摘要
针对传统数据采集和研究模式中的不足,论文提出了基于车辆轴型分类的车辆轴载谱来分析高等级公路车流轴载、公路货运车辆运营成本和超限严格管制下公路货运运力结构预测的新方法,其基本思路为按轴型和车辆载重状态划分车型、开展轴载和交通量调查、计算不同车型的轴载谱、对各车型各轴型的轴载谱进行Gauss曲线拟合、再根据拟合函数进行车辆轴载、运营成本和运力结构的计算,文中还结合世行安徽公路项目II(超载运输课题研究)进行了实际应用。
Given the fact of the shortage of data collected and research methods in the related research of highway truck fleet configuration, the new way to analyze conversion model of axle load of high-grade highway transportation, highway vehicle operating cost, prediction of highway truck fleet configuration under over-limit prohibition based on table of axle load is put forward. The basic study process includes vehicle classification based on axle type and loading state, axle load and traffic flow survey, different vehicles＇ axle load distribution chart, different vehicles＇ axle load distribution chart matched curve fitting, finally, the vehicle axle load, highway vehicle operating cost and highway truck fleet configuration calculated based on the fitted functions. These new methods are used and tested in the analysis of the overloading contro in Anhui province.
