摘　　要：从道路使用者的角度对乘车舒适性与路面平整度之间的关系进行研究.以乘客的心电指标RMSSD(rootmean square of the squared differences of successive n-n intervals)为主要评价依据,选取平整度范围为1.06～5.53 m/km的12条沥青路面进行室外乘车试验.实验数据表明:不同速度下RMSSD随平整度的变化有明显的变化规律,同时结合主观打分法和振动加速度评价法,提出基于乘客舒适性的平整度临界值.The relationship between riding comfort and pavement roughness were studied from the view point of the road users in this research. RMSSD was selected to study passengers＇ riding comfort as a main evaluation index. In this study, 12 pavement sections with roughness changing from 1.06 to 5.53 m/km were selected to conduct on driving test in field. Test results show that, under different driving speed RMSSD changes obviously when the pavement roughness changes. In combination with the subjective scoring method and acceleration evaluation method, the critical value of roughness based on comfort considerations is proposed at different speeds.
