摘要
针对目前路面设计方法中对于横向分布系数认识的不足 ,通过对高速公路行驶车辆的实地观测 ,得到了典型高速公路上各种车型的实际横向分布系数值和车辆横向分布特征。并根据统计分析提出 ,采用白天中等交通量时段作为实地调查时段 。
In view of the inadequacy in the current pavement design methods, the traverse distribution characteristics and coefficients of all types of vehicles on typical freeways were obtained and determined from field surveys. Statistic analyses of the survey results indicate that surveys at daytime with medium traffic volume can better represent the overall transverse distributions of the day than other hours.
