摘　　要：提出一种新型波浪形减速路面的减速设施,具有舒适和行车顺畅的特点.利用室内驾驶模拟舱设计了四种波浪形减速路面,进行不同速度下的驾驶实验,测定反映乘车舒适性的车辆振动加速度,得到加速度和平整度、速度的回归关系,提出不同限速要求的波浪形路面设计方法和设计指标.研究结果表明,波浪形路面具有较好的减速效果,根据限速要求,通过铺筑不同的波浪形路面可以达到驾驶员主动减速的目的.It is suggested that a new kind of pavement to slow down the speed of the vehicle, which is called wave shape pavenaent and is benefit for riding comfort and for the passage of vehicle smoothly. In present study, four kinds of the wave shape pavement are designed and simulated driving test is performed by using driving simulation vehicle in the room under different driving speed. The mean square of weighed acceleration is recorded and the relation model among driving speed, mean square of weighed acceleration and wavelength of wave shape pavement is obtained, then the design method and index is induced accordingly. Test result shows that, the wave shape pavement can make driver to slow down the driving speed voluntarily, therefore the speed limit can be achieved by constructing suitable wave - shape pavement according to theory of this paper.
