METHOD AND SYSTEM FOR EVACUATION SUPPORT

摘要

A computer implemented method, computer program product, and systems for evacuation support. A computer system includes a first computer (100) configured to store a first graph (110) representing a first physical zone in the populated area, the first graph having at least one first exit node (111, 112, 113) corresponding to at least one exit from the first physical zone. The system further includes a second computer (200) configured to store a second graph (210) representing a second physical zone in the populated area, the second graph having at least one second exit node (211, 212, 213) corresponding to at least one exit from the second physical zone, wherein respective first (112, 113) and second exit nodes (212, 213) connect the first and second graphs. Sensor data indicating a situation in the populated area can be received by at least one interface component (161, 162, 361, 362.) An area computer (300) of the system is configured to calculate an area exit path (212→112) based on the sensor data and connected first and second exit nodes. The first and second computers can determine a first exit path (112→111) from the first graph and a second exit path (212→112) from the second graph, respectively, based on the sensor data and the area exit path. At least one guidance generator component (140, 240, 340) can generate evacuation instructions in compliance with any one of the first, second and area exit paths (112→212, 219→212, 212→112).
