Abstract:

This research study investigated the applicability of backup power systems to provide extended backup power to traffic signals after power loss due to hurricanes. CUTR researched available and experimental technologies and recommended three systems for testing to the Florida Department of Transportation (FDOT). The three selected systems were acquired and installed at a test intersection at the FDOT Traffic Engineering Research Lab (TERL) in Tallahassee. A liquid propane generator was tested that successfully provided constant power without issues; the only limitation was the availability of fuel. A lithium battery system also was tested, which powered the test signalized intersection for 20 hours, more than enough to cover nighttime operations. A system that included a battery + solar backup was tested successfully and provided power for several days without issues. This system uses smaller battery capacity but requires sunny weather to charge the battery and power the intersection during daytime; this is not usually an issue after hurricanes, especially if adequate solar energy generation is provided to charge the battery during available daytime hours. These systems are recommended to be approved and placed on the FDOT Approved Product List (APL) for future use by agencies in Florida.
