This document contains the minimum requirements for maintenance practices applicable to traffic signals that will allow these installations to continue operating safely, reliably, efficiently and effectively for the duration of their economic service life. The traffic signal maintenance regime includes electrical, operational, structural and environmental aspects, covering both scheduled and unscheduled work. Maintenance practices for the electronic control aspects of traffic management (for example phasing, timing, sequencing, and the logic rack and electronic equipment) are also not addressed in this document.
