Abstract

The research method is statistical in terms of data collection and analysis. Due to the fact that the present study seeks to design a model for the impact of natural factors in accidents on a section of the Nowshahr-Royan axis road (adjacent to the Si Sangan Coastal Forest Park in Nowshahr) in recent years, first citing meteorological organization statistics to examine the parameters Climate and its analysis is done and then using the statistics of road accidents and traffic passing in this part of the route, accidents caused by climate are examined. Thus, the data of the last three years of accidents, weather conditions and passing traffic are used for modeling. Analyzes, tests and statistical modeling were performed in the form of SPSS software. The results showed that the share of climate variables was such that weather conditions, rainfall and wind speed, temperature and horizontal visibility were the most important variables affecting the severity of accidents in the present study. So that this amount for the amount of precipitation is equivalent to a positive coefficient of 0.832, weather conditions are equivalent to a positive coefficient of 0.698, wind speed is equivalent to a positive coefficient of 0.066, temperature is equivalent to a positive coefficient of 0.027, horizontal visibility is equivalent to a positive coefficient of 0.022.
