Jean Buckley pulled up to the intersection of 42nd Street and Hiawatha Avenue S. in Minneapolis on a recent Sunday morning, and the light instantly turned green.
"Amazing," said the resident of south Minneapolis' Longfellow neighborhood, who in the past often waited several minutes to get the go signal. "I got to church for the first time in years to hear the choir sing our opening hymn."
Buckley and other drivers are now spending half as much time at red lights on Hiawatha and its cross streets since a new traffic control system was installed last fall at intersections between 26th and 50th Streets, Minneapolis officials said Wednesday.
A new $1.1 million system with 160 loop detectors replaced old units that often skipped phases for two and three cycles when light-rail trains passed by, leaving motorists trying to cross or make a turn left on or off Hiawatha waiting as long as 10 to 12 minutes for a green light.
In the four months since the system went live, the number of drivers waiting more than two minutes for a green light is down 50 percent, and the maximum wait time has dropped from 11 minutes to four, said Council Member Sandra Colvin Roy, who represents an area of south Minneapolis and is chairwoman of the Transportation and Public Works Committee.
Punching the clock
Roy cited electronic data collected from the system and manual observations by people with stopwatches.
"We have significantly reduced the wait times for drivers in this corridor," she said. "And if we could measure the blood pressure of those who live in the neighborhood, I'm sure that has gone down, too."
