Within the past month, a new signal system was installed on White Bear Avenue at Margaret Street in St. Paul to make it easier and safer for bicyclists and pedestrians to cross the four-lane road.
It's called the HAWK system, short for high-intensity activated crosswalk. The system resembles a traffic light, but it's really a beacon attached to mast arms. The beacon head has two red lenses above a single yellow lens.
Unlike conventional traffic lights that give drivers a red, yellow or green light, the HAWK system remains dark until a bicyclist or pedestrian pushes a button to activate it. When the beacon is dark, motorists can proceed as normal. Once it is activated, drivers will see a single flashing yellow light, a warning that they should prepare to stop. When the beacon turns a solid red, drivers must stop. That is when pedestrians and bicyclists will see a "Walk" sign indicating that it should be safe to cross.
Motorists will see flashing red lights at the end of the cycle, which indicates that the time for pedestrians to cross is running out. When the beacon is in the flashing red mode, drivers can treat it like a stop sign, meaning they must come to a complete stop, look both ways, then proceed if the crosswalk is clear.
A few other HAWK systems are operating around the metro area in places such as Forest Lake, Coon Rapids and Dakota County, but they are at mid-block crossings. The one at Margaret Street is different in that it is at an intersection. Drivers are still getting used to it, said Jerry Auge, a construction engineer with Ramsey County Public Works.
"There is a bit of a learning curve going on," he said. "Pedestrians and bicyclists should not let down their guard and should make sure those cars are stopping.
"Motorists should be aware of their surroundings. The light is a warning to motorists for the potential that pedestrians or bicyclists might be present."
Of course, the signal systems only work when pedestrians use them properly and motorists obey them.
