Abstract

The invention discloses a dynamic data driven modeling and simulation method for crowd evacuation and transportation behaviors in a sudden-onset disaster. According to the method, real-time disaster information is acquired by analyzing high resolution remote sensing images, a simulation model of a landslide and other natural disasters is used for outputting virtual data about disaster evolution, a crowd simulation platform describes individual behaviors on a disaster circumstance, and then real-time online modeling of the landslide disaster is achieved. A decision is made for the individual behaviors according to environment information by describing individuals through several different attributes and defining several different environment description attributes. Experiments prove that through the method, better crowd evacuation efficiency and availability are achieved in an actual rescue activity in the landslide and other natural disasters.

Description

technical field [0001] The invention belongs to the technical field of simulation modeling and relates to a dynamic data-driven modeling method, in particular to a remote sensing data-driven, sudden disaster modeling and crowd simulation method. Background technique [0002] The suddenness and unpredictability of natural disasters can easily cause loss of life and property of local people and damage to the environment. Therefore, it is necessary to formulate a reasonable rescue plan. Most current research in this field is based on real event data or physical experiments. However, these research and experimental methods are neither suitable for planning nor require large investment. [0003] Modeling and simulation technology is a key technology in the field of science and engineering. The application of this technology to the field of natural disaster prevention and control is a typical example. Through modeling and simulation, it can not only show the evolution process ...
