The document describes a 2011 project for an on-demand transportation service. It outlines the system structure connecting passengers and drivers through a central server. The server uses various technologies like Ruby, databases, APIs and cloud computing to receive user info, match riders and drivers, provide navigation assistance, and automate the system. Most of the Android app is complete along with matching, navigation and messaging features. Remaining tasks include developing iOS and tablet versions, improving the user interface, and enhancing the overall service.
