  The recent reform of the 5.9 GHz by the United States Federal Communications
Commission (FCC) provoked the need for lightening the load of a
vehicle-to-everything (V2X) communications network based on Dedicated Short
Range Communications (DSRC). We have collected mathematical analyses and
numerical results supporting our proposal of lightening a DSRC network by
prioritizing the transmission based on the risk of accident to which a vehicle
is exposed.
