A Proposal of Dynamic Route Search Method to Consider the Individual Driver Preferences

In this study, we are aiming to the Dynamic Route Search method which satisfies the preferences of individual drivers. The preferences here mainly relate to the route search and depend on individual driver. During the route search, there are various elements of preference, such as "Road width", "Travel time" or "Traffic jam" and so on. The preference is fuzzy, because human subjectivity and intuition. Especially when considering the multiple elements, to reflect the fuzziness and the interaction between the elements, we use the Fuzzy Analytic Hierarchy Process (Fuzzy-AHP) to integrate them into the Route Search cost. However, the dynamic elements like traffic jam or accident often occurs on the way, so a new replanning is necessary. For improving the efficiency of replanning, we proposed a Dynamic Route Search method based on D-star algorithm.
