Hazardous chemical diffusion model-based traffic emergency command method

Abstract

The invention discloses a hazardous chemical diffusion model-based traffic emergency command method. The method comprises the steps of 1, collecting event information; 2, performing prediction early warning on a pollution status around an accident site of a hazardous chemical vehicle, forming an environmental pollution comprehensive prediction and analysis model, and predicting a flow situation, a diffusion region and an evacuating route of pollutants; 3, performing unified display on early warning information, an influence range and a development situation obtained by calculation simulation, and other information of an event through a GIS map for analysis decision, thereby obtaining an optimal command rescue plan; 4, performing emergency resource scheduling, information release and traffic guidance diversion; and 5, performing maintenance storage, analysis and statistics on an event case.

Description

technical field [0001] The invention relates to a traffic emergency command method based on a hazardous chemical diffusion model. Background technique [0002] In recent years, the road transportation of hazardous chemicals has been increasing with the rapid development of my country's chemical industry. According to statistics, nearly 90% of hazardous chemicals in my country need to be transported through expressways. In recent years, my country's annual road transportation of dangerous goods is about 200 million tons. Among them: hundreds of thousands of tons of highly toxic cyanide, 100 million tons of flammable and explosive oils, and the logistics of hazardous chemicals has gradually formed. A large number of flammable, explosive, and corrosive substances are transported across the country, which is equivalent to forming a mobile source of danger. The number of hazardous chemical transportation accidents that occur every year is on the rise, causing thousands of casualti...

AI Technical Summary

Problems solved by technology

[0013] (1) Hazardous chemical leakage events contain a lot of state information, including hazardous chemical information, weather, road surface, accident, maintenance schedule, bayonet, charging, video and other information, and each state has different attributes. , the existing system does not fully collect and comprehensively utilize the state data, and the results obtained have low accuracy and credibility

[0014] (2) The budget results calculated by some diffusion models are not displayed in conjunction with GIS (Geographic Information System, Geographic Information System or Geo-Information system) maps, the data is more complex, not intuitive, and the efficiency of decision-making support is low

[0015] (3) The intelligent matching of traffic emergency plans is the key link to shorten the emergency rescue decision-making time. Real-time and effective emergency rescue plans can be obtained, and scientific and reasonable judgments can be made at the first time in the command. The collaboration between materials is optimal, and the existing methods are obviously insufficient in intelligent matching of emergency plans for hazardous chemical leakage incident response, lack of matching or low accuracy of matching results
