In these years, road accidents have become an important issue. The accidents costs estimate up to ۳% of countries' GDP. There are many important reasons that can influence accidents rate. In this study, ۱۲ factors have been explored and the logistic regression model is used for predicting slight or serious/fatal accidents. The results from logistic regression show ۸۸.۴۸% of accuracy and can be a useful method in providing meaningful interpretations for organizations that are involved in these issues like police departments for future safety improvements. By using this model the probability of slight or serious/fatal accidents can be predicted the accidents' incidence
