Description
Description | A traffic signal system developed by University of Michigan researchers has reduced needless stops at intersections by up to 30% in Oakland County. The system uses GPS data from as few as 5% of vehicles to adjust signal timing in real-time. Initial implementation began in Birmingham, Michigan in 2022, with upgrades to 13 signals along Eight Mile Road in Farmington Hills and Twelve Mile Road in Royal Oak, and plans to fit 27 more intersections throughout the county. The project is a collaboration between the Road Commission for Oakland County and the research team, funded initially by a $1.45 million grant from the U.S. Department of Transportation for development and rollout at 40 intersections. The team is seeking further funding for broader implementation through the startup Connected Traffic Intelligence. |
