Mixed mode large urban area tsunami evacuation considering car-pedestrian interactions

抄録

This paper presents a multi-agent based evacuation simulation software capable of simulating mass mixed mode evacuations of large areas including sub meter details of the environment. A mathematical framework is introduced in order to provide a framework for the specification and description of the software, enabling to compare the developed multi-agent system with other existing evacuation simulation tools and identify underlying differences and areas of improvement. Details of the high resolutions environment, including the modelling of dynamic changes like earthquake induced damages, etc. are briefly explained. Furthermore, the basic constituent functions of autonomous agents, which enable them to perceive their visible surrounding and interact with it and neighbouring agents, are also briefly explained. The mixed mode interactions are briefly presented along with its validation results. Demonstrative mass urban area mixed mode evacuation scenarios are presented in order to highlight the need of incorporating detailed models of environment and the complex agent functions and interactions. Most of these scenarios cannot be simulated with the simplified models without sacrificing accuracy or making broad assumptions.
