Abstract
Today, measures that conducted to “the decrease of bus user” that is the problem of bus industry are difficult to prevail nationally from the problems of the cost to establish these. In this study, we constructed the bus service information system with "user contribution method" that be able to distribute real-time information with row cost, and carried out the public experiment with this system and evaluated the possibility of realization of this system. And to extract the factor of the user contribution, we conducted investigation through the Web research. As a result, we could confirm that the evaluation of the system of the user was high. In addition, we could confirm that the more a person use the application such as Twitter, the more a person distribute the service information. From the above results, it is thought that the system use and the possibility of realization of this system increase if this system improve, considered the factor influence the user distribution about service information.
