Analysis of traffic accident trends in Japan and predictions for the future

To date, numerical formulas for predicting trends in traffic fatalities have used the number of vehicles and total population as the main factors. This paper attempts to predict the trend in fatalities by means of numerical formulas that describe the relationships between decreases in traffic fatalities and three factors that influence these decreases: the social environment, vehicles, and human beings. This technique is then used to predict the number of traffic fatalities for the year 2020.
