Abstract
We proposed a method to evaluate the degree of safe driving based on a cognitive test utilizing the Trail Making Test-J Part B (TMT-J) and a minimum TTC using a driving simulator. We also proposed a training program to acquire compensatory behavior through metacognition. The effectiveness of these methods was tested on 30 elderly drivers. It was confirmed that a combination of TMT-J and driving ability was effective in judging safe driving. In addition, the use of charts comparing driving ability with others and a bird's-eye view of driving improved metacognitive abilities and realized compensatory behaviors for safe driving.
