According to a recent report by Hunter UAP Professor William Milczarski and Professor Peter Tuckel (Sociology), New Yorkers on bikes are riding safer than they were 4 years ago. They are also proportionally more female.
The study, “Bike Lanes + Bike Share = Bike Safety” looked at the behavior of 4,316 bicyclists at 98 different locations in central and lower Manhattan. The researchers compared the resulting data to what they found in a similar, although not identical, survey in 2009. You can read the full report here.
