引发公路交通事故的气象条件分析

利用1999~2003年间发生在丽水市境内的交通事故,并结合该地的气候特点,分析了引发交通事故的气象条件。结果表明:交通事故的发生与日照、雨量、最高温度、温差、能见度、相对湿度、雪深以及风速等有一定的相关性。另外夏季高温、冬季低温、高湿、雨、雪天气以及转雨日都很容易引发交通事故;秋冬季节的雾、雨天、雪天会使能见度降低从而引发交通事故;雨日比无雨日容易发生交通事故;交通事故的发生还与降雨量级有系,特别是大雨天最容易发生交通事故。夏冬季的晴天比阴天容易发生交通事故,而秋季阴天比晴天容易发生交通事故;结冰、积雪等天气尽管发生的次数较少,但引发的交通事故损失却非常大。

Analysis of Meteorological Conditions for Traffic Accidents

Based on the related data from 1999 to 2003 in Lishui,the correlation analysis of traffic accidents and weather conditions is conducted.The results show that traffic accidents are related to sunshine,rainfall,high temperature, temperature difference,visibility,humidity,snowfall,and wind speed.The traffic accidents occur more likely on high temperature days in summer and on low temperature days in winter,as well as on rainy,snowy,foggy days.The traffic accidents occur more frequently in fine days than cloudy days both in summer and winter,and vice versa in autumn.There are less relatively traffic accidents while the land is frozen up and covered with snow.
