Road Traffic Accident Involvement Rate by Accident and Violation Records: New Methodology for Driver Education Based on Integrated Road Traffic Accident Database

A new database system was developed by integrating the license data of all drivers in Japan (80 million drivers) with 11 million road traffic accident data from the year 1995 to 2007 and 130 million road traffic violation data from the year 1993 to 2007 to study the relation between accident/violation experience and accident rates. The results of data analysis using the database are as follows; 1) There is a relation between the number of accidents/violations in the previous 5 years (from the year 2002 to 2006) and the accident involvement rate in the year 2007. 2) The more accident or violation records is, the higher the accident involvement rate is. This relation is observed in male and female, all age groups and most of prefectures (regions). 3) Analyzing a relation between each violation and the accident involvement rate, there is a strong correlation between the number of disregarding traffic signal and the accident involvement rate. Though the conditions of road traffic accidents and traffic violations differ in prefectures, driver education can be improved by considering these conditions and the relations between accident or violation experience and accident rates mentioned above.
