TNCs Today: A Profile of San Francisco Transportation Network Company Activity


Transportation Network Companies such as Uber and Lyft are an increasingly visible presence on San Francisco streets. But until now there has been no comprehensive data to help the public and policy-makers understand the volume, or frequency and coverage of TNC trips or their impact on San Francisco’s streets.

“TNCs Today: A Profile of San Francisco Transportation Network Company Activity,” provides the first comprehensive estimates of Uber and Lyft activity in the city.

Key findings of the report, which focused only on Transportation Network Company trips made entirely within San Francisco, include:

  • On a typical weekday, TNCs make more than 170,000 vehicle trips within San Francisco, approximately 12 times the number of taxi trips, representing 15% of all intra-San Francisco vehicle trips.
  • TNC trips are concentrated in the densest and most congested parts of San Francisco, including the downtown and northeastern core of the city. At peak periods, TNCs are estimated to comprise 20-26% of vehicle trips in Downtown areas and the South of Market. At the other end of the range, TNCs comprise 2%-4% of peak vehicle trips in the southern and western part of the city.
  • On an average weekday, more than 5,700 TNC vehicles operate on San Francisco streets during the peak period. On Fridays, over 6,500 TNC vehicles are on the street at the peak.
  • TNCs drive approximately 570,000 vehicle miles within San Francisco on a typical weekday. This accounts for 20% of all local daily vehicle miles traveled (VMT) and includes both in-service and out-of-service mileage. Taken over total weekday VMT, which includes regional trips, local TNC trips account for an estimated 6.5% of total weekday vehicle miles traveled.
  • TNCs provide broader geographic coverage than taxis, though there appear to be lower levels of both types of trips in the south and southeast part of the city.

Subsequent reports will address important analytic and policy questions regarding TNC activity in San Francisco. These future studies will assess TNC policies, best practices, and a range of topics that reflect citywide goals including: safety, transit ridership and performance, congestion and air quality, disabled access and equity, and land use and curb management.
