A crowd behavior simulation method and a system guided by a safety evacuation sign

Abstract

The invention discloses a crowd behavior simulation method and a crowd behavior simulation system guided by a safety evacuation mark. The method comprises the following steps of: creating a three-dimensional building model of a scene to be simulated; determining the quantity and the position of the exit corresponding to the scene to be simulated in the three-dimensional building model; marking thelocation of safety evacuation signs corresponding to the scene to be simulated in the three-dimensional building model; according to the number of exits, the location of exits and the location of safety evacuation signs, the road markers in the three-dimensional building model being set in advance, and then PRM algorithm being used to generate all the available evacuation paths, and the paths inthe planning direction of safety exit being marked as one-way paths, paths beyond the planning direction of the safe exit being marked as one-way paths to the outbound exit; importing characteristic data of initializing evacuation crowd; a Dijkstra algorithm being used to find the shortest escape path from the one-way path for the evacuated individuals; in the process of crowd evacuation, an RVO obstacle avoidance strategy being used to simulate crowd evacuation.

AI Technical Summary

Benefits of technology

This technology helps improve security measures by integrating multiple types of signage into an emergency response system that can help people quickly get back up inside buildings or other areas where they may be trapped due to lacking visibility during rescue operations. It also includes advanced features like route planning algorithms (PRM) and visual cues to indicate possible directions along these routes. Overall, this innovative approach improves the effectiveness of crisis management systems while providing better protection against terrorist attacks.

Problems solved by technology

This patents discusses the use of security evacuations for efficient evacuating purposes within buildings like offices and homes. However, there may still exist situations when multiple peoples gather together due to accidental events causing confusion among them who want to leave safely outdoors without being threatened. Existing solutions involve placing signposts near critical locations but they often lead to potential hazards. There needs to develop ways to efficiently guide these peons towards safer routes while ensuring proper evacuative behavior.
