Abstract
As street improvement for pedestrians has received more attention as one of measures for city-centre regeneration in Japan, it has become important to develop evaluation systems for designing roads to contribute to walking promotion. However, the conventional approaches have been applied only to evaluating individual physical factors of street environments without considering their comprehensive perceived factors that influence walking behaviours. This study aims to evaluate the quality of street, using the comprehensive perceived factors based on the hierarchy of pedestrian needs. It first develops the evaluation model to estimate the outcome index of quality of street with pedestrians' preference parameters and satisfaction levels for perceived factors of convenience, comfort, and safety. Then, using the data of a questionnaire survey in CBD of Takamatsu, 2 case-study areas are evaluated. The results show that pedestrian needs for street environments vary by age and visit frequency to CBD, and the quality of street is higher for groups with the higher visit frequency, if pedestrians are highly satisfied with the street environment.
