• Abstract:
  In this project, photoluminescent stones and solar photovoltaic modules by Wattway were investigated as a means to provide lighting to pedestrian areas and heavily trafficked roadways/pathways. The photovoltaic modules by Wattway were not able to be delivered as scheduled because of manufacturing defects and thus this phase of the project was put on hold. Three largescale photoluminescent stone installations were installed; two at the Florida Department of Transportation’s (FDOT) Traffic Engineering Research Laboratory (TERL) facility and one at the University of Florida. The stones that were used were supplied by Ambient Glow Technologies and were selected from a large number of potential suppliers. Based on assessment of their luminance and slow decay times, these stones were deemed the most promising to provide light for the longest duration possible; under controlled laboratory conditions, the stones were visibly emitting light for over 12 hours. At TERL, the stones were utilized in concrete and asphalt pathways that were 150-ft. and 200-ft. in length, respectively. Overall, both installations indicated that the stones were stable and no notable degradation in performance was observed. However, because of the ambient lighting at TERL, assessment during the night was difficult and led to the construction of a 30-ft. installation at the University of Florida, where stenciled designs were implemented. Overall, results indicate that the emerald green stones from Ambient Glow Technology provide lighting capable of being observed, albeit faintly, for the duration of the nighttime. Further research should be completed at a larger scale to determine the effect of vehicular travel, driver awareness/human factors and target value for pedestrian or other trafficked pathways. Further, an evaluation of surface integrity with respect to particle attrition and raveling and/or delamination are not well understood.
