摘　　要：对山区双车道旅游公路的交通特性进行了较为深入的定量分析。基于交通量的分析结果,从旅游旺季节假日前后旅游公路交通量增长的角度将旅游公路分为A、B、C3类。速度数据的分析结果表明:山区双车道旅游公路的现状车速偏高;陡坡路段速度离散性较大。这不仅与货车比例等交通组成有关,而且与陡坡路段自身的道路特性也有较大的相关性。The traffic characteristics of two-lane tourist highways in mountainous area have been analyzed quantitatively.Based on the analysis of traffic volume,the tourist highways are divided into A,B,C categories from the point of the growth of traffic volume before and after the holidays during the tourist season.The analysis of speed data shows that the speed on two-lane tourist highways in mountainous area is higher at present.The larger discreteness of speed on steep sections not only has great relevance with the large proportion of trucks,but also with the road characteristics of steep sections.
