Research Highlights
Washington State Pedestrian and Bicycle Miles Traveled Project
Krista Nordback
Estimates of vehicle miles traveled (VMT) drive policy and planning decisions for surface transportation. No similar metric is computed for cycling and walking. What approaches could be used to compute such a metric on the state level? This report discusses three such approaches, identifies the advantages and disadvantages of each, and applies them to Washington State. The first approach employs travel survey data. The second approach is sample-based using pedestrian and bicycle count data. T...

Communicating Research through Comics: Transportation and Land Development
Kelly Clifton

This project created a transportation comic, "Moving From Cars To People," which offers a succinct and fun introduction to a complicated topic: namely, how the built environment in the United States came to be designed for cars and what we can do about it.
The comic includes a dialogue, taking place in various urban settings, between characters Kelly and Kristi who are based on the two principal investigators, Kelly Clifton and Kristina Currans. The two have a long history of collaboration...
