高影响天气对辽宁省高速公路交通安全影响研究
Study on the impact of adverse weather fonditions on expressway traffic safety in Liaoning Province
摘要
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 meteoro-logical 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 ex-pressways.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.关键词
