Abstract: In at least some embodiments of the present disclosure, an emergency situation notification device installed in a vehicle transmits a message for notifying an occurrence of an emergency situation of the vehicle when the emergency situation occurs, and an emergency situation display device installed in a street light performs a turning-on operation or a blinking operation according to reception of the message for notifying the occurrence of the emergency situation. Further, when a message notifying that an emergency vehicle is currently being dispatched is received from an emergency situation notification device which may be installed in the emergency vehicle, etc., a control center server controls emergency situation display devices, which are installed in street lights in the proceeding direction of the vehicle currently being dispatched, to properly generate warning signs.
