A new report from the Institute of Transportation Studies at the University of California - Berkeley utilizes a case study approach of Bay Area Rapid Transit (BART) rail stations to examine factors that may have contributed both to increases in the number of bicycle trips to access rail stations and also to the enlargement of bike access‐sheds over time.  The authors document on‐site factors, such as an increase in the number of protected and convenient bicycle parking racks, as well as off‐site factors, such as increases in nearby bikeway facilities, to help explain the growing use of bicycles for accessing rail stations.  The adage “build it and they will come,” the study argues, holds for bicycle improvements as much as other forms of urban transportation infrastructure.  Pro‐active partnerships between various entities, including transit agencies, local government, transportation agencies, and bicycle advocacy organizations, are critical to ensuring such improvements are made.
