本研究利用排序選擇模式探討汽車駕駛者對行車中使用行動電話之安全認 知，並分析駕駛者對政府立法禁止行車中使用行動電話的態度。本研究以電話隨 機抽樣訪問臺中縣市400位汽車駕駛者。研究結果發現受訪者認為行車中使用手 持式行動電話之交通事故風險高於使用免持聽筒。但不論使用手持式或免持式行 動電話，受訪者認為在高速公路與一般道路上之行車事故風險差異不大。受訪者 支持禁止汽車駕駛者於所有道路行車中使用手持式行動電話的立法，尤其是女 性、已婚且有幼童、及不常在行車中使用行動電話者。本研究最後從立法、教育、 執行、及技術等層面提出建議，供政府相關主管機關參考。

　　　　　The ordered probit models were used to determine the preferences of car drivers on safety perception of using a cellular phone while driving and attitudes toward legislation against the use of a cellular phone in a moving vehicle. This research conducted a telephone survey and randomly selected 400 car drivers in Taichung area. The results indicate that drivers perceive that using a hand-held phone in a vehicle has an increased risk of having a traffic accident, compared to drivers who use a hands-free phone. However, the difference of perceived risks associated with drivers using a cellular phone while driving on freeways or arterial roads is insignificant. Drivers, who are female, married with young children, and less frequent use of cellular phones while driving, are likely to support the laws that ban the use of hand-held cellular phones while driving. Implications on regulation, education, enforcement and technology are discussed.
