摘要
高速公路的限速受法律、道路、交通等因素的影响。以大循高速公路为例,在分析道路设计指标适用性的基础上,综合其他相关因素,确定其最高限速值为80km/h,进而研究制定了大循高速公路的限速方案。针对长大下坡路段易出现超速的问题,研究设置相关交通安全设施,配套交通管理、交通服务措施,确保车辆不超速行驶。
The speed limit of expressway is influenced by law,road,traffic and other factors.Based on the analysis of the applicability of road design indicators and other relevant factors,the maximum speed limit value of Daxun Expressway is determined to be 80 km/h,and then the speed limit scheme of Daxun Expressway is studied and formulated.Aiming at the problem of overspeed in long downhill section,this paper studies the establishment of relevant traffic safety facilities,supporting traffic management and traffic service measures to ensure that the vehicles do not overspeed.
