A Study on Entrance Design of Speed Limit Zone based on Users’ Consciousness in Japan

Zone 30 system is being promoted into the community roads in Japan now. In order to get an effective design alternative for the entrance of the zones, a study is conducted by taking the Motoshiro region in Toyota City as the objective area and by considering the users’ consciousness. The eight alternatives of entrance design based on the basis of the real community road background, including colour pavement, locating of speed limit signs, limit road marking, road edge marking, pedestrian crossings, narrowing of road and their combinations, were shown to the respondents. The study has been made incorporating the users’ personalities when driving cars. The statistical analysis is carried out from many viewpoints by considering different respects. Then the proposals are summarized for promoting the speed limit zones in Japan.
