The study of driver’s brain activity and behaviour on DS test using fNIRS

In this study, according to Driving Simulator test, based on brain activity measuring using fNIRS, we tried to grasp the interaction between a driver’s reaction on sighting Variable Message Sign, and a driver’s behavior, such as the change of car speed and acceleration. As the result, we confirmed that Parietal association cortex and Prefrontal area activated in the case of a driver’s driving with recognition and judgment using the collecting information from an environment. Therefore, it was suggested that it needs to expand the measuring area to Parietal association cortex in the case of evaluating driver’s activity.
