In this paper, disaggregate behavioral model using fuzzy integral utility function is proposed. The purpose of the modeling is to represent the mechanism that driver evaluates the alternatives by using offered information and his own perception to the traffic situation, in case of route choice behavior. This is based on the traffic information system, one of the ITS policies. As a result, it is possible to estimate efficient parameters that satisfy the sign conditions by using fuzzy integral utility functions, in case that each attribute to use for the evaluation of the altenatives is not independent mutually and that weight parameter of the attribute does not have finite additivity. Therefore, it is known that this model is efficient to analyze drivers' behavior in case that traffic information is offered to plural attributes.
