The obstruction of Community Emergency Corridor System has become one of the critical factors contributing to fire-related casualties among residents, posing a serious challenge to both individual life safety and the effectiveness of public safety governance. Current Community Emergency Corridor System encounters significant systemic bottlenecks in triadic space coordination, with information space lag emerging as a critical constraint on emergency response. An integrated assessment framework is urgently required to address this coordination dilemma. However, existing research predominantly focuses on a single space and lacks a comprehensive evaluation framework for the coordinated accessibility of physical, social, and information spaces. To fill this gap, this study adopts a triadic space perspective by examining 77 typical Chinese communities as research subjects. It employs the Entropy Weighted TOPSIS method to construct an evaluation index system for assessing the accessibility of Community Emergency Corridor System, aiming to systematically measure their levels of accessibility. The findings reveal the following: (1) Overall, the accessibility of Community Emergency Corridor System across triadic space demonstrates uneven development, highlighting systemic coordination bottlenecks within community emergency response networks. There is an urgent need for structural optimization through the reorganization of spatial elements; (2) Significant spatial disparities exist among triadic space, with social space accessibility surpassing that of physical and information spaces; (3) Regionally, communities in Northeast China exhibit significantly higher accessibility to emergency corridor compared to those in East, Central, and West China. Given the disparities in development levels and community structures across different regions, this study proposes strategies to overcome multi-agent coordination challenges, bridge digital platform gaps, address infrastructure bottlenecks, and enhance public emergency awareness, aiming to systematically respond to urban fire risks and improve the overall accessibility of the community emergency corridor system. The triadic space evaluation framework and methodological pathway developed herein provide a replicable analytical tool for emergency management in the context of urban fires, offering valuable insights for Chinese communities and other high-density regions seeking to strengthen fire resilience governance.
