(EN) According to the present invention, state information indicating a state of a vehicle is received from the vehicle, and the presence of a first vehicle entering an intersection and a second vehicle entering the intersection from a direction opposite that of the first vehicle is recognized on the basis of the received state information. On the basis of the state information, a determination is made that the first vehicle is advancing straight and that the second vehicle is turning in a direction that cuts across an oncoming lane. If it has been determined that the first vehicle is advancing straight and the second vehicle is turning in a direction that cuts across the oncoming lane, then the first vehicle and/or the second vehicle is alerted to the possibility of coming close to another vehicle. The determination involves determining, on the basis of the state information received from the first vehicle, that the first vehicle is advancing straight if it has been determined that a turn signal is not operating or that turning-off the turn signal was forgotten.
(ZH) 根据本发明，从车辆接收表示该车辆的状态的状态信息，基于接收到的状态信息，识别进入交叉路口的第一车辆和从与第一车辆对向的方向进入交叉路口的第二车辆的存在。并且，基于状态信息，判定为第一车辆直行且第二车辆向横穿对向车道的方向转弯，在判定为第一车辆直行且第二车辆向横穿对向车道的方向转弯的情况下，向第一车辆和第二车辆中的至少一方报告与其他车辆接近的可能性。在判定中，在基于从第一车辆接收到的状态信息而判定为方向指示器未工作、或者方向指示器忘记关闭的情况下，判定为第一车辆直行。
