“When the force of public opinion gathers”: From online advocacy to policy engagement on pedestrian safety
研究台湾行人安全议题中，第三方倡导如何从线上动员转向线下政策参与，通过访谈揭示社交媒体如何推动议题显着性并促成部分政策回应，但制度碎片化与利益阻力限制了结构性改革。
Pedestrian safety has emerged as a critical policy issue in Taiwan, where persistent road fatalities and car-centric planning have fueled public concern. This study examines how third-sector advocacy has evolved from online mobilization to real-world policy engagement, influencing transportation governance. Drawing on qualitative interviews with advocates, policymakers, and planners, the research explores how social media platforms enable advocacy coalitions to build visibility, mobilize public discourse, and press for institutional change. The study employs the Advocacy Coalition Framework and the Multiple Streams Approach to analyze how shared beliefs, policy learning, and political opportunity shape the trajectory of advocacy. Findings show that online advocacy catalyzed issue salience and participatory pressure, leading to partial policy responses such as painted sidewalks. However, incremental gains remain constrained by institutional fragmentation, stakeholder resistance, and the absence of structural reform. The study contributes to existing literature on participatory transport governance by demonstrating how hybrid advocacy models, linking digital and real-world engagement, can influence policy processes while facing persistent limits to institutionalization.
