Abstract:	行人過馬路的安全性，是「行人地獄」現象持續發燒的癥結。為了解決行人安全的問題，行政院於2023年5月25日通過「行人優先交通安全行動綱領」，除了透過教育、宣傳及加強執法來促進駕駛人的禮讓行為外，亦可搭配不同的交通設施管制方式來改善，例如調整行人燈早開的時制，以避免人車交織，減少碰撞機會。然而，路口交通事故又以夜間發生為主要，因此提升路口的可視性至關重要，使駕駛者能及早發現行人，有足夠的反應時間。本研究發現，在相同的路口條件下，白光在路口產生的對比度比黃光在路口產生的對比度高。以人因視覺分析角度來探討，不同色溫對於眼睛明視覺及暗視覺的刺激敏感度不同，因此將路口換為白光，確實能為駕駛者提供更好的緩衝距離，這也是目前桃園市養工處在易肇事路口的主要改善手段。同時搭配路段黃光、路口白光，使駕駛人在長途駕駛時較不易疲勞，並且可以在準備進入路口時直接感受到色溫變化，進而促使駕駛注意前方狀況。除了雙色溫路燈以外，本研究也量測在白光、黃光下，不同顏色反光貼紙的輝度值、不同類型的行穿線，以驗證最佳的設備搭配，提供後續路燈設計的建議。;The safety of pedestrians crossing the street is the crux of the ongoing issue of the "pedestrian hell" phenomenon. To address pedestrian safety, the Executive Yuan approved the "Pedestrian Priority Traffic Safety Action Plan" on May 25, 2023. In addition to promoting driver courtesy through education, publicity, and enhanced law enforcement, the plan also suggests various traffic control measures, such as adjusting the timing of pedestrian signals to avoid conflicts between pedestrians and vehicles, thereby reducing the risk of collisions. However, most traffic accidents at intersections occur at night, highlighting the importance of improving visibility at intersections. Better visibility allows drivers to spot pedestrians earlier, giving them sufficient reaction time.This study found that under identical intersection conditions, white light creates greater contrast than yellow light. From a visual ergonomics perspective, different color temperatures affect the sensitivity of the human eye to bright and low-light conditions differently. Replacing intersection lighting with white light has proven to provide better reaction distances for drivers. This is currently the primary improvement measure implemented by the Taoyuan City Engineering Department at high-accident intersections. The combination of yellow light for road sections and white light for intersections helps reduce driver fatigue during long drives. The change in color temperature as drivers approach intersections alerts them to the upcoming area, encouraging heightened attention to the road ahead. In addition to dual-color temperature streetlights, the study also measured the luminance of reflective tape in different colors under white and yellow light and analyzed various types of pedestrian crosswalks. This research aims to verify the optimal equipment combinations and provide recommendations for future streetlight designs.
