To provide a submersion detection device, a submersion detection system, and a submersion detection program capable of detecting submersion easily without separately installing a submersion sensor in a vehicle.SOLUTION: A submersion detection device acquires rainfall data from a weather information center (100), acquires traffic data from a database and each vehicle (102), and determines as submersion an area where the traffic volume of vehicles is zero during or after rainfall and an area where the probability that the traffic volume of the vehicles in normal times will be zero is lower than a predetermined threshold value based on the rainfall data and the traffic data, assuming that the state where the amount of rainfall is less than the predetermined value is the normal time (104 to 110).SELECTED DRAWING: Figure 5
【課題】車両に冠水センサを別途設けることなく簡易に冠水を検知可能な冠水検知装置、冠水検知システム、及び冠水検知プログラムを提供することを目的とする。【解決手段】気象情報センタから降雨データを取得し(100)、交通量データをデータベース及び各車両から取得して(102)、降雨データ及び交通量データに基づいて、降雨時または降雨後に車両の交通量が0台の領域で、かつ降雨量が予め定めた値未満の状態を通常時として通常時の車両の交通量が0台となる確率が予め定めた閾値より低い領域を冠水と判定する(104〜110)。【選択図】図5
