Abstract: A safe driving level evaluation device for evaluating a safe driving level of a driver, includes: a surrounding environment recognizing part for recognizing a surrounding environment of a vehicle; an ideal running route calculating part for calculating an ideal running route, including an ideal running position and an ideal running speed, based on the recognized surrounding environment; an actual running route detecting part for detecting an actual running route, including an actual running position and an actual running speed; an indicator value calculating part for calculating a safety indicator value so that it becomes a value indicating a safe driving level is lower when a difference between the ideal running route and the actual running route is large, compared to when it is small; and a safe driving level estimating part for estimating a safe driving level based on the safety indicator value calculated.
