To provide a traffic road change determination device that can accurately determine a vehicle's right/left turn at an intersection and, by extension, accurately determine a change in a road on which a vehicle passes.SOLUTION: A situation of a vehicle speed adjustment operation for adjusting the vehicle speed is detected, and first, an entry of the vehicle into an intersection is determined based on the detected situation (S6). When it is determined that the vehicle enters the intersection, then it is determined that the vehicle turns right or left (turn right or left) at the intersection where the vehicle entered, based on a behavior of the vehicle (S7). That is, the entry of the vehicle into the intersection is determined before the determination of the right/left turn of the vehicle at the intersection, and if the vehicle has not entered the intersection, the determination of the right/left turn of the vehicle is not performed.SELECTED DRAWING: Figure 2
【課題】交差点での車両の右左折を精度よく判定でき、ひいては車両が通行する道路の変更を精度よく判定できる、通行道路変更判定装置を提供する。【解決手段】車速を調節する車速調節操作の状況が検出され、まず、その検出された状況に基づいて、車両の交差点への進入が判定される(S6)。交差点への車両の進入が判定された場合、次に、車両の挙動に基づいて、その車両が進入した交差点での車両の右折または左折(右左折)が判定される(S7)。つまり、交差点での車両の右左折の判定前に、その交差点への車両の進入が判定され、車両が交差点に進入していない場合には、車両の右左折の判定が行われない。【選択図】図2
