Crowd evacuation model based on path planning

The invention provides a crowd evacuation model based on path planning, and belongs to the field of computer simulation. Knowledge graph fusion mainly exists in the form of graph fusion in practical application. Aiming at the problems of insufficient simulation trueness, low evacuation efficiency and the like of an existing crowd evacuation model, firstly, an improved artificial bee colony algorithm is used for searching a proper evacuation path, indication signs are arranged at key nodes of the path to guide pedestrian evacuation, and the crowd evacuation efficiency is improved. And then the influence of the panic emotion and the evacuation sign on crowd evacuation is added on the basis of the social force model, so that the evacuation model is more in line with the movement condition of the real crowd. The invention provides a specific crowd evacuation model, and compared with a traditional evacuation model, the model provided by the invention can reproduce a typical crowd self-organization phenomenon, is c
