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...

How Can E-bike Purchase Incentives Grow the E-bike Market?
John MacArthur
Christopher Cherry , Luke Jones
The electric bicycle (e-bike) is a low-emission mode of transportation that offers communities benefits in the areas of health, planning, time, cost, street safety, congestion, air pollution, noise pollution, and energy security, among others. Despite the establishment of a stable and growing market, e-bike ownership remains prohibitively expensive for many people. Across the world, incentive programs have emerged as a popular technique in the effort to bridge the chasm of e-bikes' technology...
