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. The… Read More

Mobility and Accessibility Resilience of Transportation Infrastructures

David Yang
The objective is to address practical challenges related to mobility and accessibility following natural disasters. The anticipated outcome of this project will be to provide actionable insights and solutions that can be implemented in real-world transportation systems. By leveraging the available data from state DOTs and applying analytical techniques, our research will provide valuable insights and recommendations that can be readily implemented by transportation practitioners and… Read More
