Research Highlights
E-bike Lending Libraries Synthesis
John MacArthur
Despite the practical and sustainable mobility benefits of e-bikes, personal ownership and maintenance are considered barriers to adoption (Fitch et al., 2022). Lending e-bikes may address some of the challenges of shared micromobility programs, such as ease of access and payment, but comprehensive evaluations to date have focused on specialized systems, including a research project loaning e-bikes in Norway (Fyhri et al., 2017), and another available only to Google employees (Fitch et al., 2...

Active Travel Behavior and Spatial-Temporal Land Use Mixing
Steven Gehrke
Urban policies have emphasized the importance of land use mixing as an intervention beholding of lasting planning and public health benefits. Transportation planners have identified potential in efficiency gains achieved by increasing land use mix and the subsequent shortening of trip lengths; whereas, public health research has accredited increased land use mixing as an effective policy for facilitating greater physical activity. However, despite the myriad benefits and extent of topical res...
