Abstract
Human behavior is a result of stimulation from the environment. If the stimulation is positive for cars, the result will be car use; and if there is positive stimulation for pedestrians, there will be more pedestrians. The same effect may be observed for public transport and cycles; theoretical and experimental studies based upon this theory support previous findings. Japanese Ministry of Construction and OECD/Road Transport Research Programme held the seminar on "future road transport systems and infrastructures in urban areas" in Chiba, Japan on 4th - 6th june 1991 sponsored by the Japanese organizing committee.
