| 摘 要： | 路面平整度和行车速度单独或联合作用都会对行车舒适安全性产生重要影响。通过设计正弦波路面,开发室内模拟舱正弦波路面场景,开展室内驾驶模拟实验,研究了路面平整度对驾驶员选择驾驶速度的影响,拟合出了国际平整度指数IRI与车速间的关系曲线,并对比了世界银行技术文件推荐的IRI数值下的速度值。研究表明,文中得出的不同平整度下的舒适驾驶速度与世界银行推荐值基本吻合,不同平整度时驾驶员会以不同的驾驶速度进行驾驶,波浪路面具有较好的限速效果。

| Abstract: | IRI and driving speed and their combination has important influence on the driving comfortable and safety.The pavement with sine wave shape were designed in the indoor simulation chamber,and driving simulation experiment was carried out for studying the influence of pavement roughness on the drivers choosing driving speed.After analyzing,the relation curve was finally obtained,being compared with the estimation scale proposed by the World Bank,and the results were consistent essentially.Test result also sho... |
