高速公路改扩建施工区限速研究

Research on Speed Limit in Reconstruction and Expansion Construction Area of Expressway

在对公路限速值与通行能力、交通安全理论分析及相关问卷调查的基础上,确定高速公路改扩建施工区合理的限速值,并以佛开高速改扩建工程为实例提出三种施工区限速方案进行仿真分析,提出高速公路施工区的限速方案。

On the basis of speed limit values and traffic capacity of highway, theoretical analysis of traffic safety and relevant questionnaire survey, the reasonable speed limit values in the reconstruction and expansion construction area of expressway are determined, simulation analysis on three kinds of speed limit schemes in the construction area proposed by the example of reconstruction and expansion project of Foukai Expressway is made, and speed limit schemes in the construction area of expressway are put forward.
