Live V2X Transit Signal Priority Demo at UMTRI 60th Anniversary Symposium
Published:
Our CART Lab at Purdue University was invited to the University of Michigan Transportation Research Institute (UMTRI) 60th Anniversary Symposium (Oct 2-3, 2025, Ann Arbor, MI), where I gave a live demonstration of a Transit Signal Priority (TSP) system enabled by Vehicle-to-Everything (V2X) communication.
The Demo
A transit bus equipped with V2X on-board units drove through Mcity, showcasing how TSP leverages V2X communication to enable smarter, more adaptive traffic signals and to improve mobility and efficiency for priority vehicles in real-world traffic.
Real-World Deployment
The same system has served Route 6 transit buses along the Ellsworth corridor in southern Ann Arbor since August 2025. It was developed in the USDOT FHWA project Smart Intersections: Paving the Way for a National CAV Deployment; more on the system on the MMITSS project page.
