摘　　要：匝道设计的合理与否,直接关系到高速公路的交通安全和运行效率。为改善高速公路出口匝道的安全现状,论文有针对性地阐述了出口匝道几何特征和控制方式的研究现状,并分析了国内外相关的标准规范;在此基础上指出现有研究存在的问题,例如,交通流导入方式不尽合理、匝道间距定义不够明确、匝道长度不足、连续的出口造成信息繁杂及衔接部的渠化控制不尽合理等;最后说明了依托项目所开展的相应的工作,为高速公路出口匝道交通安全和运行效率研究提供参考。Whether off-ramp design is reasonable or not is related to freeway traffic safety and efficiency. To promote safety status of freeway off-ramp, the paper expounded the research status at home and abroad on the ramp geometric characteristics and its control modes, and analyzed the main standards and criterions. Based on this, the corresponding problems existed in the present research were presented, for example： the way of traffic flow entering the off-ramp is not very reasonable; the definition of ramp spacing is blurred; ramp length is identification lack and the of study ： the successive off-ramp brings in more in canalization of the connective part is not very reasonable. formation Finally, some pertinent studies were pointed out, which provides reference to further promote the efficiency and safety of the traffic stream.
