SAN FRANCISCO, CA—The San Francisco Business Times has named Tilly Chang, Executive Director of the San Francisco County Transportation Authority, one of the Bay Area’s Most Influential Women for 2015.

The recognition comes as Ms. Chang oversees the Transportation Authority’s $700 million half-cent sales tax investment program which provides funding for major capital projects like the Doyle Drive rebuild, Muni Central Subway extension and Caltrain electrification and extension to the Transbay Transit Center. The agency also funds neighborhood-level transit and street infrastructure improvements across San Francisco.

“I congratulate Tilly Chang on this well-deserved recognition,” said Transportation Authority Chair Scott Wiener. “Tilly’s knowledge of the city, expertise in transportation planning and funding issues, and collaborative spirit are tremendous assets to the Transportation Authority.”

“It is an honor to be included among this diverse group of dynamic women in our region,” said Ms. Chang. “I am privileged to work with colleagues at the Transportation Authority and with our many partners to make a positive impact on San Francisco’s communities and our region.”

The Transportation Authority plans, funds and delivers transportation projects across San Francisco’s multi-operator, multi-modal network. Led by the Board of Supervisors, the agency is developing San Francisco’s streets, highways and transit systems to increase access, promote safety and advance the livability of the city.

Ms. Chang was named Executive Director of the Transportation Authority in 2013. Before that, she led planning initiatives for the agency including bus rapid transit projects, neighborhood studies, and San Francisco’s first long-range transportation plan. The agency’s current efforts include coordinating BART, Caltrain and Muni capacity improvements, developing carpool lanes on regional freeways, and advocating for new transportation revenues at the local, state and federal levels.

Ms. Chang serves on the Association of Bay Area Government’s Regional Planning Committee and advises SPUR and the UC Transportation Centers research program. Prior to joining the Transportation Authority, she worked at the World Bank, the Metropolitan Transportation Commission and in the private sector. She holds degrees in Transportation, Economics and City Planning from M.I.T. and U.C. Berkeley.
