Recently, City of LOS ANGELES has completed a five-year LED replacement of all traffic lights and pedestrian signals.

According to Mayor Antonio Villaraigosa, the LEDs are about 85 percent more efficient than traditional lights, and the conversion will save the city about $4 million annually.

The city also is under the process of converting 140,000 of its about 210,000 street lights to LEDs, being financed by a $40 million loan by the Department of Water and Power. City officials expect that the new lights will save about $10 million a year after the completion.

The mayor announced the completion today of a traffic light synchronization program in San Pedro. The $7.3 million Automated Traffic Surveillance and Control project, which monitors traffic conditions and changes signals in real-time, linked 64 intersections and added 17 new left-turn arrows in the harbor area.
