摘　　要：结合交通量OD调查数据,对沈山高速及周边路网进行建模,分析模型产生偏差的原因并进行模型校正,最终得出可靠的路网模型,为沈山高速交通量预测提供基础,为改扩建技术标准的确定提供依据。Combined with OD survey data,this paper builds a model for Shenshan Expressway and its surrounding road network,analyzes the causes of model deviation and carries out model correction,and finally obtains a reliable road network model,which provides a basis for the prediction of traffic volume of Shenshan Expressway and the determination of technical standards for reconstruction and expansion.
