Bike-share services provide an affordable and environmentally sustainable transportation option. Research has shown that bike-share use can reduce car dependence and facilitate access to public transit. Expanding the use of these services can help cities meet environmental goals and, if done right, better serve transportation-disadvantaged residents. Researchers at the University of California, Davis surveyed households and bike-share users in the Sacramento region and used both behavioral modeling and market segmentation approaches to identify opportunities for increasing demand while improving access for low-income groups. The results can inform cities’ efforts to expand bike-share services.
