Multiagent Based Tsunami Evacuation Simulation: A Conceptual Model

During emergency situation, such as a large-scale tsunami or other disastrousevents, people evacuation may lead to more fatalities when it is conducted without a proper escape strategy. The ability to evacuate a huge number of people within a very limited amount of time is certainly required. Evacuation drills are therefore necessary to acquire an optimal escape strategy. Unfortunately, we have to deal with both financial and practicalchallenges for conducting a regular and meaningful drill. To overcome these challenges, one solution would be to develop the evacuation simulation model. Despite its limitation to mimic the real-life situations, simulation may provide practical ways of minimizing the negative consequences as well as useful insights to escape strategy. In this paper, we describe a conceptual model of multiagent based tsunami evacuation simulation (TES). The model formulation and description would follow the ODD (Overview, Design concepts, andDetails) protocol, which is a standard protocol widely used by agent-based modellers. The proposed model may serve as a framework for TES that offers the following features: estimate the clearing time or the time needed by people to leave the tsunami inundation area, and identify the potential bottleneck or congestion locations. Using the proposed conceptual model, we consider constructing the TES for Calang district, a coastal area in Aceh Jaya regency, for future work
