The invention discloses a road safety message sending method and device. The method comprises the steps that the positional relation with a specific area is determined; the sending behavior of a road safety message is adjusted according to the positional relation with the specific area; the road safety message is sent when the positional relation with the specific area meets the preset conditions, and the road safety message is not sent anytime; or the sending parameters of the sent road safety message are changed when the positional relation with the specific area meets the preset conditions. Therefore, waste of communication resource can be reduced, and the possibility of sharp drop of communication quality between vehicle-vehicle, vehicle-road, vehicle-people and road-people caused by system congestion due to the fact that the road safety message is sent anytime can be reduced so that collaborative active safety warning performance can be guaranteed.
