“…To help plane passengers make more efficient use of emergency exits, in China there is an obligation for flight crew personnel to help evacuate passengers in the event of an emergency. In accordance with the requirements of the Annex to Part 25 of the China Civil Aviation Regulations, during the 90-second emergency evacuation experiment, the crew is assigned the following duties: direct passengers to move quickly to the exit, direct the passenger to pick the right exit, follow the evacuation order and ensure safety of passengers [12].…”

The article will explore and collect information about the possible accidents with the Airbus 220-300 aircraft, which is the new and largest aircraft that can be serviced at Riga airport. Previously, such a large plane had not been serviced at Riga Airport, so the article will gather technical information about the characteristics of the Airbus 220-300 compared to previous model planes. As part of the work, passenger evacuation modelling will be carried out with the help of the Pathfinder program, which will be used for emergency simulation. The results of the study may be used to implement further improvements, as well as to ensure more efficient firefighting team work in emergencies in the Riga Airport liability area, as well as other airports serving the Airbus 220-300 aircraft. Reaching the aim will provide an opportunity to look at different variations in the evacuation of people depending on the composition of passengers, behaviour and location of escape exits.

“…In evacuation studies, the area occupied by pedestrians is generally described with a fixed size. Typical models are widely applied by researchers, which include the cellular automata model [34][35][36], the lattice gas model [37,38], the social force model [39,40], and the multigrid model [41][42][43].…”

A cruise ship is a large public place, and it is very important to ensure the safety of passengers during the evacuation process in case of an emergency. This paper proposes a method to improve evacuation efficiency on cruise ships by controlling passengers’ density. According to the construction of the staircase, the space of the staircase is divided into the step and landing areas. On the basis of considering the influence of passengers’ view field and moving characteristics of passengers, the moving rules of passengers in two areas are established. Taking staircases of the cruise ship as the evacuation scenario, the evacuation process is simulated by using the established model. From simulation results, it is found that numbers of evacuated passengers between staircases are very unbalanced and too many passengers gather in one staircase, which lead to serious congestion. By controlling passengers’ density in stairs areas, the minimum evacuation time is the optimization objective and the optimization model is established by using the quantum-inspired evolutionary algorithm and genetic algorithm. The optimization results show that the evacuation time is significantly shortened when the passenger’s density on the staircase is kept within an appropriate range, which proves that the evacuation efficiency can be effectively improved by controlling the passengers’ density.

The risk assessment of runway excursion accidents in the high-plateau airport is a significant part of the airport operations and risk management. This article proposes a method to evaluate the risk of runway excursion accidents in the high-plateau airport with the probability and severity estimations of runway excursion in the high-plateau airport. Firstly, the probability estimation is calculated by combining the correction model and the Bayesian network. The probability correction model considers the runway length required for takeoff and landing, specific ambient temperature, and wind speeds in the high-plateau airport. Then, a high-plateau airport simulation evacuation model of evacuation capacity is established by the VR experiment, and the severity of evacuation in the high-plateau airport is evaluated, combining the endurance of fire products. Finally, based on probability and severity, the quantitative calculation value of risk is given. We also utilize the model on a case study to find the effect of temperature, wind speed, and altitude on this risk index. The results show that the risk of runway excursion accidents in the high-plateau airport is greatly affected by temperature and wind speed. The experimental airport's risk value in February is about 11.8 times of that in September, and the risk value of the high-plateau airport is 7.32 times higher than that in a plain airport. The model successfully simulates the various scenarios at a high-plateau airport and other airports at different altitudes. It is proved that the fire risk of high-plateau airport runway excursion accidents should be paid attention to and provides scientific guidance for the airport's aviation safety management based on the actual characteristics of a high-plateau airport.
