The synthetic urban public transport development assessment methods mainly focused on grey cluster method [8, 9, AUY922 structure 14], entropy weight matter-element analysis model [4], fuzzy synthetic assessment method [12, 13], multifactor fuzzy assessment [15], and so forth. In this paper, a multitiered urban public transport development level assessment index system for the conventional bus transport system is established according to the actual conditions of urban public transport development after the implementation of the public transport priority development strategy. A number of complimentary indexes have been proposed additional to the established

index system, including public transport prioritized lane ratio, prioritized intersection ratio, harbor-type stop setting rate, and real-time incoming vehicle information forecast coverage,

as well as urban and rural passenger transport line transit-oriented operation rate. Finally, the fuzzy AHP combining the AHP and the fuzzy assessment is used to analyze the scientific legitimacy, rationality and serviceability of the assessment index system, and the assessment method based on a case study. 2. Establishment of Urban Public Transport Development Assessment Index System The full-scale implementation of the government initiated strategy of giving priority to urban public transport has given rise to a multitude of prominent characteristics of public transport in large and medium-sized Chinese cities: the acceleration of infrastructure construction, the continuous improvement of public transport service level, the acceleration of IT application, the increasing emphasis on sustainable development, the expanding policy support, and the significant social benefits. The establishment of a multitiered urban public transport development

level assessment index system in this paper is informed by the experiences in implementing the strategy of prioritizing urban public transport. Based on the principle Cilengitide of integrity, scientific legitimacy, comparability, conciseness, and practicality, the assessment index system consisted of a target layer, a criterion layer, and an index layer and evaluates the level of public transit development from six aspects, namely, infrastructure construction level, service level, IT development level, sustainable development level, government support level, and social benefit level (see Table 1). The assessment index system is described as follows. Table 1 Urban public transport development level assessment system and grading criteria. (1) Infrastructure Construction Level (U1).
