Do city voters want to boot Mayor Michael Bloomberg's traffic fee plan off the island? If you ask Quinnipiac University, they do. If you ask Transportation Alternatives, they say Quinnipiac is biased.Though 89 percent of New Yorkers polled by Quinnipiac considered traffic congestion a "very serious" or "somewhat serious" problem, 57 percent said they opposed congestion pricing, according to a poll released yesterday.That number has grown since a July survey, when 52 percent opposed the plan.Manhattan was the only borough where a majority (54 percent) welcomed the plan. The highest opposition was in the Bronx, with 74 percent against it. The other boroughs had strong majorities in opposition as well.The federal government's offer of $354 million in transit funding if congestion pricing is approved wasn't viewed glowingly: 51 percent considered this "federal meddling in a municipal decision.""'Don't tread on me' ought to be the message on the city flag," said Maurice Carroll, director of the Quinnipiac University Polling Institute, in a statement.The poll, however, found 57 percent of voters would support the plan if the money is used to prevent an increase in mass transit fares and bridge and tunnel tolls.Bloomberg spokesman John Gallagher approved of that finding. "As in results from every other recent poll we've seen, if you tell people you're going to use the money to fund improvements and possibly prevent future fare increases, this poll shows that a clear majority support congestion pricing," he said.According to Transportation Alternatives, a nonprofit advocacy group for bicyclists and pedestrians, the plan will have limited impact on the 95 percent of New Yorkers who rely on public transportation.Paul Steely White, the group's executive director, thought the questions had "loaded language," such as the "federal meddling question," and criticized the poll for not specifying times that vehicles would be charged driving south of 86th Street."Knowledge of the details of congestion pricing is still limited among New York voters," he said in a statement, "so posing a question that suggests congestion pricing fees will apply at all times, rather than just from 6 a.m. to 6 p.m. on weekdays, is misleading and skews the results."
