中文摘要：

为深入研究低能见度下影响驾驶人发生危险驾驶行为的因素,提高道路交通安全性,自编低能见度环境中危险驾驶行为问卷和驾驶能力问卷,用其对314名驾驶人进行调查。采用Pearson相关系数法和结构方程模型（SEM）建模方法,研究低能见度环境中危险驾驶行为与驾驶能力描述性变量间的关系。结果表明,低能见度环境中,驾驶人危险驾驶行为可分为错误行为和失误行为;性别与错误行为显著相关,且对错误行为影响最大的因素是危险感知能力,其次是低能见度事故,驾龄影响最弱;错误行为正向影响失误行为,且危险感知能力对失误行为有间接影响。

英文摘要：

In order to investigate factors influencing risky driving behaviors under reduced visibility conditions,and then to improve traffic safety,two questionnaires were complied,and a survey into 314 drivers was carried out by using the questionnaires. Pearson correlation coefficient method and SEM were used to explore the relationships between risky driving behaviors and driving ability in reduced visibility,and descriptive variables. The results show that risky driving behaviors under reduced visibility conditions can be divided into wrong behaviors and fault behaviors,that gender is significantly related to wrong behaviors,risk perception would be the most significant factor affecting wrong behaviors,followed by accidents happened under reduced visibility conditions,and driving experience would be the weakest factor,and that wrong behaviors have a positive effect on fault behaviors,and risk perception has an indirect effect on fault behaviors.
