Abstract
Citizens' concern about safety is increasing, and detached housing areas advertizing safety from car accidents and crimes are appearing. This paper aims to grasp residents' evaluation and to study on problems which should be considered in the process of planning through questionnaires and workshops with the residents in an area with security systems (Juo) and one with traffic calming devices (Aobadai). Generally, the residents living in these areas hold good opinion of them, but there are some problems clarified in the study. The problems about road safety are unclear hierarchy of road networks and residents' understandings of the hierarchy. The problems about crime prevention are the residents' dependence on security systems, lack of territoriality, and inadequate night lighting. It can be said that access control of cars and enhancing territoriality can be tackled together.
