Specific analysis is on the disaster index in four aspects: informational sign, fire-fighting equipment, evacuation capability and refuge. 17 indexes are extracted reflecting the disaster evacuation performance, the weights of each disaster-prevention index are defined by Analytic Hierarchy Process (AHP), and fuzzy comprehensive evaluation method is adopted to conduct comprehensive evaluation of safety performance. The established disaster-prevention index system has practical value and significance to improve the disaster-prevention capability of urban underground transportation junctions.
