Abstract

We have been developing mobile passenger support systems for the public transportation. In this application field, various kinds of data must be handled and integrated. Examples of such data are route information, fare information, area map, station map, planned operation schedule, real-time operation schedule, vehicle facilities etc.Depending on the user situation, different information should be supplied and personalized. In this paper we propose the human support system used in the multi-channel data dissemination environments. There are two kinds of data dissemination sources in the proposed system, fixed and moving. The moving sources are transportation vehicles such as trains and buses. Although most of user requests are processed by means of integrating information transmitted by data dissemination method, on-demand process should be also required.As the system must be used in the case of emergency when the system load is expected to be very high, we will not use a centralized system. Integrated personalization and filtering are performed at each terminal. In this paper we will discuss efficient procedure to handle dynamic integration, dynamic personalization and dynamic filtering using multiple data dissemination channels and on-demand data channels. Current prototype system developed to be used visually handicapped passengers is also shown.
