Each year, about 1.35 million people die as a result of traffic accidents in the world. The 2030 Agenda for Sustainable Development also has set an ambitious target of halving the global number of deaths and injuries from road traffic crashes by 2020 [1]. In Japan, Aichi Prefecture has the most traffic accidents by a prefecture for 16 years until 2018. Aichi Prefecture arose the goal "By 2020, reducing the annual number of traffic fatalities within 24 hours after an accident to no more than 155" in the 10th Aichi Prefecture Traffic Safety Plan released in 2016 [2]. In this paper, we analyze the relationship between the number of accidents and traffic volume in Aichi Prefecture to reduce traffic fatalities. In this analysis used the latest traffic accidents data including 2019. As a result of the analysis, we found some relationship between them. Furthermore, we find the possibility of a rapid increase in the number of traffic accidents when the traffic volume exceeds a certain criteria. We will estimate the criteria near future.
