The Emergency Management Of Highway Transportation In Sudden Disaster

China is one of countries which suffer from natural disaster severely. The disaster is in wide varieties and happens frequently, and the loss is above 100,000,000,000 Yuan each year. The ice-snow disaster and the Wenchuan earthquake both discovered the potential safety hazards of infrastructure and emergency management system's imperfection, which urged us studying on the prevention of the public emergency, the early warning system and the countermeasures.The ice-snow disaster is a severe public emergency, in which the most important question is the lacking of the early warning planning. The past study on emergency management is from the perspective of the management, and under the background of the events of fire disaster, earthquake, public health, chemical pollutions. However, the characteristic and influence mechanism of ice-snow disaster have challenged the present emergency management system. By strengthen the emergency management, construction of the social early warning mechanism, the emergent event mechanism and the social mobilization mechanisms, as well as building up a public emergency system are meaningful to the national security.This paper from the background of the ice-snow disaster in Hunan province, and makes an analysis to the influence mechanism to study the traffic emergency management. This paper, first sums up different kinds of the emergency management theory, and then summarizes the present emergency management research trends. And then it makes a review to the emergency management from the angle of emergency early warning and emergency treating. Furthermore, it compares the emergency management system in home and abroad, such as America, Russia, Japan, from the perspective of the law system, organization system, and management system and emergency command system to get the enlightenments for China. Based on the prediction model, it tries to make an analysis to the seasonal characteristic of the public traffic and make a prediction to the Beijing-zhuhai expressway in Hunan province, and make an analysis of the ice-snow disaster on the traffic flow. After summing up estimation method in the natural disaster loss, it describes the weather and the traffic of the Hunan ice-snow disaster in 2008, and it estimates the loss from the perspective of the declining of the vehicle flow, blockage and the traffic event. The sixth chapter builds up the goal programming model to make an analysis to the path selection in the emergent event from the angle of the driver and manager, and make a study on the shunt system and optimization, and make an empirical analysis to the optimal shunt system to the ice-snow disaster in Hunan province in 2008. The seventh chapter provides some advices from the views of the disaster management system, the treatment system and the information disclosure mechanism, quicken the building up of the disaster management law, the mobilization mechanism to improve the social ability to handle the emergency, the science-tech reserve, the basic traffic infrastructure and the measures to cope with the traffic bottleneck.This paper focuses on the emergent management system, especially the emergency management, to provide some methods for emergency management of the emergent event, and it promotes the study on the theories, methods and application in emergency management and makes some devotions to the building up of the emergency management system.
