Information distribution system, method, and program

Information distribution systems, methods, and/or programs register a point which meets predetermined registration conditions as a register point; select a predetermined register point as a predicted arrival display point; calculate a predicted arrival time at the predicted arrival display point; and display the predicted arrival on a map screen. Systems, methods, and/or programs obtain map data and traffic congestion information, including a plurality of congestion areas; set a priority for each congestion area; and display congestion detail information for a congestion area on the map screen based on the set priority. Systems, methods, and/or programs determine a priority for a register point; and display the register point on the map screen when the priority of the register point is greater than a predetermined value.
