1. A driving support device which is mounted on an own vehicle, the driving support device comprising:
a memory storing one or more instructions; and
a processor operatively connected to the memory and configured to execute the one or more instructions stored in the memory, wherein the one or more instructions, when executed by the processor, cause the driving support device to:
control a drive device and a braking device of the own vehicle such that a speed of the own vehicle matches a predetermined first target value when another vehicle is not present in front of the own vehicle;
recognize a signal color of a traffic light present in a predetermined area extending in front from the own vehicle;
detect a position of the own vehicle and a position of the traffic light,
wherein the signal color of the traffic light is recognizable when a distance to the traffic light positioned in front of the own vehicle is equal to or shorter than a first predetermined value;
control the drive device and the braking device of the own vehicle before a first point such that a speed of the own vehicle at a time at which the own vehicle reaches the first point is equal to or lower than a second target value which is a lower speed than the predetermined first target value, the first point being a point at which a distance to a first traffic light, which is the nearest traffic light positioned in front of the own vehicle, is the first predetermined value; and
control the drive device and the braking device such that, when a signal color of the first traffic light that is recognized is green, and a distance between the first traffic light and a second traffic light that is positioned ahead of the first traffic light is equal to or shorter than a predetermined threshold value, wherein the second traffic light is further away from the own vehicle than the first traffic light, the own vehicle travels at a constant speed equal to or lower than the second target value until a signal color of the second traffic light is recognized.
