TOMSK, Apr 11 – RIA Tomsk. Radiophysics of Tomsk State University (TSU) are developing a system which builds a 3D model for evacuating people in emergency situations. As it is reported on the website of the university, the program will allow to check evacuation plans for various premises, with taking into account possible panic, specificity of structures and materials.

Scientists plan to create a working prototype of the system by 2020. Divisions of the Ministry of Emergency Situations will be able to use it during check of places of mass use, it will significantly reduce the number of victims in case of emergencies, in particular, during fires.

Employees and students of the Department of Information technologies in the study of discrete structures of the Faculty of Radiophysics of TSU work on the project. The project manager – is the employee of the department, Candidate of Technical Sciences Anton Ermakov.

To find a problem

In the process of evacuation in emergency situations, in particular, in case of fire, an important factor is the time during which people are able to leave the dangerous territory, is explained in the message. Both the structure of the building and the condition of the people themselves at the moment of danger can affect the speed of evacuation.

The created system will help to reveal hidden drawbacks of building structures, doorways, ventilation.

The idea of radiophysics is to upload building and space plans into the system, and then, using emergency modeling, check their evacuation plans or develop new ones. The model will take into account the materials from which the walls, floor and ceiling are made – the speed of fire propagation, smoke, smoke toxicity and other indicators depend on it. The system also simulates psychophysical parameters of people in the conditions of panic, predicts the number of fallen, wounded and dead.

“Now there are some methods for modeling of people’s behavior in emergency situations, but in most cases they do not take into account the third dimension, volume, that is, they analyze only two-dimensional space, which significantly reduces the reliability”, – Ermakov is quoted in the message.

He adds that these methods also "greatly simplify the human model": "Eliminate physical parameters and interaction with other people, reduce their movement to the movement of a multitude of particles or two-dimensional figures. The process is similar to the flow of liquid, and fallen or dead people-particles just disappear".

To save a bot

Now the authors of the project can already upload a 3D model of the room into the system, distribute people (bots) and set an evacuation point where the bots should run in case of fire. At the time of launch, each of the bots is counting on the shortest evacuation route and is trying to leave the premises, overcoming obstacles.

“We conducted experiments when the bots left the premises in a calm state, that is, they did not participate in fights, did not fall, did not panic. In this case, the evacuation time is minimal. But we want to put in model psychophysical parameters and physical interaction of people among themselves, because if, for example, one was damaged, then it changes speed, detains others", – says Ermakov.

In the model being developed, the behavior of each bot will be described by an expanded automaton using self-learning models (artificial intelligence). This approach will allow to carry out effective and realistic modeling with the possibility of 3D visualization.

“We plan to involve psychologists in the process of work, because they know typical behavioral reactions, for example, that a child will not run to the evacuation exit, and will look for a mother, and so on”, – notes the head of the Information technologies in the study of discrete structures department of the Faculty of Radiophysics Stanislav Torgayev.

Radiophysicists are also working on creation of a base of materials for interior decoration of premises where their fire prevention characteristics will be taken into account – flame spreading rate, smoke level, toxicity, and others. The presence of such a database will improve the adequacy of the simulation in each particular room.
