Abstract: In the vehicle traveling control device, a host vehicle location specification unit specifies a host vehicle location on a map. A first peripheral information detector detects a location of a planimetric feature or characteristics of a road in a periphery of the host vehicle on the basis of map data and the host vehicle location on the map specified by the host vehicle location specification unit. A second peripheral information detector detects a location of a planimetric feature or characteristics of a road in the periphery of the host vehicle on the basis of information acquired by a camera, a sensor, or a road-vehicle communication device mounted on the host vehicle. When the detection result from the first peripheral information detector and the detection result from the second peripheral information detector do not coincide, an automatic driving restriction unit restricts performance of automatic driving of the host vehicle.
