Evaluating and Enhancing Public Transit Systems for Operational Efficiency, Service Quality and Access Equity

Ran Wei
Liming Wang , Aaron Golub , Thomas Cova
Regular assessment and improvement of the performance of public transit systems are essential for transit service providers given limited funding and growing public needs. Performance evaluation can help transit agencies identify underperforming services, plan for potential investments, justify investments, and communicate accomplishments and challenges. However, the evaluation of transit system performance is complex and challenging due to the diverse and competing goals of a public transpor... Read More

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...
