Plan To Coordinate Atlanta's Metro Traffic Lights

"Perdue chose a Georgia Regional Transportation Authority meeting to unveil a plan to repair and retime traffic lights to get traffic moving across the region...Similar efforts locally and elsewhere have produced measurable results. A 12,000-signal coordination in California sped up average travel times by 7 percent and reduced delays by 16 percent, according to Roger Henze, senior project manager for the authority. Closer to home, coordination of 178 lights in Gwinnett County sped up travel 22 percent and reduced delays by 36 percent."
