Abstract:	本論文中，我們開發一道路照明量測系統，藉此評估道路照明與視覺效應，其中道路照明量測系統包含車載式量測儀與影像式輝度量測儀，其中車載式量測儀為將多組照度計、陀螺儀與車輪編碼器紀錄車頂上之照度分佈，透過演算分析計算出路燈之光強度分佈，並以CIE 140道路照明分析原則，即時計算出路面上之照度分佈。影像式輝度量測儀透過一系列之校正與修正流程，可用於量測路面之輝度分佈。此外，本論文提出一種快速路面反射率量測法，係透過影像式輝度量測儀在設定之距離下，藉由路燈之照明，可分析出路面之反射率分佈，並可計算路面之反射率表。本論文中，以影像式輝度量測儀應用於潮濕路面之反射率分佈，藉此分析LED與高壓鈉燈對於觀測者之視覺評估。;In this thesis, we developed a road lighting measurement system to evaluate the assessment of road lighting and visual effects. The road lighting measurement system includes an equipped vehicle and an imaging luminance measuring device. The equipped vehicle be used for measuring the illuminance distribution on the vehicle’s top which using illuminance-meter modules, a gyroscope, and a wheel encoder. Through algorithmic analysis, it calculates the light intensity distribution of the road light and the illuminance distribution on the road surface in-situ according to the CIE 140 road lighting analysis principles. The imaging luminance measurement device, through a series of calibration and correction processes, can be used to measure the luminance distribution of the road surface. Furthermore, this research proposed a fast method for measuring road surface reflectance. Using the imaging luminance measurement device at the specified distances and utilizing the illumination from the road lights, it analyzes the reflectance distribution of the road surface and calculates the reflectance table of the road surface. In this thesis, the imaging luminance measurement device is applied to measure the reflectance distribution of wet road surfaces, enabling the analysis of LED and high-pressure sodium lamps in terms of visual evaluation by observers.
