New report: TNcs and congestion

In our new report, we ask the big question:
What impact do ride-hail companies like Uber and Lyft have on congestion in San Francisco?

We compared congestion between 2010 and 2016 using three metrics: vehicle hours of delay, vehicle miles traveled, and speed.

We found that ride-hail companies are responsible for about 50 percent of increased congestion on San Francisco streets. Job and population growth are responsible for most of the rest of our city's worsening congestion.

Repaving San Francisco streets with funding from Senate Bill 1

The Transportation Authority board recently dedicated $6 million in state funds to support critically-needed street repaving projects. This funding comes from Senate Bill 1, and will be matched with $6 million from San Francisco's half-cent sales tax for transportation.Project map

San Francisco Public works will use these funds, along with an additional $8.6 million from Senate Bill 1, for street improvements in neighborhoods spanning from the Sunset to Twin Peaks to Visitacion Valley. Improvements include repairs to the road base, paving work, curb ramp construction, and sidewalk upgrades. 

San Francisco Public Works maintains more than 900 miles of streets and roadways. Funding to maintain these roads comes from numerous sources, including the Road Repaving and Street Safety bond passed in 2011, the City’s half-cent sales tax for transportation, state funds such as California’s Senate Bill 1, and more.

Keeping our streets in a state of good repair saves the City millions of dollars in deferred maintenance and repair costs. See more information on San Francisco Public Works Street Resurfacing Program.


Funds from Regional Measure 3 could fund many transportation needs

Regional Measure 3 is a $4.45 billion traffic relief and transit improvement program funded by increased bridge tolls on the Bay Area's seven state-owned toll bridges (all toll-bridges except the Golden Gate Bridge). Residents in San Francisco and other Bay Area counties voted to approve this measure in the June 5, 2018 election.

What’s in it for San Francisco? The measure includes funding for many critical local and regional projects including:

  • Muni and BART fleet expansion
  • The Caltrain downtown rail extension
  • Expanded ferry service
  • Bay Trail and Safe Routes to School upgrades
  • Regional carpool or express lanes
  • Clipper upgrades and more.

These projects will be financed by a $1 increase in tolls on the Bay Area’s seven state-owned toll bridges beginning Jan. 1, 2019, followed by a $1 increase in January 2022 and another $1 increase in January 2025.

New Report: Emerging Mobility in San Francisco

Transit, a bike and people calling a ride on phones Many new technologies and services have appeared on San Francisco’s streets over the past few years, from ride-hail companies, to scooter sharing, to on-demand delivery services.

This month, we released a new report evaluating how these services line up with issues like equity, sustainability, and safety. One major take-away: We found that companies that share data and partner with the City on pilots are better at helping meet City goals.

The Neighborhood Transportation Improvement Program funds community-based neighborhood-scale planning efforts, especially in underserved neighborhoods and areas with vulnerable populations (e.g. seniors, children, and/or people with disabilities).

The program was developed in response to mobility and equity analysis findings from the San Francisco Transportation Plan, the city’s 30-year blueprint guiding transportation investment in San Francisco, and the Transportation Authority Board's desire for more focus on neighborhoods, especially on Communities of Concern and other underserved neighborhoods.

The transportation plan found that walking, biking and transit reliability initiatives are important ways to address socio-economic and geographic inequities.

The Neighborhood Transportation Improvement Program is made possible by the Transportation Authority through grants from San Francisco's half-cent sales tax for transportation.
