Zephyr Foundation

a 501(c)3 non-profit

Zephyr’s mission: advancing rigorous transportation and land use decision-making for the public good by advocating for and supporting improved travel analysis, and facilitating its implementation.


Our vision is to become the primary venue through which leading researchers and practitioners seek to develop and implement travel analysis methods and tools that are demonstrably more valuable, credible, transparent, tractable, reproducible, and usable.

We strive for those methods and tools to support decision-making that is inclusive and promotes equitable outcomes, shared prosperity, and sustainability.

Zephyr Board Election Results 2020

Congratulations and welcome aboard to our two newest Board members, Jeff Newman and Leta Huntsinger! Jeff and Leta were the highest vote-getters in the recently closed election by Zephyr members. Zephyr will benefit greatly from Leta's and Jeff's extensive involvement in our field and the experience they have gained in their past and current leadership roles at public, private, research and educational institutions. Welcome!

This also means two Board members have completed their terms, Billy Charlton and Leah Silen. Both Billy and Leah were founding Board members, involved with Zephyr since its inception. Thank you both for your service!

The new Board will soon convene to elect its officers and set an agenda for the coming year.
