  1. 利用2015年12月至2018年11月河北省高速公路交通事故资料及气象观测数据开展了两者间的定量关系研究。河北省高速公路交通事故呈夏秋季明显多于冬春季、白天明显多于晚上的时间变化特征,其中8月、10月,09:00—11:00、14:00—17:00分别是月际变化和日变化的高峰时段;石家庄藁城区和唐山丰南区为高速公路交通事故发生最多区(县)。以石家庄地区为代表,利用Spearman秩相关和曲线拟合分析了高速公路交通事故发生起数与不同气象要素的响应关系,发现高速公路交通事故发生起数对气温的响应存在明显阈值效应,日平均气温、日最高气温、日最低气温的阈值分别为20 ℃、25 ℃和15 ℃。日最小相对湿度超过80%时,每上升1%,事故发生的相对危险度增加3.77%;日最大小时降水量每增加10 mm,事故发生相对危险度增加18.8%;当能见度低于1000 m时,能见度每增加100 m,高速事故发生相对危险度减小4.14%。

Abstract: Based on traffic accidents and meteorological observation data from December 2015 to November 2018 in Hebei Province, the quantitative relationship between highway traffic accidents and meteorological conditions was analyzed. The highway traffic accidents happened more in summer and autumn than in spring and winter, and they happened more in the daytime than during nighttime. The peak value appeared in August and October, and it appeared during 09:00-11:00 and 14:00-17:00. Highway traffic accidents in Gaocheng of Shijiazhuang and Fengnan of Tangshan occurred most. Take the case of Shijiazhuang area, the response of the relative risk RR of highway traffic accidents to different meteorological elements was analyzed using the Spearman rank correlation and curve fitting method, it was found that there was a significant threshold effect of temperature on the frequency of highway traffic accidents, and the threshold of daily average temperature, the daily maximum temperature and daily minimum temperature  were 20 ℃, 25 ℃ and 15 ℃, respectively. When the daily minimum relative humidity exceeded 80%, the relative risk of accident increased by 3.77% for every 1% increase of relative humidity. When the maximum rain intensity increased 10 mm·h-1, the accident risk increased by 18.8%. When the visibility was less than 1000 meters, the risk of highway traffic accident decreased by 4.14% with the increase of 100 meters in the visibility.
