摘　　要：改扩建对协调高速公路结构、交通需求和提升高速公路的通行能力具有重要意义。文章主要收集了某高速公路交通数据信息,预测未来几年高速公路交通流量,根据预测结果优化公路平面、高速公路设计速度,通过分析公路边坡稳定性,优化高速公路改扩建纵面。公路交通测试结果表明,高速公路拥堵时间在规定范围内具有良好的改扩建效果。Reconstruction and expansionis of great significance for coordinating expressway structure,traffic demand and improving its passing capacity.This paper mainly collects the traffic data information of an expressway,predicts its traffic flow in the next few years,optimizes its plane and design speed according to the prediction results,and optimizes its reconstruction and expansion longitudinal surface by analyzing the slope stability.The expressway traffic test results show that the expressway congestion time has a good reconstruction and expansion effect within the specified range.
