Station-free bike sharing system (SFBSS) has received much attention recently. It provides an alternative mode of transportation for short-distance urban travel . Different from conventional station-based bike sharing systems, this new service allows users the flexibility to locate and unlock a bike nearby and park it at a site close to the destination. Because of its flexibility and convenience, the adoption and usage of SFBSS has increased significantly. However, the flexibility exacerbates the supply and demand imbalance issue due to the uneven supply/demand for the service across space and time. Accurate depiction and analysis of spatial and temporal imbalance are critical to understanding the SFBSS imbalance issue and improve the rebalance operation efficiency. Different from station-based bike sharing system, SFBSS has no fixed station and the associated station catchment area and station level bike inventory. As a result, system level imbalance needs to be re-defined. Using station-free bike trip-level data in Beijing, this study will define the SFBSS imbalance problem, identify the spatial-temporal variation of the supply and demand imbalances and analyze the influence factors. Our findings offer important insights into the efficiency improvement of station-free bike sharing and have the potential to contribute to sustainable transportation.
