New York,NY,USA -The WSJ, by TED MANN -August 19, 2012: -- It was almost a year ago, but by definition, many motorists missed it: Aug. 28 was the easiest date in 2011 to drive through Manhattan. That Sunday, the city's yellow taxis sped through Manhattan's central business district at an average of 16.3 mph, according to the New York City Department of Transportation... The slowest date: Jan. 28, a Friday after the city had been crippled by a blizzard that dumped nearly two feet of snow over three days. The average groundspeed was 6.9 mph... The city's slowest and fastest traffic days and a trove of other data were measured by the Department of Transportation using Global Positioning System data from the city's fleet of more than 13,000 taxi cabs. The data is included in the department's Sustainable Streets Index, an annual report to be issued Monday that describes in rare detail how people move through the nation's most densely packed city... In a town where walkers often outpace crosstown buses, dealing with congested streets is a tie that binds the city. An average of about 778,000 vehicles converge each day in Manhattan's central business district, defined as all of the island south of 60th Street... The report provides an uncommon amount of empirical data, from the percentage of commuters who walk or take public transportation to work (65%) to how many fewer pedestrians were injured along East 180th Street after street improvements (67%)... And it sheds light on what many motorists consider something of a dark art: discerning when they can best dodge traffic...Labels: traffic congestion
