Route recommendation method for car navigation system based on estimation of driver´s intent

Nowadays, car navigation systems are widely used in cars to aid drivers by providing directions to a destination. However, these systems do not always recommend a route that perfectly matches the driver´s intent. Even when drivers intentionally select a route that is different from the recommended one, the system leads them back to the original route. Such recommendations do not adequately reflect the driver´s intent. This study proposes a route recommendation method for a car navigation system that estimates the driver´s intent and rerecommends a route that matches this intent when the driver deviates from the originally recommended route. We developed a simulator based on the proposed method and used it to experimentally verify the effectiveness of the proposed method.
