Road accidents and casualties are one of the main causes of death worldwide, which has imposed a lot of economic costs on the economies of the countries.Four human, vehicle, road and environment factors are involved in the road accidents, among which, the environmental and climatic factors account for a significant share.The components of "frost, humidity and temperature" are among the most effective climatic factors that play a major role in road accidents.Therefore, the present study has been conducted to analyze the distribution of road accidents leading to death with climatic approach in different seasons of the year using Geographic Information System (GIS) in Ardabil province.The research method is descriptive-analytic.ترجمهSince the crash is a spatial phenomenon and Arc GIS analyses are also location-based, GIS and Kriging's interpolation method have been used for analysis.In this research, road accidents in Ardebil province in different seasons of the year and considering the climatic factors of freezing, temperature and humidity in the time period from 1389 to 1393 have been studied.The results of this study show that out of 762 accidents, 35% happened in summer, 25.75% in the spring, 24.55% in autumn and 14.7% in winter.The comparison of the diagram of accidents leading to deaths based on the months of the year, with the diagram of days of frost in Ardebil province indicates that road accidents in Ardebil province during the freezing months are lower due to the reduced traffic of tourists' vehicles compared to non-frosty months. Most of the accidents have occurred with a moisture content of 69-72% in terms of humidity, and at very low temperatures of 8 degrees Celsius and very high temperature of 16 degrees Celsius in terms of temperature.
