Implementation of Backup Power for Traffic Cabinets During Extended Power Loss

Objectives and associated tasks of the project are as follows: 1. Expand the literature review conducted in project BE703 to include additional backup technologies that became available in the last two years. 2. Perform additional research on the topic of battery life cycle, especially with newer chemistries like lithium-ion or lithium polymer batteries. 3. Research how many solar panels are adequate enough to charge a battery and if they can be installed at a signalized intersection and provide solutions. 4. Conduct pilot deployment of a selected backup system from a selected technology with a local agency and monitor degradation of the charge provided by the product including the solar panels. 5. Conduct a benefit-cost analysis for a selected backup system from a selected technology.
