Towards type-2 fuzzy rule base system for road choice

The road traffic becomes more complex to manage because of the high dynamics of traffic flow and the rise of travel time when the number of vehicles augments in the road networks. Hence, the shortest itinerary based on route length (as provided by GPS navigators) cannot be the best solution nowadays. The application of type-2 Fuzzy Logic is regarded as an effective way for transportation engineering to prevent the problem of ambiguity and uncertainty of road perceptions. In this paper, we propose a hierarchical type-2 Fuzzy Logic System to evaluate itinerary by integrating contextual factors influencing the route choice like speed and road work information.
