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

E-bike Lending Libraries Synthesis

John MacArthur
Despite the practical and sustainable mobility benefits of e-bikes, personal ownership and maintenance are considered barriers to adoption (Fitch et al., 2022). Lending e-bikes may address some of the challenges of shared micromobility programs, such as ease of access and payment, but comprehensive evaluations to date have focused on specialized systems, including a research project loaning e-bikes in Norway (Fyhri et al., 2017), and another available only to Google employees (Fitch et al.,… Read More
