基于车路协同的山区道路交通安全预警模型研究

Research on Traffic Safety Forewarning Model of Mountainous Road with Car-way Synergy

山区道路山高坡陡,车辆安全评价指标复杂多变。系统分析影响山区道路安全的人、车、路、环境等因素,运用聚类分析法构建评价体系;结合单因素评价模型、转弯车速安全性评价模型和多因素综合评价模型,建立基于车路协同的道路交通安全预警模型。实例研究表明该模型可准确评估道路行驶安全度,为道路的安全适应性评价提供一种有效、简捷的方法,有效减少道路交通事故的发生率。

Mountains are high and slopes are steel in mountainous road. The indexes of vehicle safety evaluation are complex and changeable. Factors which affect the safety of mountainous road such as people,vehicles,roads,environment and so on are systematically analyzed. Cluster analysis method is used to build evaluation system. Combining the single factor evaluation model,cornering speed safety evaluation model and multi factor comprehensive evaluation model,a road traffic safety forewarning model based on car-way synergy is established. The case study shows that the model can accurately evaluate the safety degree of road travel and provide an effective and simple method for evaluating road safety adaptability,which can effectively reduce the incidence of road traffic accidents.
