摘要：	The goal of this project was to collect the knowledge needed for the FDOT to either confirm or improve the adequacy of the FDOT’s existing minimum standards for lightning/surge protection, including devices used and installation procedures. The project was conducted in four (4) tasks: (1) State of the Practice/Best Practice Study and Literature Search; (2) Review of the IEEE Recommended Impulse; (3) Review of the Effectiveness of Lightning Termination Devices; and (4) Final Report. The research conducted for this project included surveys of FDOT districts and other state DOTs with similar lightning environments, literature searches to determine the proper techniques to test surge protective devices (SPDs) and best practice in designing lightning protection systems, design and construction of an SPD test laboratory, and analyses of NFPA 780 and other related standards with respect to the most appropriate standards to employ in designing lightning protection systems for FDOT roadside equipment. The results from this project included equipment and test procedures for an SPD test laboratory, recommendations for improved maintenance reporting to improve identification of lightning-related damage, and lightning protection system design recommendations. Implementing these recommendations will reduce the FDOT maintenance costs and improve the reliability of intelligent transportation system (ITS), traffic control, and roadway lighting equipment.
