A method for real-time crowd management includes receiving LiDAR point cloud data from area of interest, forming a 3D static surface model of area of interest from LiDAR point cloud data, obtaining real-time CCTV camera images of area of interest, adding real-time CCTV camera images to 3D static surface model to generate real-time dynamic 3D model, identifying dynamic objects in the 3D model, generating a density map of an area of interest, adding density map to the 3D model, identifying which dynamic objects are people, replacing each person with animated character, displaying real-time dynamic 3D model, monitoring the 3D model in the area of interest for dangerous situations, simulating evacuation of area of interest by manipulating animated characters onto pathways leading away from area of interest, forming an evacuation strategy for crowd, and transmitting a notice of the dangerous situation and the evacuation strategy to an emergency authority.
