Abstract:
Based on the monitoring data of meteorological stations, highway meteorological monitoring data, and the highway traffic information in Hebei Province from April 2010 to March 2013, the impacts of severe weather on highway traffic in Hebei province are analyzed. The results show: (1) 383% of highway traffic blocking events are caused by meteorological factors, among which the first factor is fogs and the second is snow; (2) the monthly change characteristic of traffic blocking resulting from fogs is most significant, and the occurrence frequencies in autumn and winter are obviously greater than those in spring and summer, and the influencing time is significantly longer in autumn and winter; (3) the annual average numbers of traffic blocking days resulting from fogs in the southeastern plains are greater than those in the western and northern mountain areas. Snow and ice are contrary; (4) through the analysis of a continual fog and haze process impacting highway traffic, a fog warning model of highway is preliminarily established, and some countermeasures of traffic meteorological service under the severs weather are put forward, which provides a reference for improving highway capacity in severe weather.
