A Study on the Priority Rating of Urban Roads for Improvement

Abstract

A new method for the identification of multiattribute utility functions is applied to the priority rating of urban roads for improvement. In the past research, Keeney.Raiffa’s method was used for this priority rating problem. However, this method has several weak points. So we applied a new method, by which multiattribute utility function is estimated from the comparison of road sections. By the new method, preferable utility functions were estimated with easy works of decision-maker.
