Status of the Arts of Japanese ITS and the Future Aspects

Abstract

After reviewing the history and status of Japanese ITS, the author shows that safe driving support systems do not spread into the market. Then the author suggests that one of the causes of this is to be developed by only natural scientists and engineers. Usually drivers have a kind of nonlinearity that is difficult for natural scientist or engineers to understand and there are some interactions between drivers and safe driving support systems developed by them. This interaction is not considered by natural scientists or engineers. In contrast with this social scientists are strong to study this interaction. The author, finally, points out the importance of the collaboration between social and natural scientists.
