对南宁~友谊关高速公路进行广泛的调研,以大量数据资料为基础,分析路段运行车速特征、道路使用者的交通需求、道路几何设计特点、道路安全状况等方面的具体问题,探求运输效率与安全之间的合理平衡点,给出了以工程研究限速方法为基础,以全线限速和局部限速为具体实施策略的分路段运行速度管理与控制方案。
Extensive research on Nanning ~ Youyiguan Expressway is conducted based on a large amount of data and data. Based on the analysis of the speed characteristics of road sections, the traffic demand of road users, the geometric design features of roads, the road safety status and other issues, Safety and a reasonable balance between points, given the method of engineering research based on the speed limit, and the full speed limit and local speed limit for the specific implementation strategy of sub-section speed management and control programs.
