為了降低高齡駕駛者交通事故的嚴重度與發生可能，先前研究多針對交 通安全事故影響因子或駕駛行為進行探討，將焦點放在高齡駕駛者本身。本 研究不同於以往，係以高齡駕駛者之「家庭成員」作為研究的切入點，透過 臺南市老人福利團體為媒介，發放日常行為問卷給臺南市高齡駕駛者之家庭 成員填寫，共回收407 份有效問卷，並以相關統計驗證方法得到假設驗證成 立之結果。本研究據以建立簡易版「臺南市高齡者日常行為問卷」二套和問 卷總得分對照表、分別推估潛在交通事故發生次數與潛在受傷程度的機率。 本研究建立之日常行為問卷，可引導家庭成員與家中高齡駕駛者一同正視高 齡者安全駕駛的重要性，本研究結果將提供給有關單位在發展交通政策時作 參考。

To improve traffic safety problems of elderly people, previous studies aimed at factors relating to traffic fatality and driver behavior, usually focusing on elderly drivers themselves. Unlike previous studies, this paper adopts a different approach by investigating perspectives of elderly drivers’ family members. An elderly driver Everyday Behavior Questionnaire (EBQ) was developed and answered by their family members. The effective sample size throughout Tainan City for this study is 407. Statistical analyses and hypotheses tests are satisfactorily conducted. Based on the findings, two sets of simplified EBQs are generated especially for elderly drivers in Tainan City that would indicate the probability of involving in traffic crashes and the potential accident severity. With these easily applied EBQs, it is expected that family members would serve an important role in promoting traffic crash prevention for the elderly drivers.
