Research on Crowd Evacuation Simulation in Complex Mountainous Terrain Area Based on Cellular Automata

Abstract:

Recently, the variety of emergent events frequently occurring, such as: great environmental pollution, fire and explosion, toxic gas leakage, disserves human’s living environment, and huge economic and property losses, especially in the rural areas of mountain, where always surrounding by gas fields, chemical plants and other potentially dangerous source, the terrain of mountainous is complex, in the event of crises, the safe evacuation of the population will become a very critical issue. In this paper, through the analysis of the existing evacuation model based on the proposed application 3D surface cellular automata method simulation the evacuation processin complex mountainous terrain. The digital elevation model data, road network and characteristics of the pedestrian are integrated initiatively in the 3D surface CA model. The framework for data extraction, procession and application is designed. A Visualization Software System for three-dimensional simulation of pedestrian evacuation is developed. Moreover, through a case study of some gas well, which belongs to the Puguang gas field in the northeastern Sichuan, it is proved that the model presented in this paper can realize 3D simulation of pedestrian evacuation and predict evacuation time. At last the future work of the model is discussed.
