An article in Transportation Research examines the role of amenities such as bicycle parking, cyclist showers, free car parking, and transit benefits as determinants of cycling to work. The analysis is based on commute data of workers in the Washington, DC area. Results of rare events logistic regressions indicate that bicycle parking and cyclist showers are related to higher levels of bicycle commuting, even when controlling for other variables. Also, the odds for cycling to work are much higher for employees with access to both cyclist showers and bike parking at work compared to those with just bike parking, but no showers.

Employer provided transit commuter benefits appear to be unrelated to bike commuting, however free car parking at work correlates to a 70 percent reduction in the odds for employee bike commuting.
