Traffic Signals

Work on traffic signals falls into three general categories:

  • Preventative maintenance is performed on each traffic signal controller each month. the intersection is walked around checking pedestrian push buttons and visually checking the intersection for needed repairs on a weekly basis.
  • Signal heads are inspected and cleaned once each year. While inspecting the LED lamps, the lenses and refractors are cleaned, and the alignment of the lights is checked, along with the condition of the pole.
  • Trouble calls for accident damage or malfunction are answered as they come in during working hours. After hours, calls are handled according to a priority system set up by Maintenance personnel. Some are responded to immediately and some are left on flash until the following morning or through the weekend. Troubles range from lights being out and detectors malfunctioning in the streets to electronic failures in the cabinet.
