Abstract
It is required to change personal behavior and social policy toward a sustainable society. This study aims to survey preferences on personal daily travel modes and social transport policy with the reasons, and analyzes correlation with personal attributions and morals. As a result, it is found that more than 40% are using passenger cars mainly as a daily travel mode, but public transport is chosen by more than 40% as a travel mode to be improved and access to public transport is chosen as a key factor to decide residential location. As for a policy they would promote as a mayor, public transport is supported by over 50% mainly because it is user friendly for everyone. These results imply that such survey makes it easier for government to introduce policy changes. It is also suggested that public transport policy is supported not only for eco-friendly or for potential availability, but also for morals indirectly such as legal conscience and self-conscience.
