Study On The Improvement Of Expressway Emergency Rescue Capability Based On ITS

The capability of emergency rescue is the key index to measure whether quick disposal, efficient cooperation, continuous rescue can be achieved or not during the process of highway emergency rescue. If highway emergencies and disasters couldn’t be rescued in time, they would develop to be public crisis in some extend and area must be supported by great capacity of highway emergency rescue. There are three approaches to solve this question, the first solution is "software "method, to improve traffic capacity through facilities construction&technique improvement; and a second solution is "hardware" method, to improve traffic control management, the finnan is the combination of the former methods. As a kind of comprehensive controlling platform and management method of intellligent traffic, Intelligent Transportation System (ITS) gradually highlight more and more important position in the position of highway emergency rescue, have an un-replaceable advantage to improve emergency rescue capability. What highway emergency rescue capability can ITS really improve? How to improve this capability? So far there are no systematic theories and practices in expressway emergency rescue capability. The study on this area needs to be executed owing to strong practical and theoretical significance.With the instruction of emergency science, regarding the highway emergency capability as the research subject, this paper uses the theories about calamity, transportation safety science, ITS, and social manage comprehensively, to study on highway emergency rescue capability. It conducts a multi-disciplinary cross research on how to improve highway emergency rescue capability based on ITS.Firstly, it referred correlative basic theories. Secondly, the demanding characteristics of expressway emergency rescue (EER in short) were analyzed; the shortcoming of expressway emergency rescue capacity (EERC in short) in China was confirmed by comparison between our current situation and problems of EER system and those in developed foreign countries. It analyzed the demanding structure to enhance EERCs of expressway incidents according to four-dimensional framework of EERCs. Thirdly, with the angle of public management, it discussed the impendence of emergency rescue under the unconventionality emergency circumstance of expressway, explained the conception, features&requirement of EERCs, and put forward the4-dimension (types of disaster, the process of emergency rescue, the capability elements, and the management elements) structure model of EERCs, especially it constructed the structure model of EERC from the process dimension. Fourthly, it analyzes the mechanism of the ITS by the numbers to enhance the EERCs by three kinds of path, analyzed how the key technologies and functions of ITS help to enhance the operating system and emergency rescue system, respectively from four dimensions. Fifthly, it constructed the EER system framework; putted forward the components in the system and their functions, in viewing of the present highway management system applying ITS from the viewing angle of public management. Finally, from the angle of management changing&element reconstructing, the countermeasures to improve EERCs were put forward. Three examples were used to describe how ITS were applied in China expressway.There are four part, eights chapters in all. The first part Putting Forward Questions consisted by Chapter1, manifests the background and significance of theory and realism. The second part Analyzing Questions consisted by Chapter2-5. Chapter2was the theory basis; Chapter3analyzed the demanding characters of EERC and the practice motivation of improving it; Chapter4interpreted the conception of EERC, constructed the4-dimension structure model of it; Chapter5analyzes the mechanism of how ITS help to enhance the EERCss. The thirdly part Solving Questions consisted by Chapter6and7. Chapter6constructed the EERsystem framework; Chapter7proposed the countermeasures to enhance the expressway emergency rescue capabilities. The fourthly part Conclusion consisted by Chapter8, it summarized the research content, abstracted innovation points, prospected the future research work.
