In recent years, the removal of traffic signals that are no longer needed is being considered to review how traffic safety facilities are maintained. Among traffic signals, single-flashing traffic lights are being removed nationwide on a priority basis. However, residents do not always show their approval for their removal because of the traffic safety. Therefore, in order to promote appropriate consensus building, it is necessary to clarify the factors that influence residents' approval or disapproval of the removal of these lights. In this study, we analyze residents' attitudes toward the removal of single-flashing traffic lights and the factors that influence these attitudes. As a result, it was found that it is possible to increase the awareness of residents in favor of the removal of single-flashing traffic lights by providing appropriate information and by holding face-to-face explanatory meetings.
