This technical note discusses the primary factors which control the environmental comfortableness in a city center, with emphasis on factors affecting road traffic noise. Information was obtained questionnaires conducted among pedestrians in the city center. The questionnaires included questions about the city center, as well as the residential area of the pedestrians. The results of a comparison of these two areas showed that most people preferred the city center to be an amusement district and their residential area to be close to nature.
