我国是交通事故频发的国家,交通事故率和事故的严重程度已居世界首位,随着人们生活水平的提高,交通安全问题已成为人们最关心的问题。分析了道路交通事故产的主要原因和道路线形与道路交通事故的关系,提出了用布劳斯曲线改进道路曲线的设计方法和道路线形设计的核查方法,以满足行车的力学性能,同时满足线形连续、指标均衡、视觉良好、景观协调、安全舒适等要求,使道路曲线与地形和车辆的行驶轨迹达到完美的组合。
China is a country with frequent traffic accidents. The traffic accident rate and the severity of accidents have become the highest in the world. With the improvement of people’s living standard, traffic safety has become the most concerned issue. The main causes of road traffic accidents and the relationship between road alignment and road traffic accidents are analyzed. The design method of road curves and the checking method of road alignment design with Braus curve are put forward to meet the requirements of traffic mechanics while satisfying the linear Continuous, balanced indicators, good vision, landscape coordination, safety and comfort requirements, the road curve and the topography and vehicle trajectory to achieve the perfect combination.
