高齢者の運転免許更新講習データからの運転能力変化の傾向分析

抄録

People aged over 70 are required by law to participate to the elderly training course for license renewal. However, we have never done firmly a follow-up of the relationship between license continuity and driving characteristics. Therefore, in this study, we tracked the training data and classified the elderly on whether they participated the next training after three years. And, we compared the driving aptitude test data of participants and non-participants. The driving aptitude test consists of a selection response test and a multiple operation test. There was no significant differences in each group for “Selection response test”. But, variance of non-participants group was significantly increased for “Multiple operation test”. From the fact that such differences appear only in “Multiple operation test”, there was a tendency among the non-participant group to include more people whose attention allocation capability have been reduced. However, the reaction time had large individual differences. Therefore, it was not possible to conclude the driving characteristics of the elderly from only the statistical analysis.
