摘　　要：交通安全性是公路设计的核心关注点。尽管相关安全规范对这一问题已有明确的规定,但每个工程项目都有其独特性,无法完全涵盖所有情况。因此,引入了一种新方法,从车辆失控的关键原因——轮毂温度出发,通过分析大型货车轮毂温度上升的机理,优化平面和纵向道路设计,以降低车辆失控事故的发生率,从而提高道路行驶的安全性。需要指出的是,所提出的理论仍有待完善,未来将通过大量的试验和验证工作进行优化。研究成果为交通工程师们提供了一个参考方向。Road safety is a core concern in design of highway.Although relevant safety regulations have provided clear guidelines for this issue,each project has its unique characteristics,the regulations cannot cover all scenarios completely.Therefore,in the paper,a new method is introduced which originating from the key cause of vehicle loss of control-the wheel hub temperature.By analyzing the mechanism of hub temperature increase in large trucks,this study aims to optimize horizontal and vertical road design so as to reduce the incidence ratio of accidents due to out of control of vehicles,and thereby enhance the safety of road travel.It should be noted that the theory proposed in this paper still needs to be improved,and more experimental and validation work in the future need to be conducted for optimization.This study offers a reference direction for traffic engineers.
