(Lauren Evans) Despite all the fist-shaking and agitated sighing over Bloomberg's expansion of the city's bike lanes and pedestrian plazas, a study from the DOT shows that contrary to widely-held belief, traffic has actually sped up over the past few years.

The 2012 Sustainable Streets Index offers information compiled using taxi GPS data, which the DOT began collecting for traffic studies in 2007. According to the Index, average taxi speeds in Manhattan's central business district increased from 8.9 mph in 2011 to 9.3 mph in 2012, and nearly 7 percent since 2008.

Other interesting statistics from the study include:

  • There has been a 58 percent increase in year round cycling since 2008
  • Since 2003, there has been an 11.3 percent increase of transit ridership to Manhattan's central business district, and a 6.5 percent decrease in vehicular traffic.
  • There has been a 9.5 percent increase in citywide transit ridership since 2003.
  • Bus ridership outside Manhattan's central business district decreased by 3.6 percent in 2011.
