INVOLVEMENT WITH TOPICS OF SURVEYS AND SILENT GROUP IN SURVEYS FOR MICRO AREA TRANSPORTATION PLANNING

Abstract

There are no specific measures to formulate public opinions and no clear guidelines for positions of people who do not express their opinions, whom the authors call the “silent group,” in any planning processes. In this research, the authors analyzed a relationship between a silent group and their involvement with topics of questionnaire surveys for a micro area transportation planning. In conclusion, the authors found that a silent group's involvement with the topics shown in the questionnaires such as traffic problems in their residential area was weaker than that of people who responded to the questionnaires in time. If people thought that one of the questionnaires picked up only roads they didn't think danger, they tended to be silent despite their recognition of danger in the whole area.
