高架橋不同綠美化方式對駕駛者產生生心理效益之差異

Effects of Different Viaduct Beautification Methods on Drivers' Psycho-Physiological Responses

本研究之目的在探討不同綠美化處理方式之高架橋對於駕駛者產生生心理感受之影響。利用電腦模擬影片的方式，模擬植栽綠化與油漆美化兩種高架橋綠美化方式，供受測者觀賞，然後收集受測者的生理（前額肌肌電圖及心跳）及心理（注意力測驗及狀態焦慮程度）反應資料。結果兩種不同綠美化處理之高架橋對受測者心理反應中之狀態焦慮有顯著差異，植栽綠化處理之狀態焦慮較低；其餘項目無達顯著差異。因此未來在進行都市地區高架橋綠美化工程時，可多利用植栽綠化方式柔化大型水泥量體剛硬的線條，藉以減輕駕駛者的心理焦慮感且達到道路安全之功能。 The purpose of this study was to explore both different ways to find the differences of two methods of beautification of urban viaduct in their effects on measure drivers' psychological (i.e., Necker Cube Pattern Control Test and anxiety levels) and physiological (i.e., electromyography and heart rate) responses. We used video simulation to present two beautification scenes of viaducts, one using vegetation and the other painting, to participating ”drivers”. After watching these simulations, the participants viewing vegetation had lower anxiety levels than those viewing painting viaducts. No significant differences were found in other items of psycho-physiological responses to the two treatments. Vegetation could play an important role in reducing the negative emotional impacts of viaducts.
