PROBLEM TO BE SOLVED: To provide a curve-estimating apparatus capable of accurately determining the curvature/diameter of a curve in a track ahead of one's own vehicle, even in a track in which the curvature/diameter of a curve continuously change, and to provide a travel control apparatus using the same. SOLUTION: By comparing the actual distance to a vehicle traveling ahead measured by a laser radar 14 with a target distance between vehicles, based on the setting of an operating switch 15 (taking into consideration the vehicle speed detected by a vehicle speed sensor 11) and determining the weighted mean of the diameter of curve at the location of one's own vehicle, determined on the basis of output of a yaw rate sensor 12 and a steering angle sensor 13 and the diameter of a curve at the location of the vehicle traveling ahead determined by a white line recognizing ECU 2 by image recognition processing, on the basis of an image acquired by a front camera 21 by a weighting factor set, according to the distance between vehicles, the diameter of the curve in a track ahead of one's own vehicle is estimated.
