Research Highlights
Automated Detection, Tracking, and Safety Analysis of Pedestrians and Cyclists Using YOLOv9
Banafsheh Rekabdar
Sirisha Kothuri , Nathan McNeil
This applied research project aims to adapt and further train YOLOv9 to enhance its ability to accurately detect, track, and count cyclists and pedestrians in video data from the Portland Metro Area. The method will also extract surrogate safety metrics, such as Post Encroachment Time, which are crucial for assessing conflicts and designing safer, more efficient transportation facilities. By analyzing these interactions during daylight, the project seeks to deepen our understanding of active ...

Understanding Economic and Business Impacts of Street Improvements for Bicycle and Pedestrian Mobility - A Multi-City Multi-Approach Exploration [Phase 2]
Jenny Liu
This research project explores the economic impacts of bicycle and pedestrian street improvements in the United States using multiple data sources and analytical approaches. Building on studies in New York City and San Francisco, researchers examined before-and-after data for street improvements on 14 corridors in six cities: Indianapolis, Memphis, Minneapolis, Portland (OR), San Francisco, and Seattle.
WHY DO THIS STUDY
To make cities more livable and in response to growing concerns over...
