Reconsideration The Relationship Between The Rapid Aging of The Societies and The Older Driver's Traffic Accidents

The purpose of this paper is to reconsider the relationship between the aging society and the traffic accidents by older drivers, so it is possible to establish suitable policies for the society. We estimated the changes of the traffic accident rate considering the number of drivers. Also, we analyzed the effect of traffic accidents classified by age. It showed that the accident rate of the older drivers decreased over time, and also that the older drivers have the effect of decreasing the number of traffic accident and the number of deaths in traffic accidents. Due to the analysis on simple accident data and the older drivers' physical frailty, it was generally thought that older drivers increased the accident rate. Therefore, policies should be devised to limit the older drivers' driving. However, our study concludes that traffic policies must be established considering the behavior of the older drivers.
