摘　　要：为了分析我国城乡结合部的行人过街安全情况,使用交通冲突和行人安全性指标对城乡结合部行人过街进行了探索。对行人和机动车冲突的特点进行了分析,并介绍了行人和机动车冲突的形成过程。通过现场调查视频和人工提取,获取相关参数,计算得到了行人和机动车冲突的距碰撞发生的时间和后侵占时间指标,并使用行人安全性指标对行人过街的安全性展开了分析,结果表明,所调查的地点均处于不安全的状况,设施设置越齐全,车流量越少,行人的安全性越高。In order to analyze the pedestrian safety at rural-urban fringe, the pedestrian crossing characteristics are explored using the traffic conflict technology. Firstly, the features and the forming processing of the conflict between the pedestrian and vehicle at the rural-urban fringe are described. The data is collected through the field video and manual detection methods, and the time-to-collisions （TTC） and post-encroachment-time （PET） are calculated using the collected data. The pedestrian risk index（PRI） is used to evaluate the pedestrian＇s safety. It is proved that the data collection site is in danger degree, moreover, the more complete of the traffic facilities and the less traffic flow, the more safe of the pedestrian. The results can provide reference for the safety facility setting at the rural-urban fringe.
