Future of Pedestrian Plazas Still Uncertain

Mayor Michael Bloomberg is not saying if the highly touted street closures in Times Square and Herald Square have fallen short of the city's expectations for improving traffic flow. But he is hinting that initial estimates of a 17 percent improvement have not materialized.

"It's never exactly the way you described it," he says. "Some things will be better than we hoped for. And some things will be worse."

A report in The New York Times cited sources who say the results of the street closure pilot have been "disappointing." The Department of Transportation has yet to make the results public.
