As smart cities find ways to work with mobility operators, one of the questions that spring to mind is the relationship between infrastructure investments and mobility service ridership. Susan Xu used time series models to monitor the attribution of bike lane investments on Citi Bike ridership over time to provide decision support to NYC DOT. For example, each mile of bike lane investment in Manhattan in the period of study contributed to 285 more bikeshare trips. The research was funded by NSF CMMI-1634973.
