The goal of this paper is to create a model simulating a part of the terrorist attack in the Tokyo subway in 1995 using sarin gas and its implementation using AnyLogic software. Another goal is to find possibilities of minimizing the losses using what-if scenarios. The model should serve as a tool for further investigation of the attack and propose...

Current situation of international violent terrorism is severe. Public places with high density crowd are more likely to be attacked by violent terrorists. Terrorist attacks such as car bombs are one of the very common and harmful types. “10•28” Beijing Golden Water Bridge Attack is a very typical example. Based on the case analysis of the Beijing Golden Water Bridge Attack, this paper established a simulation model of a car bomb terrorist attack on the basis of the social force model of the Anylogic software platform and conducted simulation experiments on the impact of route choice on pedestrian casualties in the car bomb violent terrorist attack. The simulation results show that: there is minimal damage to pedestrians under a specific route. These conclusions are of great practical significance for the placement and arrangement of safety protection facilities for large-scale event venues.
In recent years, stabbings have occurred frequently around the world, often causing serious casualties and property losses. Therefore, using evacuation model to simulate and analyze this type of attack mode is of great significance to personnel safety and social stability. However, in the simulation process, the lack of interaction rules between pedestrians and attackers will seriously reduce the accuracy and credibility of the simulation result. Herein, this article focuses on the pedestrian evacuation under stabbings, we proposed a risk field model for pedestrian movement, its formula refered to the continuous point-source diffusion equation in unbounded space. The influence of the surrounding environment on pedestrian movement was considered comprehensively to set the direction of the force exerted by the attacker, pedestrian movement rules and exit selection mechanism were introduced in details. At the same time, we discuss two different attack strategies for attackers, and carried out virtual reality experiments to analyze the experimenter’s attack modes and compare them with the two pure strategies. Multiple simulations are conducted on the basis of the model to explore the physical significance of model parameters and the influence of attack mode and location on evacuation, and to explore the mechanism of pedestrians’ selection of exits under the condition of multiple exits. At the end of this paper, the simulation results are summarized and suggestions for evacuation under emergencies are provided, which may be helpful to the simulation of pedestrian evacuation under emergencies in the future.
