Abstract
Since 1960's, Motorization continues in Japan. It brings various merits for our life, but also brings a lot of demerits such as traffic congestion, traffic incidents, environmental problems, and declination of shopping area on city center. In this study, we focused car restriction of shopping area to activate city center. We hypotheses that shop owner whom voice in the negative about car restriction does not know the fact such as "pedestrian desire car restriction", so the information of the fact would given to them, then their attitude towards car restriction would change as those in the positive. We did before and after surveys to verify this hypothesis, and the results of analysis suggested the hypothesis.
