Research Highlights

Trip and Parking Generation at Transit-Oriented Developments

Reid Ewing
The decision of how best to allocate land around transit stations is a debated topic, with transit officials often opting for park-and-ride lots over active uses such as multifamily housing, office, and retail organized into transit-oriented developments (TODs). In practice, guidelines for providing parking and mitigating vehicle trips come mainly from the Institute of Transportation Engineers (ITE) Trip Generation Manual and the ITE Parking Generation Manual. However, both manuals have well… Read More

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
