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 ...

Sirisha Kothuri , Nathan McNeil
Portland State University is a subcontractor on NCHRP 17-87 award to Kittelson & Associates, Inc: http://apps.trb.org/cmsfeed/TRBNetProjectDisplay.asp?ProjectID=4373
Challenge
Despite its prevalence as a transportation mode, walking receives less attention than the motor vehicle mode in terms of national guidance and methods to support planning, designing, and operating safe, functional, and comfortable facilities.
Solution
Kittelson partnered with Portland State University and the Hi...
