摘要

本研究利用模擬駕駛實驗探討可變訊息標誌之中文字型（黑體，明體與楷體）與顏色（紅色，綠色與橙色）對受試者行車反應績效之影響。研究結果發現字型、顏色與兩者之交互作用對受試者之反應時間及反應正確率均存在顯著影響。就主效果而言，在中文字型上，受試者對黑體之平均反應時間優於楷體與明體，黑體與明體之正確率優於楷體；在字型顏色上，橙色與綠色之反應時間與正確率皆較紅色爲佳。在交互作用部分，發現不論字體型式爲何，受試者對橙色與綠色的反應時間均顯著較紅色爲佳，當顏色爲紅色時，受試者對楷體之反應正確率最差。本研究結果可提供高速公路可變訊息標誌中文字型與顏色設計之應用參考，進而提升駕駛之行車安全與效率。

This study examined the effects of Chinese font style (Hei, Ming, and Kai) and font color (red, green, and orange) of variable message signs (VMS) on participants' response performance (response time and accuracy) from an ergonomic viewpoint. Computer generated VMS stimuli merged with a driver's view driving video, were projected onto a screen while participants were making proper responses. The results showed Chinese font style and font color both were significant factors on participants' response performance. Participants took less response time for the Hei style than for the Kai and Ming styles, and exhibited higher accuracy for the Hei and Ming styles than for the Kai style. Participants responded faster and more correctly for the orange and green font color than for the red color. Additionally, the interaction of font style and font color also had a significant effect on participants' response performance. Response times for orange and green colors were shorter than for red color on each font style. Participants had the least correct for the Kai style in the red color. The findings of this study may assist in adopting suitable Chinese font and color on VMS and in improving safe and efficient driving for motorists on the freeway.
