消費者在購買新、舊車的同時，除了考量車輛的安全性能外，車色亦為考量重點，而令人注意及好奇的是，有許多報章媒體報載與一般民眾的認知，認為車色在道路交通安全上可能有部分的關聯，例如白色或淺色車輛較為顯眼，因此以駕駛人視覺角度，其安全性相對黑色或深色車輛來得高。惟就上述相關的資訊及認知，國內目前尚無相關文獻及研究資料佐證。為探索各車色間的差異與道路交通事故關聯性與否，本研究蒐集臺北市105年及106年所有道路交通事故，並抽樣分析自小客車碰撞自小客車之兩車交通事故案件，利用區域經濟學區位商數的概念，比對及分析不同車色分類間事故風險相對程度的差異。結果顯示黯淡色系及黑色系車輛的涉入交通的事故風險相對於白色系、黃色系及明亮色系車輛來得高。此外，以駕駛人視覺上顯眼度的角度觀之，追撞事故之發生可能與駕駛人視覺較有關聯，而在視線良好的情況下，黃色系車輛的事故風險相對其他車色分類來得低，同時黯淡色系車輛的事故風險則相對其他車色分類來得高，而在駕駛人視線受到雨天或光線昏暗等因素的影響下，明亮色系車輛的事故風險則相對降低，同時黑色系車輛的事故風險則相對提高。

When consumers purchase new or used vehicles, they will consider the safety performance of vehicles. They also focus on colors of vehicles in particular. It is curious that according to newspaper and the cognition of the peoples may have the following associations to road safety, for example, white or light-colored vehicles are more conspicuous. From a visual point of view, their safety is higher than dark. However, with regard to the above-mentioned related information, there is currently no relevant literature and research data supporting it. In order to explore the relevance of differences in vehicle colors with road traffic accidents, the study collected the traffic accidents data in Taipei from 2016 to 2017, and conducted sampling analysis in the type of two-cars collision by using the concepts of economics Location Quotient to compare and analyze the differences in the relative degree of accident risk among different vehicle colors. The results show that the risk of traffic accidents in dark-colored and black vehicles is higher than white, yellow, and bright-colored vehicles. In addition, from the perspective of the driver's visual, in the case of a good sight, the accident risk of yellow vehicles is lower than other vehicle colors. At the same time, the accident risk of dark vehicles is relative higher than other vehicle colors. Under the influence of factors such as rain or dim light, the accident risk of bright colored vehicles is relatively reduced, while the accident risk of black vehicles is relatively high.
