AUTOMATED DRIVING VEHICLE AND TRAFFIC SAFETY SUPPORT SYSTEM

An automated driving vehicle includes: an external information acquisition device configured to acquire external information regarding a state of surroundings of the automated driving vehicle as a vehicle of interest; an on-board communication device configured to receive a risk area notification regarding a high-risk area in a target traffic area ; an action plan formulation device configured to formulate 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 control device configured to operate a travel actuator based on the action plan to cause the vehicle of interest to automatically travel. In a case where the vehicle of interest is moving within the high-risk area, the action plan formulation device sets the behavior allowable range to a range associated with the risk area notification.
