摘要
The efficient and flexible impacts of transportation system have reshaped the way urban makes development. Therefore, the planning of highly effective transportation system is increasingly taking into consideration the full decision-making cycle of urban development planning. There, however, exists certain gap between the dynamic and ever changing planning and a given set of operational, managerial, and financial goals and objectives. Upon such an actuality, continuous monitoring, effective supplement, contrapuntal revision and in time updating of drafted planning, seek, identify, minimize this difference and optimize the planning along its implementation process. To be effective in this purpose, the primary purpose of this paper is to introduce the formulation of adaptability degree as a performance based methodology to assess the adaptability level of transportation system to urban development requirement. Sixty indexes are chosen to construct an index system and then adaptability index is estimated by an improved AHP approach, which utilizes the SVD method to improve the required precision of matrix with acceptable consistency weight and detect and amend the significant elements via distance and proximity so as to improve the whole consistency. Taking Shandong Province for the case study, experimental results indicate that the adaptability degree of the system is in an increasing state, which provides robust and effective support for decision-makers working on a range of problems and in various circumstances.
