Network Operation-Based Urban Rail Transit Emergency Conducting And Management Evaluation

At present, urban rail transit in our country has entered a high-speed development period. The majority of city’s urban rail transits turn to a new network operating situation under the old single-line operation transformed into a multi-line multi-format one. Under this condition, the complexity of network structure,the multiplicity of operating standard besides the big area of infection and the serious consequence after a sudden accident occurred. These bring many difficulties to the emergency command management. As a result, the scientific and reasonable method of emergency command management for prevention of urban rail transit reducing sudden accidents and decreasing accident damage is of great significance.An emergency command management evaluation of urban rail transit is a nice precondition for establishing, perfecting and improving the ability of it. Through the establishment of accurate model and evaluation of urban rail transit emergency command management ability, finding the problems existing in the emergency command management process, repeatedly to improve and perfect, then getting a better emergency command management ability in order to reducing sudden accidents and decreasing accident damage.Regarding to the domestic and foreign emergency capability evaluation, the author has researched in depth. However, the research result showed that nowadays most of domestic and foreign index mostly basing on the research results of predecessors or subjective thoughts. By this way, the index system certainly is lacking in convincing, its rationality is yet to be proven. In view of this, it was introduced that the basic situation of a variety of typical accidents happened in all the countries around the world since the birth of urban rail transit for150years. Based on the influencing factors which got from analyzing the cause of accident and the disposal process deeply, the preliminary evaluation index system was established including4first-level indexes (personal quality, facilities, management mechanism and social control) and30second-level indexes.As the evaluation index based on accident analysis is comprehensive but rough, it’s necessary to simplify preliminary evaluation index system for reflecting the accuracy of model. Rough set theory owns the functions that removing redundant indexes and extract the key one. Based on the simplicity attribute of rough set, the selection model of urban rail transit emergency command management evaluation index was established and based on information and impotence of attribute principle of rough set, the model which determined by index was also established. In this article7cities whose operating time of urban rail transit are longer were selected as research objects (Beijing subway, Shanghai subway,Guangzhou subway, Shenzhen subway,Hong Kong subway,Chongqing light rail,Chengdu subway). By means of assigning the preliminary established evaluation index system which got form field survey and expert consulting, the information system of urban rail transit emergency command management was established. Combining index selection model and determining weight model, we got21the most simple indexes and the comprehensive weight. So each index was calculated by using the linear weighting method, and obtained the comprehensive evaluation results finally.
