<p>PROBLEM TO BE SOLVED: To provide a service system notifying a time to start toward a nearest station from a current position in order to get on a railway at the optimum time. SOLUTION: A positioning system 2 specifies the position P of a portable terminal 1. A start information specification system 4 specifies the nearest station, a walking moving route from the position P to the nearest station, a railway route up to a destination station, a getting-on time at the nearest station for arriving on the destination station at a target time and a start time from the position P for arriving on the nearest station at the getting-on time. The renewal of information is performed by cyclically repeating the specification of the position P and tracking the movement of a portable terminal, and a user successively judges the time to start from the position P. A start information notification system 7 transmits the above information to the portable terminal 1 at the start time. The user knows the whole information of necessary route and time, and since their information is notified to the user at a time point when the user starts, the user is prevented from putting many hours in business and amusement.</p> |
