摘　　要：对公路安全设计与评价方法进行了分析,提出了基于计算机仿真的公路安全设计方法。该方法以ADAMS(AutomaticDynamicAnalysisofMechanicalSystem)软件为平台,通过建立汽车、驾驶员和三维道路等系统仿真模型,为公路设计安全评价提供虚拟对象。在计算机上运行这些模型,获得汽车实时行驶速度,以此可以评价公路线形设计参数是否满足汽车行驶的要求,从而达到评价设计指标安全性的目的。该方法为公路安全设计评价提供了"活的数学模型",这些模型具有参数容易修改、数据表达直观、试验速度快和节省费用等优点。Highway safety design and evaluation has been discussed in this paper,authors put forward a method for highway safety design based on computer simulation,which is supported by ADAMS software. This method makes the virtual object available for highway safety evaluation with the construction of vehicle models,driver models and 3D road models on computers. Highway designers are allowed to study the relationship between the designed route parameter and vehicle motion and evaluate their safety by the real-time velocity which is acquired from the execution of these models on computer. This method provides some live mathematical models for highway safety evaluation,and the models have lots of advantages such as,convenience on model parameter adjustment,direct visual data display,high speed and saving of expense.
