可變反光標記設計之研究

Feasibility Study of Changeable Pavement Markers

針對反光標記能夠結合的元素進行可變反光標記模型的設計，本研究藉由車道位置標示與路權的觀念結合於同一個交通設施之中，減少用路人需要觀看多個以上的交通設施才能獲得必要的用路資訊。配合現有交通管制的需求，本研究所設計可變反光標記，基本上可以區分為三個模組，其中模組一為雙綠燈反光標記，使用時機為當左右兩線車道皆為可通行時，作為車道之界線，以避免駕駛者偏離目前行駛車道。模組二則為紅黃燈反光標記，使用時機可作為中央分隔順向或逆向兩車道之左側標線上，亦可作為臨時調撥車道等使用，基本概念為改良目前黃色反光標記並加入紅色燈光以提高警示之效果。模組三則採綠白燈反光標記，使用時機可於道路最外側設置，用以區分道路和路肩的差異，以避免駕駛人偏離車道。由實際道路測試結果，紅黃燈模組二及綠白燈模組三在白天時，可能因為顏色的相互影響，遠距離時只能看到兩種顏色的重疊，駕駛者必須要縮短距離才可以清楚辨識，但仍可達到底限15公尺，其他各種情況則均在20公尺以上即可清楚辨識。

This study combines elements of pavement markers into the changeable pavement marker modules, involving the concept of lane position and right of way on the one transportation facilities to reduce the judgment upon more than one transportation facilities in the same time. The changeable pavement markers are designed base on the existing traffic rule, which basically can be divided into three modules, the first is a double green pavement markers, which be used at the left and right lanes both are accessible, and be used as the lane boundary to avoid the driver deviates from the current driving lane. The second module is red and yellow pavement markers, which be used at left side of a forward or reverse central divided lanes, and be used as temporary allocating of lanes, etc. The third module is green and white pavement markers, which be used at the right side of lanes to segment the road and shoulder, to avoid the driver deviates from the lane. The road testing results of study, can find the second module and third module probably because the interaction of colors during the day, the distance which can be clearly identified, just about 15 meters, which can reach the bottom criteria, the others of testing cases are more than 20 meters.
