In this paper, we describe the design concept of the traveler support system, which can automatically rearrange the itinerary in correspondence with the change of an activity schedule. We also make an account of the result of the experimental operation of the prototype system that we have developed. Keywords: navigation system, schedule-oriented, revising itinerary. 1 Introduction Travelers typically collate information related to their journeys from different information sources and integrate them to make their travel decisions. Recently, web-based information services are commercially available for travelers to search for the route and time to get to their destinations by using an urban public transportation network, including trains and buses. In order to obtain necessary information, we have to input a departure place, a destination, departure/arrival time into the system, which provides us with some travel plan options. However, it is often the case that we have to rearrange our travel itineraries due to the change of activity schedules (e.g. change of meeting time) or other reasons (e.g. failure to catch the train). In these cases in order to reschedule our travel itinerary, we have to input necessary information into the system again. If we are on the way, we need to confirm where we are. This procedure is troublesome. If there is a system to rearrange itinerary promptly according to the revised activity schedule, taking into consideration the location of travelers, the convenience of the traveler will be greatly improved.
