Problem
Walking and biking are two modes of travel that have rapidly gained in popularity in New York City (NYC)—in fact, NYC has seen bicycling activity quadruple over the last decade. Contributing to this rise is the “Citi Bike” program, NYC’s bikeshare system, which accounted for nearly 14 million bicycle trips in 2016. However, non-motorized transportation modes are not without risk. In 2013, the city experienced 178 pedestrian fatalities and 134 bicyclist fatalities. The following year, NYC adopted Vision Zero.
