On-foot evacuation model using virtual tessellations network: A proposed method for tsunami evacuation planning

Abstract

This study aims to analyze the tsunami disaster evacuation model using the current existing method, which uses only existing road, and compared with the proposed method using three types of tessellation as virtual network. The research is using Network Analysis solver within ArcGIS environment to compare 4 types of network distance with the real-world path as the standard. The result of this study has shown that the use of tessellation as a hexagon tessellation as a virtual network can help justify the real situation in the evacuation process much more precise rather than using the current existing method (standard method).
