DRIVING SUPPORT DEVICE, DRIVING SUPPORT METHOD, AND DRIVING SUPPORT PROGRAM

A driving support device () includes a signal color recognition device and a speed control device. The speed control device controls a drive device () and a braking device () of an own vehicle before a recognizable point (Pr) such that a vehicle speed (Vs) at a time at which the own vehicle reaches the recognizable point (Pr) is equal to or lower than a target value (V) which is a lower speed than a target value (Vd). The recognizable point (Pr) is a point at which a distance to the nearest traffic light (S) positioned in front of the own vehicle is a predetermined value (Lr). The speed control device also controls the drive device () and the braking device () such that, when the signal color recognition device recognizes a signal color of the traffic light (S), the signal color is green, and a distance (DS) between the traffic light (S) and a traffic light (S) next in front from the traffic light (S) is equal to or shorter than a predetermined threshold value (DSth), the own vehicle travels at a constant speed equal to or lower than the target value (V) until the signal color recognition device recognizes a signal color of the traffic light (S).
