摘要
针对京沪高速公路沂淮江段的交通量、轴载数据特征,对其进行路段划分,根据路段建立了交通量和当量轴载作用次数的预测模型,并分析了交通量增长率与当量轴次增长率的关系。研究结果可为京沪高速公路养护改造规划提供依据,也为类似工程提供参考。
According to the historical traffic volume and axle load data, Jinghu expressway Yihuai river section was divided into five sections. Then traffic volume and axle load forecasting model was received. At last the relations between traffic growth and the growth rate of equivalent axis times were studied, the results could porvide refferences to similar projects.
