【摘要】 公路平面交叉口是交通事故的集中发生地,改善公路平面交叉口交通安全是降低我国交通事故数量的重要途径。通过对江苏省部分国省道公路平面交叉口进行实地交通调查,从交叉口基础设施建设的情况出发,对引起公路平面交叉口交通事故的因素,包括交叉口位置,几何属性情况,交通标志标线,信号设置和交叉口交通环境等方面进行了简要的阐述。根据这些方面存在的交通安全问题提出公路平面交叉口交通安全的主要改善措施,并以实例进行分析说明,为改善公路平面交叉口交通安全提供具体的方向和依据。更多还原

【Abstract】 Highway intersections are the main positions where traffic accidents occur, so one important approach for decreasing the quantity of traffic accidents is to improve traffic safety at highway intersections. By surveying some highway intersections in Jiangsu province, factor analysis of traffic safety at intersections has been concretely made. These factors include intersection positions, geometrical attributes, traffic signs and markings, traffic signals and traffic conditions. Then, the relevant advisories were provided. Finally, anexample was given for indicating the application.更多还原
