高速公路匝道路段变速车道隐患排查

高速公路互通枢纽匝道的变速车道(加减速车道)路段是交通违法和交通事故多发的点段,特别是交通流量密集路段,交通事故风险更为明显。本文结合高速公路变速车道的交通设计规范,就车道的设计长度进行实际测量探析,通过介绍相关国标规范设计要求,举例对照变速车道设计存在缺陷的道路安全隐患,分析提出隐患改善的相关治理建议。

The road section of variable speed lane(acceleration and deceleration lane)on the ramp of the expressway interchange hub is the location where traffic violations and traffic accidents occur frequently,especially in the section with dense traffic flow,the risk of traffic accidents is more obvious.Based on the specifications of traffic design for the variable speed lane of expressway,this paper analyzes the actual measurements of the design length of the lane,and through the introduction of the design requirements of relevant international standards and specifications as well as examples of road safety hazards on the variable speed lanes with defects in design,puts forward relevant treatment recommendations for the improvement of the hazards.
