Abstract (en)
A railroad vehicle operation control apparatus according to an embodiment includes a sensor configured to detect an obstacle in a traveling direction of a railroad vehicle in traveling, a maximum detection distance calculation module configured to calculate a maximum detection distance within which the sensor is able to detect the obstacle, a stopping distance calculation module configured to calculate a stopping distance when an emergency brake of the railroad vehicle is applied, a temporary speed limit calculation module configured to calculate a temporary speed limit that is a vehicle speed at which the railroad vehicle is able to stop by the emergency brake at the smaller distance of the maximum detection distance and the stopping distance, a regular speed limit calculation module configured to calculate a regular speed limit corresponding to a position of the railroad vehicle during normal traveling, a traveling pattern setting module configured to calculate and set a traveling pattern representing relationship between the position and a target speed of the railroad vehicle based on the temporary speed limit and the regular speed limit, and a target speed generation module configured to generate the target speed based on the traveling pattern and transmit the target speed to a control device of the railroad vehicle.
