SYSTEM AND PROGRAM FOR GUIDING PEOPLE HAVING DIFFICULTY RETURNING HOME

摘要

PROBLEM TO BE SOLVED: To provide a system capable for guiding people who cannot return home by public transportation because of the failure to catch the last train or other reasons with the cost effectiveness of traveling and sleeping taken into account.;SOLUTION: A system for guiding people 1 having difficulty returning home, which includes a route presentation part 15, is designed to have a route DB 11, a cost DB 12, an accommodation DB 13, and a value DB 14 for storing economic value gained from traveling and sleeping searchable. The route presentation part 15, which searches the accommodation DB, the route DB, and the value DB, calculates sleeping time gained from each possible route from a first point as a departure point to a second point as a destination, calculates economic value gained from sleeping in a hotel and at home respectively on the basis of the sleeping time, and sums up the economic value from both as the total economic value. Searching the cost DB, the route presentation part 15 sums up costs needed for traveling and sleeping in a hotel as the total costs on a possible route basis and extracts one or more routes by which the difference calculated by subtracting the total costs from the total economic value is the greatest.;COPYRIGHT: (C)2015,JPO&INPIT
