Abstract
Methods for detecting any unusual conditions affecting a driver, based on driving behavior, are proposed in this paper. This study analyses driving behavior of train drivers using a train driving simulator that simulates train operation. We focus on braking behavior when approaching a station. The method of detecting unusual braking operation is examined by giving drivers mental calculation problems as a mental workload. The variance of the brake-handle operation was significantly larger when a mental workload was imposed, indicating the possibility of determining the driving characteristics of individuals. We examined the possibility of detecting unusual driving by evaluating the deceleration trajectory.
