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...

Human Centricity through AI - Innovating Public Engagement for Transportation Projects with Large Language Models
Antonie Jetter
Ameeta Agrawal
Researchers created a qualitative dataset of public planning documents, community comments, forum conversations, newspaper articles, etc., about the SW Corridor Lightrail project in Portland, OR. The team will use this dataset to set up a series of experiments enabled by the ChatGPT4 LLM from Open.AI. This will provide preliminary insights into the potential of LLMs as data interpretation aids.
