路肩隆声带应用安全性试验研究

路肩隆声带是警示驾驶人提高注意力,减少单方事故的一种有效的道路安全设施。为了评价路肩隆声带对车辆的安全性影响,提出了采用车辆前轴振动加速度值、方向盘振动角加速度值作为车辆冲击状况和方向稳定性的评价参数。在3种车型、5种型式隆声带道路试验的基础上,建立了定量描述路肩隆声带主要结构尺寸与安全性能评价参数之间的经验模型,为路肩隆声带的应用安全效果分析提供了工程计算方法。

Test and Study on Application Safety of Shoulder Rumble Strips

Shoulder rumble strips are a kind of effective road safety facilities,which warn drivers to raise attention and decrease single vehicle accidents.In order to evaluate the application safety of shoulder rumble strips,the values of vibration acceleration at the front axle and angular acceleration of steering wheel are adopted as the evaluation parameters of impact condition and directional stability of vehicle.On the basis of road tests of three vehicle types and five different types of shoulder rumble strips,the model on the dimensions of rumble strips and application safety is built,which presents the engineering computation method for analyzing the safety effect of shoulder rumble strips.
