Board approves 2025 Congestion Management Program amid questions on data and neighborhood coverage
Summary
The Transportation Authority adopted the 2025 Congestion Management Program, which reports trends in speeds, vehicle miles traveled, transit ridership and collisions; commissioners pressed staff on data comparability, neighborhood‑level causes of congestion and requests to add corridors to the CMP network.
The San Francisco County Transportation Authority on Dec. 9 adopted the 2025 Congestion Management Program, a biennial report that tracks multimodal performance measures across the city.
Chen Ho Chao, transportation modeler, presented key findings: arterial and freeway speeds decreased by about 5% between 2024 and 2025, arterial vehicle counts have recovered to roughly 92% of pre‑COVID levels, vehicle miles traveled are about 10% below pre‑COVID figures, transit ridership is recovering but remains lower than before the pandemic, and fatal collisions have trended up since 2017 with 42 fatalities in 2024. Chao also noted that shared bike and scooter monthly trips rose sharply in 2025.
Commissioners asked technical questions about a vendor data product change that creates a disconnect in trend lines (staff said the vendor change occurred in 2017 and cautioned about direct year‑to‑year comparisons), requested neighborhood‑level analysis to better understand proximate causes of congestion, and asked about adding specific corridors to the CMP monitoring network. Staff said additions beyond the adopted network are possible but that changing the official network would require board action to preserve longitudinal comparability.
One public commenter, Heather Davies (District 4), raised concerns about project‑related traffic diversions and cumulative construction impacts in the Sunset and other corridors.
The board moved and approved the 2025 CMP (moved by Commissioner Cheryl; seconded by Commissioner Walton). Staff said they will continue monthly updates on the online San Francisco congestion dashboard and pursue biennial and targeted analyses requested by commissioners.
