the signal intersection,even though the traffic lights could help pedestrians avoid most of traffic conflicts,due to crowd mentality of pedestrians or being in hurry,they may not obey the traffic rules and follow other people.Therefore,there are still many potential traffic risks.The paragraph analyzed the timing and paces of pedestrians passing the intersection at the signal crossroad,drew a conclusion that pedestrians usually walk faster across the intersections than people walking on sides of the road within one-way ANONA.Moreover,pedestrians disobeying the traffic lights usually have faster paces compared with those who obey the rules.In the same traffic condition,single pedestrian usually go through the cross faster than a large crowd.
