Disaster prevention and rescue areas in railway tunnels are essential facilities that support passenger evacuation and rescue operations in the event of a fire. However, the current “Technical Standards for Railway Facilities” mandate uniform installation regardless of tunnel scale or operational characteristics, resulting in cost inefficiency. Accordingly, this study aims to establish a rational installation criterion by conducting passenger evacuation simulations and fire analysis, considering tunnel cross-section, passenger composition, longitudinal gradient, and external temperature as key variables. The results indicate that large-section tunnels exhibit approximately 1.15% longer evacuation distances than medium-section tunnels, while evacuation distance decreases by about 5 m per 1‰ increase in longitudinal gradient. Moreover, moderate-temperature conditions yielded 3–4% longer evacuation distances than winter conditions, and the inclusion of vulnerable passengers reduced evacuation performance to approximately 63% of that of general passengers. Under the most adverse scenario, the minimum available evacuation distances were 523 m for medium-section tunnels and 529 m for large-section tunnels, corresponding to critical tunnel lengths of 1,046 m and 1,058 m, respectively. The results establish 1 km as the minimum tunnel length requiring installation of a disaster prevention and rescue area, improving passenger safety while reducing inefficiencies associated with unnecessary fire-safety facility installation.
