摘　　要：为消除目前公路改建设计存在的盲目性和随意性,将安全性和舒适性2大基本原则贯彻到公路改建设计过程中。以四川省泸定县猫磨路改建工程为例,用公路-驾驶人-车辆-环境仿真系统模拟不同驾驶模式下,车辆在各路段设计方案上的行驶过程。通过仿真输出的速度、轨迹、转向盘转速和横向加速度等行驶响应参量,描述、衡量和分析路线方案行驶安全性和舒适性,并据这两者调整路线的几何参数设计,直至得到满意的路线方案。In order to eliminate aimlessness and casualness in current reconstruction designs of roadway, principles of safety and comfort were applied to roadway reconstruction designing and the advancement of this method was tested through design quality of reconstruction route. A certain double lane mountainous road in Sichuan, China, was selected as the object of study. Driving a vehicle on a designed road was sim- ulated by a ＂driver-vehicle-environment＂ system. Using the respond parameters such as speed, trajectory, rotate speed of steering wheel and lateral acceleration, the levels of safety and comfort of the designed road were measured, and then the geometry elements of road were repeatedly modified until the satisfied align- ment was obtained.
