A new traffic control device will begin operating at the intersection of North Blair Street and East Mifflin Street on Thursday, according to the city of Madison.
The goal of the pedestrian and bicyclist hybrid beacon will be to make travel across a busy arterial street safer. In addition to safety, city officials said they also hope it encourages more people to skip using cars, cut down on pollution and relieve traffic congestion.
Madison's beacon will only be activated when a button is pushed. Motorists will on North Blair Street will see a flashing yellow light, followed by a steady yellow light. Officials said drivers should slow down and prepare to stop when the yellow light appears.
