The Mechanism Of Hazard Diffusion From Transportation System Under Extreme Weather

Extreme weather disrupted transportation system research diffusion processhazards disaster response and crisis management is an important research topic.Through in-depth analysis of weather disasters paper transport system damage harmdiffusion process for the management of extreme weather caused by the public crisismechanism to provide basic support.This article will transport system disaster weather in the course of the crisistriggered by the collapse as a nuclear process, and its collapse sequence is from thephysical network to the social network, triggering a crisis. This helps in-depthknowledge and understanding of the hazards of meteorological disasters hazardsdiffusion process, and thus for the bad weather damaged transport system to providecrisis management enlightenment.Research has focused on the coupling of the diffusion process hazard analysisand embeddedness characteristics, the main contents are as follows:The first defines the concept of weather disasters, disaster weatherclassification. Analysis of extreme weather conditions on the road, vehicles,travelers, traffic control and other factors affecting these traffic. Fault tree tool useweather disasters causing traffic system failure types and characteristics wereanalyzed. This damage is extreme weather hazards diffusion transport systemsprovide theoretical support. Second, extreme weather damage to transportationsystems diffusion model to study the hazards. After extreme weather damage toother transportation systems infrastructure damage caused by the coupling ofdiffusion effects on social networks and governance network embeddedness harmcaused by diffusion effects; analysis of system dynamics and embedded coupling oftwo modes spread of hazards role and influence. Combined in2008in the Southsnowstorm harm diffusion chains of causal analysis, on which the variousevolutionary path variables analyzed further pointed out that in the post-disasterweather in the transport system from the physical network to the dangers of socialnetworks evolutionary path. Third, extreme weather damage diffusion transportsystem of governance dilemma hazard analysis. Coupling and embeddedness fromthe perspective of the harm caused in the spread of extreme weather governancedifficulties. On this basis, that the extreme weather damage caused by the interactionof transport system, combined with relevant case (2008snowstorm Case) analyzedthe manifestations of this interaction, and the interaction of the coupling interactionand embeddedness analyzed and found to endanger diffusion interaction with boosting.Systems Analysis transportation system after extreme weather damage harmdiffusion process is conducive to further improve the effect of crisis management;diffusion process of hazards that exist coupling, embedded, interactive impactanalysis, help us to understand the diffusion process hazards, thus contributing tothe design and management measures related to the development.
