Bogard launched its traffic initiative — fi"*ll on Wheels — asking readers to share their gridlock grind. We promised to get answers to the problems they identified. Up first is the most ccnlznon complaint we heard: scores of traf- fic signals that drivers thick are out of sync, making their already - difficult daily commute harden "The massive jobof keeping all traffic lights Weir ' on OUR OPINION: Miami-Dade's traffic light guru, Frank Aira, gives us a primer He told the Board that his wish for a liveable traffic flow is this: would be that every day, ami-Dade traffic would be like that first day after the last school lets out for summer vacation, when everyone marvels at how great the traffic flow was that day," he said.
