| 摘 要： | 天气变化与交通事故之间存在较为密切的关系，利用2010～2018年南充市交通事故数据及相关气象数据等资料，探讨了不同气象条件对驾驶员、车辆、道路环境等的具体影响，统计分析了南充市所辖区域内交通事故年和月际、逐日变化和事故发生地当时气象要素特征，以及两者的相关性。结果表明:近年来交通事故呈现出逐年减少的趋势，主汛期(5～8月)和冬季是南充市交通事故的高发时期，而春季(3～4月)及秋季(9～11月)交通事故发生相对较少。同时，交通事故发生存在明显的日变化特征，每日07～08时、11～12时、14～15时、18～19时为高发时段；交通事故多发与天气条件具有一定的相关性，尤其是高温、降雨、大雾等天气现象；另外，在不同的天气条件下，有针对性的采取一些措施，可以有效避免交通事故的发生。
