摘　　要：高速公路出口匝道与地面道路衔接部是高速公路与地面道路交通流转换的枢纽,交通流溢出现象时有发生,是交通事故的频发区域之一,研究其交通安全改善的方法,对提高高速公路交通安全状况和整体效益的发挥具有重要的意义。本文在分析国内外出口匝道与地面道路衔接部研究的基础上,提出了衔接部的交通安全改善方法,从影响范围的界定、交通安全诊断、交通安全问题分析、交通安全改善、交通安全改善方案评价及制定等方面进行了探讨,并以此为基础,以山西省汾军高速公路出口匝道与340省道衔接部为例,进行了衔接部交通安全改善实例分析。研究表明本文提出的衔接部交通安全改善方法是一种简单、可操作性强、快速的交通安全改善方法,对我国现阶段衔接部的交通安全改善具有一定的指导意义。A ramp-street junction is a transfer station for the traffic flow between freeway and street,which always causes traffic backup.Appropriate traffic safety improvement method for the ramp-street junction is significant for the improvement of freeway performance and its capacity.Based on the latest researches,a recommended traffic safety improvement framework was established which included the junction influencing area,traffic safety diagnosis,safety problem analysis,traffic safety improvement counter-measures,traffic safety improvement evaluation and the determination of safety improvement plan.The framework was applied to the planning project of a ramp-street junction between Fen-jun freeway and 340 provincial highway in Shanxi province.The example proved that the presented method was practicable and applicable in the safety improvement of the ramp-street junction.
