The present work deals with the dynamic rebalancing of bicycle-sharing systems. Truck-based and pricing-based regulation heuristics are designed and implemented. Their performance is assessed and compared using real instances of up to 30 stations from Washington bicycle-sharing system. The contribution of this study resides in the development of easy-to-implement yet effective and high-impact heuristics.
