This study presents a simulation approach employing a cognitive-perceptual model to discuss a train operators performance of obstacle detection on the rails of a Japanese high-speed railway. As its application, we specifically focused on a "Track Inspection Task" which is operated after completion of daily track maintenance operations with a special purpose tack maintenance train, i.e., so-called "Track Inspection Train". This model described a train operators perceptual and cognitive process during track monitoring. and inspection, and it allows us to simulate his behaviour as well as to track states during train operations. As input data to reproduce his visual function, the model required a train operators attention allocation patterns and eye-gaze distribution for each location, both of which were obtained by task observation in reality, as well as experimental data of the obstacle detection rates with eccentricity of visual field and its size. In the present paper, a great number of simulation runs were carried out to estimate the operators obstacle detection rates under various operating conditions, changing the size of an obstacle, its location on the track, driving speed, and so forth. Based on these simulation results, we discuss missing detection of obstacles that may cause a critical accident of the bullet train.
