摘要
为优化人—机混合驾驶交通下的路面设计参数,归纳了不同驾驶模式下轮迹分布实测成果,建立了人—机混合交通流的轮迹分布模型,分析了不同自动驾驶占比对路面设计参数的影响。结果表明,自动驾驶货车轮迹分布标准差约为传统人工驾驶的1/3;对水泥路面设计参数影响较小,对沥青路面设计参数影响较大;沥青路面永久变形量随自动驾驶车辆占比增大而增大,最大增加约24%,路面寿命最高下降约36%,并提出了考虑自动驾驶车辆占比的永久变形计算公式。
To optimize pavement design parameters under human and machine mixed driving,distributions of the wheel track under different driving modes are summarized.A wheel track distribution model under human-machine mixed driving is established.Influences of automatic driving ratio on pavement design parameters are analyzed.The results show that the standard deviation of wheel track distribution for automatic driving is about 1/3 of manual driving,which have minor influence on the design parameters of cement pavement but great influences on asphalt pavement.The permanent deformation of asphalt pavement increases with the increase of the proportion of autonomous vehicles,the maximum increase is about 24%,the maximum road life is about 36%,and the calculation formula of permanent deformation considering the proportion of autonomous vehicles is proposed.
