For example, as shown in FIG. 2, when a fire occurs in the machine room S ₁₀ , the fire prevention areas A _{11 to} A ₁₄ , A _{21 to} A ₂₃ , and A ₂₅ other than the disaster prevention area A ₂₄ to which the machine room S ₁₀ belongs. whether passage S ₁ is present evacuation route specifying unit 5 determines by referring to the map information storage section 3. When the passage S ₁ exists in a section other than the disaster occurrence section, the process proceeds to S320, and when the passage S ₁ does not exist in a section other than the disaster occurrence section, a series of processing is ended.

In S320, path S ₁ of the shortest distance is identified as the best escape route L _1. Usually, when a disaster such as a fire occurs, it is necessary to evacuate the evacuees M as quickly as possible. For this reason, the passage S ₁ that can guide the refugee M at the shortest distance among the passages S ₁ belonging to the disaster prevention sections A _{11 to} A ₁₄ , A _{21 to} A ₂₃ , and A ₂₅ other than the fire prevention disaster section A ₂₄ is provided. The evacuation route identification unit 5 identifies the optimum evacuation route L ₁ .

In S330, it is determined whether the disaster occurrence section has expanded. For example, as shown in FIG. 2, when smoke from a fire generated in the machine room S ₁₀ travels up the stairs S ₆ and reaches the upper floor, the disaster detection unit 2 in the disaster prevention section A ₁₃ senses this smoke and performs disaster prevention. A detection signal is output. Returning to S310 when the disaster zone has expanded, whether passage S ₁ is present is determined in the disaster zone other than disaster compartments _{A 13 A 11, A 12,} A 14, A 21 ~A 23, A 25, evacuation path specifying unit 5, for example, in an optimum escape route L ₂ S320 identifies add.
