Vehicle Miles Traveled Data Portal

Learn about the Vehicle Miles Traveled Data Portal.

The Bay Area is home to more local climate action plans than any other metropolitan region in the U.S. To assist Bay Area local governments in developing and updating the community-wide greenhouse gas emissions inventories that are central to these planning efforts, the Air District has partnered with the Metropolitan Transportation Commission to create this Vehicle Miles Traveled Data Portal.

Jurisdictions in the Bay Area will find this site useful for developing and updating their greenhouse gas inventories, supporting climate planning activities, tracking progress, and understanding their community’s transportation emissions within the broader context of the region. The data provided in this portal is consistent with the travel outcomes associated with MTC’s long-range transportation plan.

The Air District and MTC hosted a walkthrough webinar on June 17, 2024, which helpfully explains how to use version 2.0 of the VMT Data Portal. Watch a recording of the VMT Data Portal Walkthrough Webinar.
