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

Understanding Human-centered AI through Data Integration and Analytics

David Yang
Human Centered Artificial Intelligence (HCAI) is an approach to developing and implementing Artificial Intelligence technology applications that focuses on the needs of individuals and communities who utilize these applications. This project intends to develop course modules and tools for students to understand human-centered AI methods and data requirements, conduct specific mobility analysis using AI-empowered technologies, and build multimodal technology solutions to improve mobility. The… Read More
