In this research, the authors analyzed how a social experiment and its information provision affect silent group's consciousness about traffic safety project in a residential neighborhood. Conducting social experiments turns traffic management plans into reality in limited time, however, some residents including the silent group may not be aware of the experiments' impacts on their neighborhood because of their place of residence or life pattern. The authors tested the hypothesis that active provision of information about the effectiveness of a social experiment encourages the silent group to accept the experimented plan with a case study. The case study is a implementation of speed humps in a residential area in Bunkyo ward, Tokyo. In conclusion, it was suggested that information provision of the experiment contributes to both silent group and non silent group's acceptance of installing speed humps permanently.
