Towards Intelligent Navigator That Can Provide Timely Advice on Safe and E cient Driving

This paper proposes a novel concept of intelligent navigator that can give the driver timely advice on safe and e cient driving. From both the current tra c condition obtained from sensory data and the driver's goal and preference in driving, it autonomously generates advice and gives it to the driver. Not only operational level advice, such as emergency braking due to an abrupt deceleration of the front vehicle, but also tactical level advice, such as lane changing due to the congested situation ahead, can be generated. Two main components of the intelligent navigator, the advice generation system and the road scene recognition system, are explained. On-line experiments using the prototype system show the potential feasibility of the proposed concept.
