ABSTRACT
The article focuses on the benefits of a wireless technology called traffic signal preemption in North America. Calgary Transit's buses in Calgary, Alberta are equipped with transmitters which switch a red light to green on command. Ninety-eight U.S. metropolitan areas have installed it in more than 30,000 intersections, or one-fifth of all intersections with traffic lights in the U.S. The Opticom unit of 3M manufactures the transmitters.
