We have developed a new system which quantifies elderly driver's potential function for driving based on characteristics of dementia and which judge they are able to drive or not. First, to clarify the operating characteristic of this system, an experiment was adopted in a study on 104 elderly drivers. And the result of the experiment was qualitatively classified and operating characteristics was extracted. Next, to extract unsafe driving act, the experiment with a driving simulator was conducted for 19 elderly drivers. To compare these two experiments, some operating characteristics related to unsafe driving act was decided. In addition, the operating characteristics were compared with the result of a medical index and the real car running.
