Green-light priority-traffic technology possible solution for school-bus driver shortages

Across the United States, communities of all sizes and regions are facing school bus driver shortages. New research from Georgia shows promise in a technological solution to this widespread problem.

A pilot program conducted this spring at the Fulton County School System in Alpharetta, Ga. tested out devices that give vehicles the right of way at traffic signals. Two school buses, one diesel and the other powered by propane, were outfitted with onboard units that communicate via cellular network with 62 traffic signals along each route, turning the lights green on approach.

The program demonstrated “a clear and measurable reduction in route travel time for both school buses as a result of the decrease in total number of unscheduled stops and an increase in average speed of the bus along the route,” notes a report about the findings prepared by Kimley-Horn, a Boise-based consulting firm. “Less time on the road and fewer bus stops equates to direct safety and mobility benefits for the bus driver, students, parents, nearby motorists, and the (Fulton County School System). The pilot program enabled bus drivers to more frequently arrive at school on time and allow students to eat breakfast before going to class and starting their day.”

Specifically, vehicles equipped with the green light technology saw a 40 percent decrease in unscheduled stops, a 13 percent reduction overall in trip times, a 13 percent improvement in fuel economy and a 12 percent reduction in harmful emissions.
