Abstract: This study analyses the road accident data with the aim to predict the probability of road accidents leading to death and determine the affecting factors. Regression models including logit, probit, complementary log-log, gompertz and decision trees based on the CART algorithm were used to analyse the actual data of the rail road police centre of the country. The results show that the logit regression model is superior to the other models from the perspective of the scales of the health indicator. Also, the variables of day of week, age, shoulder path, road side, road type, road position, maximum speed, belt safety, specific safety equipment, vehicle type and vehicle manufacturer country are among the variables that significantly affect the probability of road deaths, and can be controlled by controlling their levels.
