This study argues that unsafe behavior is more accurately understood as a systemic outcome shaped by multi-level technological, organizational, and environmental conditions. To address this gap, an integrated human factor risk analysis framework is proposed by combining the STS perspective with safety information cognition (SIC) theory. The framework conceptualizes unsafe behavior as the result of risk transmission through safety information flows, linking system-level risk sources to individual perception, cognition, decision-making, and action. Within this perspective, human factor risk does not arise directly from individual error, but from deficiencies and asymmetries in the generation, transmission, and utilization of safety-related information embedded in the STS. Based on this conceptualization, a system-oriented human factor risk analysis (HRFA) approach is developed to support the identification, assessment, and control of unsafe behaviors across both accident scenarios and operational contexts. The framework is applied to road transportation of dangerous goods in China, a typical high-risk STS. The application results demonstrate that the proposed approach can effectively distinguish the comprehensive risk characteristics of different unsafe behaviors and reveal their underlying systemic causes. This study contributes to systems thinking in safety governance by shifting the analytical focus from individual behavior correction to upstream system conditions and information processes. The proposed framework provides a transferable approach for understanding and managing human factor risk in complex STSs and offers practical implications for proactive, system-oriented safety governance.<\/jats:p>","DOI":"10.3390\/systems14020199","type":"journal-article","created":{"date-parts":[[2026,2,12]],"date-time":"2026-02-12T14:06:16Z","timestamp":1770905176000},"page":"199","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Human Factor Risk Analysis (HFRA) Based on an Integrated Perspective of Socio-Technical Systems and Safety Information Cognition"],"prefix":"10.3390","volume":"14","author":[{"given":"Changqin","family":"Xiong","sequence":"first","affiliation":[{"name":"School of Public Administration, Central South University, Changsha 410083, China"},{"name":"School of Safety Engineering, Jiangxi University of Science and Technology, Nanchang 330000, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yiling","family":"Ma","sequence":"additional","affiliation":[{"name":"School of Economics and Trade, Hunan University, Changsha 410083, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2026,2,12]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"107363","DOI":"10.1016\/j.ress.2020.107363","article-title":"An accident causation model based on safety information cognition and its application","volume":"207","author":"Chen","year":"2021","journal-title":"Reliab.
