To provide a safe driving level evaluation device for evaluating a safe driving level of a driver by a new method.SOLUTION: A safe driving level evaluation device for evaluating a safe driving level of a driver comprises: a peripheral environment recognition section 331 for recognizing a peripheral environment of a vehicle; an ideal travel route calculation section 332 for calculating an ideal travel route of the vehicle including an ideal travel position and ideal travel speed of the vehicle based on the recognized peripheral environment; an actual travel route detection section 333 for detecting an actual travel route of the vehicle including the actual travel position and actual travel speed of the vehicle; an index value calculation section 334 for calculating a safety index value to be the value which expresses that the safe driving level is lower when a difference between the ideal travel route and the actual travel route is larger compared with a case with a smaller difference; and a safe driving level estimation section 335 for estimating a safe driving level based on the calculated safety index value.SELECTED DRAWING: Figure 7 【課題】ドライバの安全運転レベルを新たな手法で評価する安全運転レベル評価装置を提供する。【解決手段】ドライバの安全運転レベルを評価する安全運転レベル評価装置は、車両の周辺環境を認識する周辺環境認識部３３１と、認識された周辺環境に基づいて車両の理想的な走行位置及び理想的な走行速度を含む、車両の理想走行経路を算出する理想走行経路算出部３３２と、車両の実際の走行位置及び実際の走行速度を含む、車両の実走行経路を検出する実走行経路検出部３３３と、理想走行経路と実走行経路との差が大きい場合には小さい場合に比べて安全運転レベルが低いことを表す値になるように安全性指標値を算出する指標値算出部３３４と、算出された安全性指標値に基づいて安全運転レベルを推定する安全運転レベル推定部３３５とを備える。【選択図】図７
