Abstract
The railway accidents caused by human errors don't disappear at present. Decline of the train driver's arousal level has the possibility to cause it. The new type of operation support system to retain the arousal level should be necessary. We developed a new type of train simulator to analyze the human behavior of train driver. Outline of simulator is described in this paper. Experiments to measure the driver's cerebral blood flow are carried out by using the developed train simulator. It is shown that the simulator is effective for obtaining driver's brain activity.
