Dog-bites-man: L.A. congestion still worst in North America

Travel times during peak hours take, on average, 33 percent longer than when traffic is flowing freely (you know, like Sundays at 6:30 a.m). That's according to something called the TomTom Congestion Index, which measure traffic for major cities. For a 30-munute L.A. commute, the extra time translates into a loss of 92 hours each year. By the way, the most congested day of the quarter was Feb. 17, and Thursday mornings and Friday evenings are busiest. Friday mornings and Monday evenings are the lightest. And yes, there are cities around the world that are in worse shape then L.A., among them Warsaw, Rome, and Brussels.
