The lane monitoring unit 370 functions to store and manage lane departure information from the lane departure device, camera device, and turn signal device installed in the vehicle. Lane departure information is determined by combining camera images installed on the vehicle, lane departure device, and turn signal information. For example, the lane monitoring unit 370 determines the lane through a camera image recording the front of the vehicle, and if the lane is a solid line, when a bus changes lanes, it collects lane departure information. In addition, when the lane is a dotted line, it is determined whether the bus vehicle left the lane after the turn signal is turned on. Even if the turn signal is not turned on and the bus vehicle deviates from the lane, this is collected as lane departure information, but after the turn signal is turned on, the bus vehicle deviates from the lane. If a bus vehicle deviates from its lane, it is judged to be a normal lane change and this is not collected as lane departure information. Camera footage when leaving the lane is recorded along with turn signal information and transmitted to the server. Through these lane departure statistics, managers can take appropriate measures, such as selecting those eligible for safe driving training and providing training by risk level.
