Research Highlights

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...

Data-Driven Mobility Strategies for Multimodal Transportation

Yao-Jan Wu
Xianfeng (Terry) Yang , Sirisha Kothuri
How can we use a variety of data-driven speed management strategies to make transportation safer and more efficient for all modes–whether you’re driving, walking or taking transit? The project was led by Yao Jan Wu, director of the Smart Transportation Lab at the University of Arizona. Co-investigators were Xianfeng Terry Yang of the University of Utah, who researches traffic operations and modeling along with connected automated vehicles, and Sirisha Kothuri of Portland State University, ...
