Maintenance is one of the keys to safe and effective traffic signal operations. Municipalities should be fully aware of their liabilities and their duty to provide safe travel to roadway users. Studies show a significant reduction in response or emergency maintenance calls after implementation of preventive maintenance programs.

This webinar will focus on the fundamentals of traffic signal preventive and response maintenance and why these efforts help agencies improve operations, promote safety, and preserve their infrastructure. Guidelines on documentation and minimum requirements for preventive maintenance will be presented.
