Abstract: A flood detection device and method that acquires meteorological data; acquires traffic volume data representing vehicle traffic volume; and determines that an area, in which a vehicle traffic volume during or after rain is less than or equal to a predetermined number of vehicles, is flooded based on the meteorological data and the traffic volume data, when a probability, that the vehicle traffic volume in a normal time is less than or equal to the predetermined number of vehicles, is less than a predetermined value, the normal time being a state in which a rainfall amount is less than a predetermined value.

Abstract: A flood display device includes: a processor with hardware, the processor being provided to: acquire flood point information in which a detection result of a flood point of a road and a classification of a flood situation at the flood point determined based on traveling state data of a vehicle traveling at the detected flood point are associated with each other based on the traveling state data related to the traveling of the vehicle, generate flood detection information in which a display mode of the detection result is changed based on the classification of the flood situation as flood detection information obtained by superimposing the detection result on a position on a map corresponding to the flood point based on the flood point information, and output the flood detection information to a display.

Abstract: A flooding sensing device, including: an acquisition section configured to acquire vehicle model information and plural items of travel state data related to travel of a vehicle; and a detection section configured to select a vehicle behavior model from plural vehicle behavior models that are derived in advance for each vehicle model, the vehicle behavior model corresponding to the vehicle model information and calculates a physical quantity that changes in accordance with travel by the vehicle, the detection section detects flooding of a road on which the vehicle travels, using the physical quantity, which is predicted based on the selected vehicle behavior model and on the current plurality of items of travel state data acquired by the acquisition section, and using the physical quantity, which is obtained from the current plurality of items of travel state data acquired by the acquisition section.
