摘要: 利用2018—2022年辽宁高速交通事故、交通阻断数据及1971—2022年气象观测资料,分析不同气象要素对交通产生的不利影响。结果表明:降雨是诱发辽宁高速公路事故的主要天气因素,降雨日数与事故数的相关系数达到0.78。事故多发季节为夏季和秋季,多发时段为09—10时。低能见度事件和降雪是导致高速公路发生交通阻断的主要气象因素。阻断多发季节为冬半年,多发时段为18—23时。辽宁高影响天气日数及均值分布均呈现出一定的地区差异。京哈高速恶劣天气事故多发路段(532~552 km)主要受降雨和低能见度事件影响,低能见度事件日数较多且能见度均值较低,降雨日数较多且降水量较大。降雨和降雪日数呈减少的年代际变化趋势,低能见度事件日数在1986年以前呈显著减少的趋势,之后转为显著增长。

Abstract: Based on the data of expressway traffic accidents,traffic blocking from 2018 to 2022 and meteorological observations from 1971 to 2022 in Liaoning Province,this study analyzes the adverse impacts of different meteorological factors on traffic safety in Liaoning Province.The results show that rainfall is the primary weather factor leading to the accident of Liaoning expressway,and the correlation coefficient between the number of rainfall days and the number of accidents is 0.78.The accident-prone seasons are summer and autumn,and the time period is 9:00-10:00.Low-visibility events and snowfall are the main meteorological factors that lead to traffic jams on expressways.The main blocking season is winter,and the period is 18:00-23:00.The number and mean distribution of high-impact weather days in Liaoning Province show certain regional differences.The adverse weather accident-prone section of Jingha Expressway (532-552 km) is mainly affected by rainfall and low-visibility events.The number of low-visibility event is high and the average visibility is low.The number of rainfall days is high and the precipitation is heavy.The number of rainfall and snowfall days showed a decreasing trend,and the number of low-visibility days showed a significant decreasing trend before 1986,and then increased significantly.
