Mobile application prototype for public transportation trip planning
Paper presents a prototype of a system that allows passengers of public transportation to plan their trips. It is assumed that the user enters information concerning the planned trip (start address, end address and start time) and the system provides (i) description of the most convenient route i.e. one with the minimum number of transfers, the shortest walking distance and possibly the shortest trip time and (ii) a map presenting the route. The system is delivered to the end-user as a mobile application. Mobile devices (cellular phones, smartphones) are oftentimes equipped with a GPS (Global Positioning System) unit. The client's application makes use of the GPS unit so that the users who do not know their exact location can conveniently plan their trips. The system is built up of four programs implemented in Java. Oracle Spatial is used to store, access and analyze spatial data in the system.
