摘要:
根据遵义市高速公路各路段相近气象台站气象观测资料，分析了影响遵义市高速公路交通安全的主要恶劣气象因子特征，结果表明各路段的主要不利气象条件存在一定异同。相同点：各路段年平均夜间雨日比白天雨日多32d左右，上午雨日比下午雨日多15d左右；大雾天气以秋冬季节较多，雾主要发生在夜间到早晨；凝冻时段主要出现在12月下旬到2月上旬；大风天气总体不多；≥30℃高温天气主要出现7月至9月初，高温时段主要发生在12-17时；≤0℃低温天气主要出现12月至翌年2月，低温时段主要发生在夜间到早上。不同点：年平均雨日数西部路段多于东部路段；年平均大雾日数东部路段比西部路段多10d左右；凝冻影响比较严重的区域在习水周边，赤水河谷沿线极少发生凝冻；赤水至习水公路沿途的气温起伏大。讨论了恶劣气象条件对行车安全的影响，并给出了相应的建议。
Abstract:
According to the meteorological observation data of the weather stations near the highway of Zunyi, the characteristics of the main severe weather factors affecting the traffic safety of expressways in Zunyi were analyzed. The results show that: there were some similarities and differences of main unfavorable weather conditions of each section of roads. The common aspects: in each section, the annual average number of rain days at night was more than that in daytime about 32 days, the number of rain days in the morning was more than about 15 days in the afternoon; Foggy weather was more in autumn and winter, and the fog mainly occurred during the time from night to morning; Freezing periods occurred mainly in the late-ten-days of December to the first-ten-days of February; Above 30 ℃ high temperature weather mainly appeared from July to early September, and the high temperature period mainly occurred between 12:00 am and 17:00 am; ≤0 ℃ low temperature weather mainly appeared in December to next February, the low temperature periods mainly occurred from the late evening and to early in the morning. The different aspects: the number of annual average rainy days in the west is more than that in the east; the average annual fog days in the east were more than 10d than the days in in the west; Freezing influencing area is mainly concentrated in Xishui surrounding area, while the area along the Chishui River Valley is rarely frozen; the temperature of highway along from Chishui to Xishui changed violently. The influence of bad weather condition on traffic safety was discussed, and some suggestions were given.
