Multi-stage fuzzy reasoning is used to describe the driver decision making process on road networks. Their term paper considers the multi-route choice problem. The first step for multi route choice is made a survey and collected data. Experiment participants were asked about the number of alternative routes they use going from their origin to their destination (the authors asked the respondents to city at most three alternatives they may use). For each route considered they defined its characterizing factors (travel time, degree of congestion and risk of accidents). All the participants estimated the values of all the factors using their own perception and experience. Appropriate fuzzy numbers could then represent these values. The third survey question dealt with the values of the utilities of the nominated routes. The authors assumed the existence of two stages in the driver decision making process. The first approximate reasoning algorithm they proposed determined the utilities of the alternative routes
