Route Recommendation Method Based on Driver’s Intention Estimation Considering the Route Selection When Using the Car Navigation

Nowadays, car navigation systems are widely used for providing directions to drivers’ destination. However, they do not always recommend a route that perfectly matches the driver’s intent. Even when drivers intentionally change the driving route from the recommended one to another, most of car navigation systems lead them back to the original recommended route. Such recommendations may not adequately reflect the driver’s intent. Therefore, in our previous work, we have proposed a route recommendation method based on estimating driver’s intent by comparing the characteristics of the route selected by driver and the route not selected by driver but recommended by car navigation system. However, the method could take into account only one kind of traveling cost of each road. Thus, in this paper, we propose a method that can consider multiple costs and learn drivers’ concept of values for each cost.
