Study On The Early Warning And Emergency Command System Of Dangerous Goods Transportation

Traffic safety and guarding against of disaster are the prerequisite for the development of different transportation method. This thesis selected the road transportation accidents of dangerous goods ,which complexity is higher and has serious environment influence ,as a representative, to explore the laws and the early-warning mechanism of transport accidents.Along with the high-speed growth of our country chemical engineering industry and the mileage of the road construction, the traffic volume of dangerous goods raises quickly. It brings more and more transportation accidents of dangerous goods,and results in many roads potential safety hazard. That the dangerous goods transportation is safe or not influences the road efficiency of the movement and living standards of the people along the road directly. Therefore, our country always pays attention on the safety problem of the dangerous goods transportation very much currently, and increases the safety input of the road dangerous goods transportation continuously. But, not all generic large and medium-sized cities can acquire the huge sum of public finance's devotion. Under the premise that present management method of the transportation safety of road dangerous goods generally fall behind in our country, with the result that the limited resources didn't be made full use, it has important realistic significance to explore the early-warning and emergency conduct methods of the road transportation of dangerous goods, and to raise the safety management level of the existing road dangerous goods' transportation from the point of system.This text selected the road transportation accidents of dangerous goods as research object. It set out from the point of transportation system, putting out searching enquiries, studying the occurrence mechanism and development regulation of the road transportation accidents of dangerous goods for the significance of the society comprehensive management, to build up the early-warning and emergency conduct system of the road transportation of dangerous goods which has intelligent technique, to research objective occurrence regulation of traffic accident and the conversion relation between accidental state and normal appearance of transportation, and put forward the "safety" mechanism which keeps the transportation of dangerous goods to be placed in normal appearance. It has direct value of operation to prevent from the transportation accidents of dangerous goods or deal with transportation accidents properly under the complicated transportation environment, and it has important realistic significance to construct a modernization mechanism which manages the road transportation of dangerous goods and raise the existing level of safety management.The main work and result of this thesis are as follows:On the first part, it was carried up on the foundation of scientifically defining to the dangerous goods content, through checking literature extensively, providing an overview of the present study situation and trend which involve the related fields of early-warning and emergency aiming at dangerous goods transportation at home and abroad from several aspects such as the transportation of dangerous goods, traffic safety management, early-warning theories, emergency ability , road safety evaluation, and...etc.This part set question to investigate the theories foundation of early warning and emergency conduct aiming at dangerous goods transportation through three propositions;and clarified the main contents and methods of the project, basic thoughts and the purpose and meaning of the research.On the second part ,we investigated and summarized the present situation of road dangerous goods transportation in our conutry, carried on risk analysis of dangerous goods transportation from several aspects such as the pedestrians, car, road, management, built up an evaluation model which based on the classical risk theory and the set occurrence risk theory, and launched requirements analysis for the early-warning and emergency conduct system of the dangerous goods transportation.The third part began with the regularity of transportation safety of dangerous goods, It used model of Haiyinlixi to build up a model of inviting disaster mechanism aiming at transportation accidient of dangerous goods, and used catastrophe theory to analyze the mutation process of transportation accidient of dangerous goods. We put forward a system dynamics model of dangerous goods transportation which was based on safety according to the characteristic of transportation accidient of dangerous goods, and carried on an genetic analysis.On the forth part, it put forward an overall framework for the early-warning and emergency conduct system of the road transportation of dangerous goods,used selforganization theory to build up a continuity model and a coordination model of the emergency system of dangerous goods transportation, and concretely investigated the treatment process of early-warning and emergency conduct system of the road transportation of dangerous goods.On the fifth part,we developed a research to the gordian technique for early-warning and emergency conduct system of the dangerous goods. This research mainly included: safety evaluation model of the dangerous goods transportation, Sharing information technique of the early-warning and emergency conduct of dangerous goods transportation, Auto-identification technique based on traffic nformation fusion and emergency mechanism of dangerous goods transportation.On the basis of the fifth part, the sixth part studied the implement Countermeasures of the system.The last part of the thesis summarized for the full text, and predicted the prospects for the following researches.
