System for assisting the routing of individuals in their way out of a venue, the system comprising: - a digital layout of the venue; - a hazardous event detection device, detecting the occurrence and the localisation of a hazardous event; - a plurality of mobile devices; - a local network communication system, LNC, permitting communication between the mobile devices; - an indoor location tracking system, ILTS, comprising means for localizing the real-time position of each mobile devices and/or a network of cameras and a convolutional neural network analysing data received from the cameras for localizing each individual through Face-Body-Object recognition; - a database (20.11) of pre-simulated scenarios of evacuation, comprising an optimum evacuation plan based on the digital layout of the venue, properties of the hazardous event and the localisation of the individuals; - an AI-based rescue system comprising: - an estimation module (2.1) which estimates the duration of evacuation and death toll for several evacuation plans, based on the hazardous event, on the real-time position of the individuals and on the pre-simulated scenarios, and selects an optimal evacuation plan and/or offers the responsible of the evacuation to select an evacuation plan potentially amongst a pre-selection of evacuation plans established by the estimation module; - an emergency state planning module (2.2) providing respective directions to each individual for evacuating the venue according to the selected evacuation plan; - a lost individual identification module (2.3) which identifies a lost individual based on a comparison between the real-time positions of the individuals and the selected evacuation plan, and/or based on data retrieved from the LNC; wherein upon detection of a lost individual, the AI-based rescue system performs at least one of the following actions: - informing the responsible of the evacuation of the identification and possibly the location of the lost individual; - instructing staff members to assist the lost individual; - broadcasting oral or optical assistance to the lost individual through the speakers of the venue or through floor lights appropriately lit up; - broadcasting the physical characteristics of the lost individual; - updating the evacuation plan based on the location and physical condition of the lost individual. - a digital layout of the venue;
