Bikeshare Trip Generation in New York City
Cities around the world and in the US are implementing bikesharing systems, which allow users to access shared bicycles for short trips, typically in the urban core. Yet few scholars have examined the determinants of bikeshare station usage using a fine grained approach. The authors estimate a series of Bayesian regression models of trip generation at stations, examining the effects bicycle infrastructure, population and employment, land use mix, and transit access separately by season of the year, weekday/weekend, and user type (subscriber versus casual) The authors find that bikeshare stations located near busy subway stations and bicycle infrastructure see greater utilization, and that greater population and employment generally predict greater usage. The authors' findings are more nuanced, however; for instance, those areas with more residential population are associated with more trips by subscribers and on both weekdays and non working days; however, the effect is much stronger on non working days. Additional nuances can be found in how various land use variables affect bikeshare usage. The authors discuss these nuances in detail and elaborate on how these findings may be of use to transportation planners.
