摘要
交通量、交通组成、轴载谱、轮胎接地压强、接地面积是研究重载交通行为特征的主要指标。实地调研、分析得出这些指标的代表值,并建立易于理解的交通流车型分类标准,可大大提高车型分类的便宜性和可操作性。
PCU, traffic structure, load spectra, load pressure and load equivalent area are the main indexes for the use of analyzing flow typical characters of heavy traffic. It can improve greatly the convenience and ma neuverability of vehicle type identification by analyzing the representative value of these indexes based on field survey and building understandable vehicle type identification standards.
