Automated Detection, Tracking, and Safety Analysis of Pedestrians and Cyclists Using YOLOv9

Principal Investigator: Banafsheh Rekabdar

Co-Investigators: 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 metr ... Read More

Improving Accuracy and Precision of Pedestrian Volume Estimates Using Advanced Machine Learning Approaches

Principal Investigator: Sirisha Kothuri

Co-Investigator: Banafsheh Rekabdar

Counts provide the foundation for measuring nonmotorized travel along a link or a network and are also useful for monitoring trends, planning new infrastructure, and for conducting safety, health, and economic analyses. Most agencies still use manual ... Read More

Exploring Bike Bus Programs in the United States

Principal Investigator: John MacArthur

Co-Investigator: Nathan McNeil

Photo by Jonathan Maus, BikePortland The trip to and from school is made by nearly every child in Oregon every school day. Bike and walk buses, or organized groups of school children, parents, and ride/walk leaders, seek to encourage biking and wa ... Read More
