The study of driver's reaction for traffic information on actual driving and DS using fNIRS

Abstract

Central Nippon Expressway Company limited has been investigated the more effective evaluation method for traffic safety measures using fNIRS and DS in order to consider the improvement plan of traffic safety measures from now on. Because the fact that it is impossible to avoid the occurrence of a variety of biases has remained an issue to be solved by this method. However, the actual road test has much difficulty to measure a driver's reaction and to ensure safety. Then we reevaluated the effectiveness of DS test in the neuroscience aspect. In this study, we measured the driver's reaction by the brain activity related with “recognition” and “judgment” out of 3 elements of driving for the traffic information on the actual driving and in the DS. As a result of analyzing driver's reaction on the actual driving and in the DS, we could confirm the similarity part of drivers' reaction. Then we could confirm that it was suitable to the evaluation of traffic safety measures by the DS test.
