The mobile terminal (user terminal) includes a communication module (communication unit) that communicates with a server (first server) that manages electronic payment of transportation fares, and a display (display unit). The display displays information on excess charges for using transportation outside the valid range of the ticket. The communication module transmits information regarding payment of excess charges to the server when the user uses transportation outside the valid range.

Systems and methods for planning a public transit system including determining costs of providing a fixed-route service are provided. The systems and method can receive a set of fixed route lines and trips for the public transit system and a plurality of ride requests. The systems and method can include determining a plurality of possible proposals for each ride request of the plurality of ride requests based on the received set of fixed route lines and trips and/or one or more constraints, determine for each ride request a set of proposals of the plurality of proposals having the lowest overall cost to provide the fixed-route service and determine whether one or more of a subset of the fixed route lines or trips are to be removed from the received set of fixed route lines and trips.
