| Outline of Final Research Achievements |
We evaluated the effect of a cognitive test at license renewal for license holder aged 75 years or older, and found no significant effect on their crash risk but increased traffic injuries among older unprotected road users following the introduction of the test. This risk increase is possibly due to modal shift from driving to non-driving among older drivers. We also evaluated the impact of driving cessation among older drivers on their health, using cohort data, and found increased risk of functional limitations among those who stopped driving.

| Academic Significance and Societal Importance of the Research Achievements |
近年、高齢運転者対策がますます強化され、社会的にも高齢者に運転中止を促す機運が高まっているが、その負の影響についてこれまで見過ごされてきた。高齢運転者は運転をやめれば事故を起こさなくなるが、運転者から歩行者などの交通弱者に立場を変え事故に遭ったり、社会的に孤立したりする可能性がある。本研究ではそれらを実証することで、現行の高齢運転者対策に一石を投じた。
