Most major cities have implemented some level of bike sharing programs in their community. And based on usage reports, these programs have shown to be well received by people in these communities. The idea behind the setup is fairly simple: install bike docking stations at key locations through a city and allow people to rent the bikes using self-pay kiosks. Users pick up the bikes from one station and deliver them to another near their destination. The result is a convenient and relatively low-cost transportation alternative that does not add to existing congestion levels.
Setting up the program can be easier than planning and constructing more traditional infrastructure. They key is to determine station locations and number of docks/bikes per station depending on expected demand. Choosing a location where there is already room for a station such as along an existing sidewalk can also cut costs and installation times. For an optimum layout, it’s also a good idea to plan stations in a manner similar to transit station layouts with a type of grid system that allows for pedestrian trips less than 10 to 15 minutes. All of this is probably fairly obvious to transportation professionals. But as with most public works services, the critical, and sometimes unforseen, component is in the operations. In bike sharing, the success of the service relies on the ability to manage the number of bikes at each station.
The service level for users diminishes when no bikes are available to meet demands. And this is also true when users cannot find spaces to return bikes at stations near their destinations. This operational challenge has been studied in several papers. One more recently released paper, Dynamic vehicle redistribution and online price incentives in shared mobility systems indicates the main costs of operations, which have been reported at $1,200 to $1,944 per bike annually, are also dependent on this need to balance the number of bikes between stations. Following is an excerpt from the report:
“One of the major contributors to operational costs is the need to operate staﬀed trucks for manual relocation of bicycles, in order to balance the diﬀerence between supply and demand at various stations. If this eﬀort were not made, the arrival and departure of customers would cause many stations to run full or empty, and the customer service rate would drop below acceptable levels.”
So to run well throughout the day, the program relies on an operator and staff to constantly monitor the number of bikes at each station and pick up and deliver bikes as needed between them.

And to cut costs, some studies have suggested offering incentives to riders for delivering bikes where they are most needed. This would seem simple to implement because many stations and systems are digitally monitored. So users can easily determine the number of bikes at a station using apps such as CycleFinder. Incentives could be offered once a station hits a certain level and then trigger the app to display an icon through these programs alerting users to the incentive. Some studies have suggested that incentives could eliminate the need to manually balance bikes on the weekend. However, during the week when there is heavy commuter use, manual balancing would still need to take place.
