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...

Evaluating the Distributional Effects of Regional Transportation Plans and Projects
Kristine Williams
Aaron Golub
Metropolitan planning organizations (MPOs) have long been required to consider the equity implications of their regional transportation plans and processes. Funded by the National Institute for Transportation and Communities, this research aims to provide additional guidance to MPOs on how to evaluate distributional equity in regional plans and projects. The report begins with an overview of federal requirements related to equity in transportation planning. We then synthesize contemporary met...
