The method includes obtaining information relating to a driving intention based on the intention to carry out the driving maneuver, determining a position of the transportation vehicle, determining the driving intention message based on the information relating to the driving intention, and calculating transmission parameters for the driving intention message. The transmission parameters include a repetition rate and a transmission time, and the calculation is based on a desired probability of receipt of the driving intention message, the driving intention, and the position of the transportation vehicle.
