About Zephyr

The Zephyr Foundation’s mission is to advance 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 these improved methods and tools to support decision-making that is inclusive and promotes equitable outcomes, shared prosperity, and sustainability.
