PI: Yao-Jan Wu, Ph.D., P.E.
Co-PI: Bharat Pathivada, Ph.D.
PM: Blake Olofson
Sponsor: City of Tucson
July 2025 - July 2026

The goal of this multi-phase project is to optimize traffic signals in the City of Tucson to improve mobility, safety, and efficiency. Multi-source data was automatically collected or estimated city wide, and a website (Tucson.UA-Star.org) was developed to implement and analyze the big traffic data. The data is used to provide support for signal re-timing and safety studies.
