Introducing bike-share to a city correlates with an increase in light and heavy rail ridership, but a drop in bus ridership, according to a study from researchers at the University of Kentucky.
The study found a 1.8% decrease in bus ridership. In addition, heavy rail ridership experienced a decrease of 1.3% per year after ride-hailing services entered a market, while bus ridership saw a decrease of 1.7% per year. But the data found that bike-share had a positive effect on subway ridership, increasing it by 6.9%, and light rail ridership saw an uptick of 4.2%.
The study examined data from 2002-2018 in seven large U.S. cities: Boston, Chicago, Denver, Los Angeles, New York City, San Francisco and Washington, DC. It primarily relied on data from the National Transit Database as well as supplementary data from the U.S. Census Bureau’s American Community Survey.
