The Local Autonomy Act and ordinances of local governments in South Korea establish various institutional mechanisms for residents to participate in setting and deciding major policy agendas of the community. This study focuses on exploring ways to activate citizen participation in local government safety policy development. The research method was conducted through literature research and case analysis, and was based on the researcher's direct experience as a deliberation support group member. The study focuses on local governments, specifically Busan Metropolitan City, and the operation of the '2022 Citizen Policy Deliberation Group'. This study aims to provide foundational data for activating related systems in other local governments by examining the entire process of citizen-participatory policy development. The Citizen Proposal Deliberation System plays a crucial role in expanding citizen participation and enhancing the quality of policies. Measures to revitalize safety policy development through citizen participation are as follows. First, it is necessary to set the point at which citizen opinions are involved. Second, it is necessary to review and share the feasibility of policy implementation. Third, diversification of the scope of participation in policy deliberation should be considered. Fourth, low-frequency requirements need to be reviewed. Fifth, safety policy discussions focusing on identifying community risk factors should continue.
