摘　　要：对单侧加宽旧路通行问题进行分析,建立车辆换道和力学状态模型,从车辆换道时的转弯半径、轨迹长度和横向力系数的角度对单向双路拱路面的行车安全性进行研究,对中央分隔带拆除后连接两幅旧路的施工方案可行性进行论证。从结果上看,车辆换道时的各项指标均满足要求,连接两幅旧路的施工方案具有一定的可行性。Thepaperanalyzesthetraffic problemsofthe old road widened on one side,establishesthe lane change and mechanical state models of vehicles,studies the driving safety of one-way double-arch road surface from the angle of turning radius,track length and lateral force coefficient of vehicle lane changing.According to the results,the indexes of lane change meet the requirements,and the construction scheme of connecting the two old roads has certain feasibility.
