Mayor Faulconer, Councilmember Zapf Announce City’s Smart Traffic Signals Are Shrinking Commute Times

New Innovative Technology Optimizes Traffic Signals, Reducing Travel Time Thanks To $600,000 State Grant

Thursday, March 9, 2017 - NEWS RELEASE

San Diego – With the goal of making a smarter and cleaner San Diego for future generations, Mayor Kevin L. Faulconer was joined today by City Councilmember Lorie Zapf and community leaders to tout the successful installation of adaptive traffic signals in the Point Loma and Midway neighborhoods that have significantly improved traffic flow and reduced vehicle stops.

Through a $600,000 state grant, the City of San Diego installed 12 “Adaptive Traffic Systems” along the Rosecrans Street corridor from Hancock Street to Nimitz Boulevard as a quality-of-life improvement for neighborhood residents. These smart traffic signals communicate with each other and adjust signals, memorize traffic patterns, improve traffic flow and reduce vehicle stops.

“We’ve made a concerted effort over the past few years to improve neighborhoods by installing smart infrastructure along some of San Diego's most congested roadways,” Mayor Faulconer said. “Everybody hates sitting in traffic so we’re turning to new technology to solve this age-old problem. These smart signals adjust traffic lights to keep cars moving rather than sitting at stoplights.”

Since being installed last fall, the new traffic signals have reduced travel time by as much as 25 percent and decreased the number of vehicle stops by up to 53 percent during rush hour periods. For example, data from January shows the morning commute on southbound Rosecrans Street decreased from seven minutes to five minutes on average.

“The installation of these new adaptive traffic signals means less time spent on the road and more time for commuters to spend with their families,” Councilmember Zapf said. “Residents are catching more green lights than ever before and the community is thrilled about it.”

Nationally, only about 1 percent of traffic signals use this technology. The City has installed adaptive traffic signals along several heavily-trafficked roadways in recent years, including Friars Road, La Jolla Parkway, Lusk Boulevard, Mira Mesa Boulevard and Vista Sorrento Parkway.

The Mira Mesa project, which was installed last summer, won an award from Save California Streets.

The smart traffic signals along Rosecrans Street mark the largest installation in the City so far.

“We would like to thank Mayor Faulconer, Councilmember Zapf and City Staff for making this possible,” said Jon Linney, Chair of the Peninsula Community Planning Board.
