摘　　要：采用德尔菲法分别从路面铺装情况、公路技术等级和公路使用年份三种因素影响情况下对道路行驶质量进行打分,并采用模糊聚类和层次划分的方法对路面平整度进行划分,建立道路铺装类型、技术等级及使用年份与路面平整度之间的对应关系。进而按照道路的平整度分布情况对道路样本进行聚类划分,运用均匀分布随机抽样函数对各个聚类进行随机抽样,最终完成典型道路路段的选取。运用以上方法选取镇江地区的部分典型路段进行平顺性试验,试验数据分析结果表明德尔菲法获得的分值与真实的道路行驶质量指数有很好的一致性,验证了典型路段选取方法的可行性。The quality of driving on roads from the material of road, highway technical level and highway use year are marked using the Delphi method in this paper. Then surface evenness are classified using Fuzzy Cluster Analysis and level division method, and the corresponding relationships between the pavement types, technical grade, use year and surface evenness are established. Combined with the distribution situation of surface evenness, the qualitative methods and principles with the quantitative division are blended to select the same sample, the principles are integrated, Unidrnd（N,m,n） function is used to choose the typical section of road. The typical section of road in Zhenjiang region which are used for ride comfort experiment is selected by using these methods. The results of the experiment show that the figure of the Delphi method is similar with real riding quality index of the road. So the methods of selecting typical road are proved availably.
