本研究參考過去國內外文獻與高齡行人肇事事故資料，分析影響風險感認相關變數、高齡行人產生不安全行為特性與影響變數。並且嘗試以結合科技接受模式與計畫行為理論為基礎，描述行人倒數計時號誌透過心理層面主要影響因素，進而產生不安全行為。依此架構發展高齡者風險感認與高齡者不安全行為量表。以結構方程試驗證本研究潛在變數之間因果關係假設是否成立。本研究於民國97年3月至4月期間於北部地區高齡者活動較頻繁的路口，例如學校、醫院、公園等附近的十字與T字路口進行調查。最後將以敘述性統計、群集分析、結構式方程等方法進行資料分析與統計檢定。結果發現行經行人號誌與一般號誌相對風險認知程度沒有差異，但是行為意向有顯著差異。低風險感認較高風險感認容易產生不安全行為，尤其以行經行人倒數計時下低風險感認集群較容易產生不安全行為。知覺行為控制為重要中介變數，知覺行為控制(0.504)是唯一直接影響行為意向，態度間接(0.132)影響行為意向。主觀規範對行為意向沒有直接影響與間接影響影響。 We used Combined TAM and Theory of Planned Behavior (C-TAM-TPB) to discuss the relationship between the perception of elders' risk and unsafe behavior with count-down pedestrian signal. Risk perception is one of the key factors that affect the decision of behavior. The survey was conducted by interviewing the elders pedestrian in Taipei during March of 2008. Several statistical analysis tools were employed in this study, including descriptive statistics, multivariate statistical analysis, structural equation models. The study results showed the elder's risk perception tested to have no difference between the elder's pedestrian who crossing intersection with count-down pedestion signal or only with traffic signals but have significant different of the elder's behavior. The elder who crossed intersection with count-down with lower risk perception will occur unsafety behavior more easily. The study results of the Structural Equation Model (SEM) showed that perceived behavior control is the most dominate factor in the elder's unsafe behavior mode and its weight is 0.504. the next factor is attitude which indirect effect weight is 0.132. The last factor is subject norm which have no direct effect and indirect effect.
