If you use a bike-share system, you likely rely on an app that gives you a real-time distribution of the bikes and empty docks in your area.

African Bus Routes Redrawn Using Cell-Phone Data | MIT Technology Review
Researchers at IBM, using movement data collected from millions of cell-phone users in Ivory Coast in West Africa, have developed a new model for optimizing an urban transportation system.
The IBM model prescribed changes in bus routes around the around Abidjan, the nation’s largest city. These changes—based on people’s movements as discerned from cell-phone records—could, in theory, slash travel times 10 percent.
