区域客运交通系统运行效率及能耗强度优化方法研究

It is well known that improving transport effeciency and meanwhile decreasing energy consumption intensity have crucial effect on the sound operation and sustainable development of a regional passenger transport system. However, there have been still inadequate studies in this regard till now on the effective comprehensive optimization methods from the systematic perspective. Therefore, this research focuses on the work of newly developing dynamic optimiztion methods to realize the rational combination of the operation efficiency and corresponding energy cost intensity of a regional passenger transport system in view of its macro-, meso- and micro-actions in an integrated manner. .In the systematic viewpoint, the effect mechanism and interactive relationship of various factors affecting the operation effeciency and energy cost intenstity of a regional passenger transport system are first analyzed quantificationally in this study. Such analyses of e.g. the establishment of certain standards of the transport industry, the arragement of some tranport hubs, the choice of a transport route, etc. are made in consideration of the dynamic interactions of macro-policies, meso-measures and micro-techniques for different kinds of regional passenger transport markets. Moreover, serial changes of the operation efficiency and energy consumption intensity of a regional passenger transport system because of the interactive effect of e.g. the afore-enumerated factors on multi-levles are evaluated from the systematical perspective. In addition, the changes of social and economic benefits are also studied based on the dynamic analysis and systematic evaluation work. Furthermore, the dynamic optimiztion framework is accordingly established to effectively analyze, evaluate and optimize the operation of a regional passenger transport system with the objects of both the improvement of transport efficincy and the decrease of energy cost intensity. Finally, the newly developed methods are applied to study and making suggestions on coordinately ameliorating the operation efficincies and energy cost intensities of certain typical regional passenger transport systems..By making effort to establish the dynamic and systematic optimiztion analysis framework with the assess of representaive examples, it is able to reasonably provide convincing decision-making supports for the efficient operation and sustainable development of a regional passenger transport system in different social and marketing circumstances.
