Faster red light waits thanks to cutting-edge tech in Oakland.

TLDR:

• University of Michigan researchers partnered with the Road Commission for Oakland County to update traffic signal timing using GPS data from General Motors vehicles.
• Reprogramming traffic lights based on real-time traffic patterns led to a 20% to 30% decrease in the number of stops, making the system more efficient and safer.

University of Michigan researchers collaborated with the Road Commission for Oakland County to conduct a pilot study in Birmingham aimed at reducing red light wait times through cutting-edge technology. The study, which lasted 18 months and collected data from 34 intersections, utilized GPS data from General Motors vehicles to update traffic signal timing more frequently and cost-effectively. By reprogramming traffic lights based on real-time traffic patterns, researchers were able to decrease the number of stops by 20% to 30%, making the system more efficient and safer for drivers. This innovative approach eliminates the need for manual car counts every five to 10 years, saving time and resources for the county road commission. Craig Bryson, senior communications manager for the road commission, expressed excitement over the potential global impact of this study and its ability to revolutionize traffic signal timing worldwide.
