A method for predictively estimating the transmission conditions for a communication between two communication partners traveling along a roadway, wherein the communication partners themselves estimate the current transmission conditions. The communication partners use the estimated transmission conditions of a number of preceding communication partners to better estimate the transmission conditions for a future time. The communication partners themselves also estimate the transmission conditions for the future time based on a sensor-based detection of the surroundings and merging the estimation results obtained in this way with the results obtained from the preceding transportation vehicles.
