为了加强多车道高速公路的运行管理,对车道限制策略进行研究。介绍了车道限制策略的概念、目的和意义。以车道性质和车型分类为基础,以车辆混行的事故特征为依据,提出车道限制策略的构建原则和思路,并为6～10车道高速公路分别制定推荐方案。以宁沪高速公路为例,分析了实施车道限制策略前后的交通事故数据,证明其对于改善多车道高速公路交通安全有明显效果。最后,针对存在的问题提出相应建议。
In order to strengthen the operation and management of multi-lane expressway, the lane restriction strategy is studied. The concept, purpose and significance of lane restriction strategy are introduced. Based on the nature of the lane and the classification of the vehicle type, the principle and idea of lane restriction strategy construction are put forward based on the accident characteristics of the mixed traffic lane. The recommended schemes for 6 ~ 10 lane expressways are respectively formulated. Taking the Ninghu Expressway as an example, the traffic accident data before and after the implementation of the lane restriction strategy are analyzed to prove that it has obvious effect on improving the traffic safety of the multi-lane expressway. Finally, we put forward corresponding suggestions on the existing problems.
