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.

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.
