摘要
城市道路施工区交通事故频发,很有必要对事故发生的成因进行分析。通过分析总结施工区合流强制性、速度离散性和环境复杂性等影响交通安全的因素,引进突变理论分析人、车和道路环境对交通安全相互作用的机理,最终构建燕尾突变模型。该模型能够对施工区交通事故的形成进行新的阐述,具有显著的现实作用。
It is necessary to analyze the cause to accident when there are frequent traffic accidents in the urban road construction area.By analyzing &summarizing the factors affecting traffic safety,such as coerciveness,speed dispersion and environmental complexity in construction area,the paper introducescatastrophetheory to analyze the mechanism of interaction between people,vehicles and road environment on traffic safety,and finally constructs a dovetail mutation model.The model can make a new exposition of the formation of traffic accident in the construction area and has a significant realistic effect.
