Based on the highway traffic accidents data and the meteorological observations from the traffic automatic meteorological stations and weather stations during 2008-2012 in Hebei Province, the diurnal, monthly and annual variation characteristics of traffic accidents percentages and their relationship with the disastrous weather such as rainy, snowy and foggy weather were analyzed. Then considered the meteorology, road network, traffics and terrain factors, the early warning indexes system of highway traffic under foggy weather condition in Hebei Province was established by using the experts marking and index weight methods. And combined with the traffic accidents in Hebei of Beijing-Shanghai and Huanghua-Shijiazhuang highways during 2013-2014, the warning indexes system was tested. Results showed that the annual frequency of highway traffic accidents in Hebei Province had large change during 2008-2012, and it appearred a downward trend in the whole. The daily change of traffic accidents was obvious, and the frequency of traffic accidents from 00:00 to 08:00 was the most, followed by 11:00 and 16:00. The monthly frequency of traffic accidents displayed a single peak change, in July it was highest, followed by June, May and August, while in December it was lowest, therefore the traffic accidents in summer was the most, the percentage was 30.2%, and in winter it was the least, the percentage was 20.2%. The traffic accidents caused by disastrous rainy, foggy and snowy weather frenquently occurred from May to September, September to the next March and December to the next February, respectively. And the traffic accidents under foggy weather condition often occurred from 06:00 to 08:00. The accuracy rates of the operational warning in Hebei section of Beijing-Shanghai and Huanghua-Shijiazhuang highways during 2013-2014 were respectively 84% and 75.9%, which was higger. The early warning indexes system could provide reference to traffic weather service and disaster prevention and mitigation in Hebei Province.
