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… Read More

Using Maps and Online Tools to Operationalize Equity in Shared Mobility Services

Amanda Howell Anne Brown
This project translates research into practice through developing two practitioner-ready tools using findings from NITC project #1401 “Mobility for the People: Evaluating Equity Requirements in Shared Mobility Programs”. In “Mobility for the People,” we confirmed our hypotheses that while many US cities implement shared mobility program equity requirements, specific requirements range dramatically. In addition, many requirements are not supported by data collection efforts and evaluation… Read More
