Correlation between functional depreciation with age and driver's behavior in emergency

The traffic accidents have been increasing every year, and the accident ratio of elderly people is larger than the others. One of the reasons is the depreciation of physical capability of elderly people. In this research, the driver's behavior is measured by the driving simulator which has the sensors attached to the steering, accelerator and brake. Moreover, we measure the fundamental characteristics related to the cognition, judgment and movement of a driver. From the investigation of each correlation, it is shown clearly how the depreciation of cognition, judgment and movement functions influenced the traffic accidents.
