Variance of Drivers' Risk Recognitions and Occurrence of Traffic Accidents

Abstract

Vehicle-to-vehicle type collisions, which make up 80% of traffic accidents, are considered to be the result of nonconsistent behaviors of conflicting divers due to their differences in risk recognition about any particular spot. With this research, the hypothesis that risk recognition difference has positive effect on the accident occurrence has been proven by constructing models of a traffic accident occurrence. In addition, from results of this research, the occurrence of traffic accident highly fits to Poisson distribution, and non-agreements of risk recognition for some reasons don't have positive effect on accident occurrence.
