To provide a proper speed arithmetic device capable of determining a proper speed dependent on an environment in which there is a curve of a road.SOLUTION: A proper speed arithmetic device 10 includes a vehicle information acquisition unit 1 that acquires information on the position and advancing direction of a vehicle, a road information acquisition unit 2 that acquires information on a road being present ahead in the advancing direction of the vehicle, a curve detection unit 3 that detects a curve from the road ahead in the advancing direction of the vehicle, and a proper speed arithmetic unit 4 that calculates a proper speed at the curve on the basis of the shape of the curve. The proper speed arithmetic device 10 further includes a deceleration adequateness decision unit 5 that decides on the deceleration adequateness at the curve on the basis of the environment in which there is the curve, and a proper speed modification unit 6 that modifies the proper speed, which is calculated based on the shape of the curve, on the basis of the deceleration adequateness at the curve.SELECTED DRAWING: Figure 1
