Developing A Priority-Based Decision Making Mod To Evaluate Geometric Configuration of Urban Interchanges

The present article involves in evaluation and engineering judgment of various geometric configurationsfor highway interchanges by considering substantial parameters over the discretionprocess. the geometric, economical and architectural criteria as the fundamental indicators are dividedinto related sub-indicators and the total combinations of such sub-elements from the generalcriterion for establishment of decision making process. hence, this article deals with geometricconfiguration analysis of interchanges as a complex decision problem by the use of analytic hierarchyprocess (ahp) which is a structured technique to analyze complicated engineering systems.by considering an interchange as a case study in north of tehran, the capital of iran, the performanceof the proposed method has been examined in order to select the most suitable type ofinterchange by forming the evaluation process of ahp and taking into account the given designand construction data. a wide range of notorious criteria and desired prerequisites are available.owing to established the ahp model and perform the decision-making method, the expert choiceanalytical software has been utilized. the evaluation results are determined in terms of prioritiesfor various options and their decision weights in the case study. however the presented model isable to be applied for other cases and different alternatives. as a tentative finding, using directionalpattern for the case example of current work has been the optimum variant rather than parallelalternatives i.e. semi-directional and loop schemes.
