1. A traffic safety support system comprising:
an external information acquirer configured to acquire external information regarding a state of surroundings of the automated driving vehicle as a vehicle of interest;
an information provider connected to the vehicle of interest via wireless communication;
an on-board communicator configured to receive a risk area notification regarding a high-risk area in a target traffic area, the risk area notification being wirelessly transmitted from an the information provider;
an action plan formulator configured to formulate, based on the external information and the risk area notification, an action plan for the vehicle of interest such that a behavior of the vehicle of interest is prevented from exceeding a predetermined behavior allowable range; and
a travel controller configured to operate a travel actuator based on the action plan to cause the vehicle of interest to automatically travel, wherein
the information provider comprising:
a target traffic area recognizer configured to recognize, as recognition targets, traffic participants in the target traffic area and traffic environments surrounding the traffic participants, and acquire recognition information regarding the recognition targets, and
a high-risk area identifier configured to identify the high-risk area in the target traffic area based on the recognition information,
in a case where the vehicle of interest is moving within the high-risk area, the action plan formulator sets the behavior allowable range to a range associated with the risk area notification, and
the high-risk area identifier identifies a local traffic area in the target traffic area where a traffic volume calculated based on the recognition information deviates from a predetermined standard traffic volume by a predetermined value or more as the high-risk area.
