摘　　要：为了避免由于线形设计不良造成日后事故多发路段的产生,提出了基于人-车-路虚拟试验的道路线形设计安全性评价方法。首先基于对公路线形导致交通事故的分析,选取并构造了轨道跟踪误差、转向任务间隔、方向盘峰值转速、侧向加速度、垂直荷载和路段通行极限车速为道路线形安全性评价指标;采用EICAD和多体动力学软件ADAMS/Car实现了道路设计方案的三维建模,然后与车辆模型、驾驶员模型构成仿真环境完成了对安徽至浙江某高速公路线形设计方案的安全性评价;多数评价指标显示该设计路线安全性较好,但路段通行极限车速显示该路段前段（里程0~2.47 km）行车速度分布较分散,容易诱发超速行驶,为潜在的事故多发路段。To avoid accident black-spot due to defective alignment design,a new way of safety evaluation of road alignment based on human-vehicle-road virtual test is proposed.Firstly,according to analysis on various traffic accidents due to road alignment,evaluation index are composed consisting of route trac-king error,steering task interval,steering wheel speed peak,lateral acceleration,vertical load and speed limit.Then,by using EICAD and multi-body dynamics software ADAMS / Car,the three-dimensional model of road design is visualized.Plus with virtual vehicle models and driver models the simulation environment is finally set up to evaluate the safety of road design which is from Anhui to Zhejiang.Most evaluation indexes show that the road alignment design is overall safety,while in preceding section of the road（Mileage 0~2.47 km） car speed varies in a relatively big range,which has increased the possibility of speeding,thus this section of road can be a potential accident black-spot.
