中文摘要：

降低危险路段车辆行驶速度，是减少山区高速公路交通事故的有效手段。分析了高速公路常用减速设施存在的不足，提出了一种新型的振动减速路面。阐述了振动减速路面的设计原则和设计方案，运用TruckSim仿真软件对振动减速路面的设计方案进行了测试和比选。在此基础上，以云南罗富高速公路为对象，对振动减速路面进行了工程应用。结果表明，试验路段振动减速路面出口处平均车速比入口处降低了40．1％，同时85％位车速和最大车速也明显下降，有助于提高山区高速公路交通安全水平。

英文摘要：

Reducing vehicle speed on dangerous sections is an effective means to decrease traffic accidents on expressways in mountainous area. The shortcomings of common speed control facilities are analyzed in this article, and a novel speed control pavement is proposed. The principle and design scheme of speed control pavement are described, then simulation testing and comparison are completed using TruckSim software. The speed control pavement is applied on Yunnan Luo-Fu expressway, and actual results show that the speed control pavement can reduce the average speed by 40. 1%, while the 85th percentile speed and the highest speed are also decreased significantly, which is helpful to improve traffic safety of expressway in mountainous area.
