To provide a seismic intensity estimation device capable of accurately estimating the seismic intensity at a vehicle position even when the vehicle is not on the surface of the earth itself but located on a structure that exists on the surface of the earth.SOLUTION: A seismic intensity estimation unit 22 is configured to receive earthquake information indicating the occurrence and scale of earthquakes and estimates the ground seismic intensity at the current location of the vehicle based on ground characteristics information representing ground characteristics at the current position of the vehicle and the earthquake information. When the vehicle is on an elevated road, bridge, etc., the seismic intensity estimation unit 22, estimates the seismic intensity at the position of the vehicle on the structure based on seismic intensity on the surface and the vibration characteristics of the structure. An output unit 24 transmits the estimated seismic intensity information indicating the estimated earthquake intensity to vehicles and a vehicle operation system and the like.SELECTED DRAWING: Figure 4
【課題】車両が地表そのものの上に存在せずに、地表上に存在する構造物上に存在する場合であっても、その車両の位置の震度を精度良く推定すること。【解決手段】震度推定部22は、地震の発生と規模とを示す地震情報を受け付け、車両の現在の位置における地盤特性を示す地盤特性情報と地震情報とに基づいて、車両の現在の位置における地表の震度を推定する。車両が高架や橋梁等の構造物上に存在する場合、震度推定部22は、地表の震度と当該構造物の振動特性とに基づいて、当該構造物上に存在する車両の位置の震度を推定する。出力部24は、その推定された震度を示す推定震度情報を、車両や車両運行システム等に送信する。【選択図】図4
