Study Of Urban Interchange Bridge Scheme Evaluation System

The urban interchange is an important component of the urban transport system, andplaying an important role in today's urban transport system. The Preparation and choice is thefirst step of the urban interchange scheme development and construction, as well as thefoundation of the follow-up work. Interchange scheme evaluation is a multi-goal, multi-criteriaevaluation, then how to give an objective Interchange scheme, scientific evaluation, it is adifficult matter.It introduced the actuality of the urban interchange project evaluation. And introducedthe urban interchange theory, laying the theoretical foundation for ~evaluation; Analyzed theevaluation methods which are relatively mature and contemporary popular both in the theoryand practice in the nowadays, chosen a mathematical method which is suit for the urbaninterchange evaluation: the fuzzy comprehensive evaluation method which is basis on theAnalytic Hierarchy Process (AHP) and fuzzy math, Expounded the evaluation implementationprocess, established a fuzzy mathematical model for evaluation, forming a feasiblemathematical methods.On the basis of the comprehensive study of the evaluation characteristic of interchangeschemes and referenced a large amount of domestic and foreign literature, take out theestablishing principle of the interchange scheme evaluation index system. Based on theprinciple, established the interchange scheme evaluation index system. Defined and analyzedthe evaluation indicators of the urban interchange scheme, take out the quantified methods ofthe evaluation indicators, educed a series of operational evaluation methods suit for the urbaninterchange scheme.Taking the Tuanjie Road Interchange of the Daqing city as an example, verified thecorrectness and feasibility of the method. It will give a useful reference for the future urbaninterchange scheme evaluation.
