Outline of Final Research Achievements

In this research, new route guidance techniques were developed and new digital road map was proposed.
One of the developed techniques is for determination of optimum lane change instruction timing. The optimal timing is estimated by mathematical model using the information of target vehicle position and the traffic flow rates for each lane. The developed technique was verified through the traffic simulation analysis.
In addition, the new digital road map expressed by mesh divided road space was proposed. The road characteristics and traffic states are stored in each mesh and used for lane-level navigation. Through the field experiments, its validity was verified.
