SCAG Releases ‘Transportation Trends Report’ to Assess the State of Southern California Mobility

The latest publication of SCAG’s “Transportation Trends Report,” a bi-annual assessment of transit ridership statistics, roadway performance measures, and commuting patterns, is now available online. 

In the report, which reviews data through June 2025, SCAG analyzes 27 transit agencies based on their operational scale and the availability of consistent and comparable ridership data. The SCAG region has a diverse and expansive mobility ecosystem, with over 100 public transit operators providing a broad range of services across six counties. These services span local fixed-route bus systems, regional transit networks, intercity services, and commuter rail—reflecting the region’s varied geography and population density—as well as a cross-section of public operators, including municipal systems, joint powers authorities, county transportation commissions, and transit districts. The “Transportation Trends Report” evaluates transportation trends and ridership across the SCAG region by mode and month to provide a systemwide assessment.  

As of June 2025, transit ridership and vehicle miles traveled in the SCAG region have continued to recover from the impacts of the COVID-19 pandemic, though patterns vary by mode. Across all transit modes, bus ridership has led the recovery, followed by light and heavy rail, while commuter rail has been the slowest to return to pre-pandemic ridership levels. For automobile traffic, overall vehicle miles traveled (VMT) is at 97 percent of pre-pandemic levels. Remote work continues to be a key factor in travel trends; approximately 34 percent of workdays were performed from home over the last year, contributing to reduced peak-hour demand across all travel modes.
