| Outline of Final Research Achievements |
The relationship between relative accident ratios (per quasi-induced exposure) and age was examined using cohort analysis for drivers involved in traffic accidents from 2001 to 2012. The ratios were calculated by 5 human factors causing traffic accidents and 8 birth-cohort. The rations were the lowest around 40 to 55 years old and increased according to aging. The relationship between the ratio and age was almost the same for 8 birth-cohort excluding 'distracted driving'. The relative arrest ratio (per quasi-induced exposure) increased with aging also.
A driver is likely to be involved in traffic accident with the same human factor with which he was involved in traffic accident before. Similarly, a driver is likely to be arrest for the same violation type. It is hard for those drivers to change their driving manner or safety awareness. Therefore, the safety measure that make those repeated accident/violation drives change their driving manner and safety awareness is important.
