Research Highlights

Measuring the Impacts of Social Media on Advancing Public Transit

Jenny Liu
(Jeff) Xuegang Ban
This project is a collaboration between Portland State University (PSU) and the Center for Infrastructure Transportation & Environment (CITE) at Rensselaer Polytechnic Institute seeking to develop performance measures for assessing the impacts of social media on promoting public transit. Revolutionary changes have occurred in the communication landscape, and there has been a rapid diffusion of social media use as a means of communicating transit information to the public.

Low-Cost Camera Sensors and YOLO-Based Computer Vision for Scalable Multimodal Traffic Monitoring

Banafsheh Rekabdar
Sirisha Kothuri , Nathan McNeil
This project provides the first systematic, multi-site validation of low-cost community-deployable edge-AI camera sensors integrated with YOLO-based computer vision for pedestrian and vehicle counting in real-world transportation settings. Building on the team's ongoing PacTrans-funded work on automated detection, tracking, counting, and safety analysis of pedestrians and cyclists, this project extends that foundation in two important directions: expanding the YOLO-based pipeline to includ...
