Based on the data of traffic accidents in Guizhou from 2014 to 2016, the general survey of traffic meteorological disasters and the climatic statistics of Guizhou from 1981 to 2010, the climatic conditions of disaster-causing meteorological factors such as low visibility, road icing, short-time heavy rainfall and rainstorm and their impacts on traffic safety are analyzed. The mileage of G60, G75 and G76 national highways in Guizhou, which are low visibility and easy to freeze, account for 7.0% (28.6%), 29.4% (17.1%) and 25.2% (7.8%) of the total mileage, respectively. Bridges and tunnels in susceptible areas account for 69.2% (80.4%), 87.5% (55.3%) and 53.1% (27.8%) of susceptible sections, respectively. Based on the above research results, the construction layout of traffic automatic weather stations in Guizhou Province is optimized, and the construction ideas of all-factor and non-all-factor traffic automatic weather stations are put forward. According to the distribution of low visibility, road icing, short-time heavy rainfall and rainstorm, the construction density layout is proposed, with a view to providing limited funds, to monitor traffic meteorological conditions more efficiently.
