Year: 2012

The Department of Public Works upgraded traffic signal mast arm street name signs using highly reflective non-illuminated technology that does not require lamps or electricity. This technology replaced energy consuming lamps in over 1,200 traffic signal mast arm mounted street name signs at over 400 intersections owned, operated, and maintained by Public Works in County unincorporated areas. The use of retro-reflective signs not only decreases energy consumption by 100%, it decreases maintenance resulting from burnt-out lamps. The innovative and cost saving technological change maintains the visibility of the directional signs to the driver without the need of costly electricity and maintenance. Both the decreased energy use and decreased maintenance contribute to energy savings and environmental conservation in Los Angeles County by reducing the demand for fossil fuels.
