Abstract:This work investigates the opportunities and environmental impacts brought about Electric bicycles (E-bikes) sharing program. Electric bicycles (E-bikes) are an emerging transportation technology with the potential of replacing other available modes. In this work, we investigate the ability of E-bike sharing to compete with different modes of transportation and the resulting use phase environmental impacts. An empirical approach is taken to build mode choice models informed through a survey study in Madison, Wisconsin. The resulting model reveals potential users of this technology and the underlying modal shifts triggered by its usage. A life cycle analysis (LCA) based on Well-to-Wheel (WTW) model is then adopted to quantify the use-phase environmental impacts of E-bikes. The analysis reveals the attractiveness of E-bikes as a mode of transportation, ultimately replacing other available modes. This directly translates into environmental impacts across five studied categories: energy consumption, greenhouse gas emission, particulate matter, sulfate and nitrate emissions. The electricity generation scheme is further analyzed to showcase the dependency between environmental benefits of E-bikes and the energy infrastructure used. Additionally, we look at how the E-bikes sharing program performed in comparison to other available modes during the pandemic.
