Abstract
In recent year, the number of traffic accidents caused by elderly drivers has increased. The effect of changes associated with aging in physical functions and cognitive functions is pointed out as one of the reasons. However, the car is one of important transportation for elderly. Therefore, the assistance measure to realize the safety driving for elderly drivers is needed. To overcome the problem, we are developing the agent that supports elderly drivers. The agent provides the advisement to elderly driver during driving a car and also encourages the driver to improve their driving behavior by showing their past driving records. In this paper, we described the analysis of human instructor's teaching model for considering the supporting method by the agent. From the analysis, we categorized the instructions into several groups and obtained findings about the impression of trainee caused by the instructions.
