Mobility hubs are major transit access points and an integrated part of multi-modal transportation planning efforts. For the implementation of bicycle infrastructure improvements around mobility hubs a better understanding of bicycle access distances is needed. Using responses from on-board travel surveys in three U.S. metropolitan areas, this study found that median bicycle access distances to transit stations are within the buffer radii suggested for community hubs (1 mile) and gateway hubs (2 miles) in long-range transportation plans. Multiple regression analysis identified several street and transit network characteristics affecting bicycle access distance, which should be considered when planning infrastructure improvements.
