區(qū)域交通應(yīng)急保障體系構(gòu)建研究
[Abstract]:Since 2008, the focus of emergency management in China has been gradually shifted from emergency relief to pre-disaster prevention. Based on this, the construction of traffic emergency protection and prevention system has been carried out in this paper. This paper discusses the construction of traffic emergency protection network and the construction of regional emergency linkage mechanism in software, which is based on a kind of emergency concept: hierarchical response, hierarchical governance. First, the regional traffic emergency support system is an important part of a regional emergency support system, and it contains many sub-systems. Generally speaking, many sub-systems of traffic emergency support system are mainly divided into hardware system (road resource system, emergency platform, material equipment, etc.) and software system (plan system, financial system, legal system, operation mechanism, etc.). Secondly, there are many methods to construct traffic emergency support system. On the basis of summarizing the existing research results, the paper puts forward the establishment of traffic emergency support network and emergency linkage mechanism to build traffic emergency support system. The traffic emergency support network mainly covers the road network and emergency material allocation of hardware system, and the software system mainly discusses the construction of emergency linkage mechanism. Traffic emergency support network mainly consists of traffic emergency nodes and emergency channels (paths). Traffic emergency node is the carrier of traffic emergency system in a region or city, and its main function is to provide traffic emergency protection for the emergency process. On the one hand, based on the analysis of the importance of emergency nodes, the division of levels and the definition of emergency scope, the traffic emergency nodes are reasonably distributed. Traffic emergency nodes are divided into three types: regional emergency center node, regional emergency service node and local emergency service node. Fuzzy clustering method is used to partition and Matlab is used to complete the operation. The definition of emergency scope of emergency nodes is mainly discussed from three aspects: emergency time, emergency capability and administrative attributes. On the other hand, aiming at minimizing evacuation, rescue time and the possibility of congestion and delay in the emergency area, a model is established to optimize the emergency support network. In view of the emergency channel optimization of poor climate conditions and fragile and sensitive geological structure, this paper puts forward a multi-path optimization strategy, and applies the Analytic hierarchy process (AHP). The main evaluation indexes of the new route in the channel are the transportation capacity and the disaster resistance ability between the existing traffic emergency nodes. Emergency resources are divided into a number of categories, according to the level of emergency node configuration corresponding types and quantities. In the aspect of software system, it mainly discusses the establishment of emergency linkage mechanism, the construction of emergency linkage mechanism within longitudinal traffic emergency response system and the construction of emergency linkage mechanism between different departments under the lateral emergency management system. These two aspects are discussed and analyzed from the organizational structure and operational mechanism of the mechanism, the purpose of which is to form a "unified command, efficient and orderly" emergency linkage mechanism. Finally, the case analysis, combined with the Chongqing Comprehensive Transportation Research Institute of Chongqing traffic emergency support research and related data, using the proposed traffic emergency support system construction method to get Chongqing traffic emergency support network construction. Establishment of emergency resource allocation and emergency linkage mechanism.
