TRAFFIC SAFETY SUPPORT SYSTEM

Provided is a traffic safety support system capable of improving traffic safety in a situation in which it is predicted that a mobile body other than a host vehicle is shielded by a nearby vehicle present near the mobile body. A traffic safety support system includes a recognizer, a HMI, a risk notification setting unit, and a risk notification control device. The risk notification setting unit sets a notification mode to a hinting notification mode in a case where a motorcycle acts as an oncoming mobile body, and where a four-wheeled automobile is present near the motorcycle and is approaching a four-wheeled automobile from the front in the traveling direction of the four-wheeled automobile, and sets the notification mode to an analogue notification mode in a case where the motorcycle is present within an analogue notification range.
