Abstract

Research in this area deal with identifying challenges and developing strategies to improve the protection and support of different mobility groups representatives. They can be an important tool to create a society with equal opportunities and to reduce risks during emergency situations.

The authors emphasize the importance of computer simulations for analysis and improvement of evacuation strategies. These tools allow testing different emergency scenarios, help to improve infrastructure and planning different structures for providing maximum safety.

The work is dedicated to the experimental research on evacuation simulation оf mixed flows consisting of different mobility groups (M1, M3, M4) in case of fire. The aim is to compare the results of simulation with experimental results and to make conclusions about future use of obtained data in scientific exploration as well as establishing relationships between the evacuation participants’ movement speed and the flow density.

Analytical and computer modelling methods were used to achieve the goal and implement the set tasks. Movement simulation results of mixed flows evacuation were analysed.

Evacuation features of people with different mobility in case of fire were studied. The results of simulation were compared with experimental results. Conducted work is important for evaluating the reliability of studies and for confirming the model suitability for father research. The work is also aimed at creating an empirical database of the movement parameters of different mobility groups’ representatives during evacuation from a building in case of fire.

Modelling was carried out in two stages. The first block of models was intended for a real-life experiment preparation of different mobility groups’ representatives. These modes were used for obtaining an empirical database of mixed evacuation flows movement parameters. The initial data for this calculation were used in accordance with [1]. The second block of models was based on empirical data obtained during the experiments.

The results of this work can be used in further experimental studies. They can help in determining the speed-density relationships for each flow configuration.
