How San Diego’s Smart City Tech Is Reducing Traffic, Saving Energy


February 27, 2017

San Diego is rolling out the largest city-based Internet of Things (IoT) network in the world, with deployment 3,200 smart sensors to upgrade the city’s infrastructure and enhance the quality of life for residents, announced San Diego Mayor Kevin Faulconer at a press conference.

The city is partnering with GE and will deploy its digital engine for intelligent environments called “Current” and replace 14,000 streetlights with energy-efficient LED versions, reducing the cost for energy by 60 percent, light pollution and overall greenhouse gas emissions (GHGs). A portion of the city’s traffic-light system, 3,200 lights, will have sensors connected to a digital network that can optimize parking and traffic, enhance public safety and track air quality.

This digital streetlight network may be doubled in the future, according to David Graham, deputy chief operating officer for the city’s Office of Neighborhood Services, who was a speaker at a ULI San Diego-Tijuana breakfast program on January 14, “Riding the Wave of Disruptive Technology.”  He noted that 3,200 streetlights have already been replaced with LED lights and computerized to optimize traffic flow during rush hour. With the additional upgrades to LED, there will be a total of 20,000 LED streetlights, covering 160 miles of city streets.

The ULI breakfast program, which was moderated by Heather Foley, executive director of San Diego ULI-TJ, brought Graham together with other local leaders in Smart City technology to discuss how the city is applying IoT technologies to advance the city’s Climate Action Plan goals, improve quality of life all residents, and accommodate future growth.
