Abstract

Forecasting the spread of fire in the aftermath of an earthquake by simulation is useful for prompt fire fighting and selection of resident evacuation routes. We have been developing a simulation system using Cellular Automata (CA). The map data of the simulated region is necessary to forecast a fire by CA. This research introduces an electronic housing map into the fire simulation system for improving the lattice-map-generation process. In the system designed in this study, a lattice map can be prepared by reading the color information of the buildings as soon as a region is specified. This process has greatly shortened the time to create the lattice map and simulates accurate shapes of the buildings. Moreover, a method is proposed to arrange cells suitable for the urban districts of the Gobo-Hidaka area, in which a fire was simulated.
