• determining a criticality value for the ascertained change in the traffic information for each road section of the navigation map;
• determining a relevance value for the ascertained change in the traffic information for each road section of the navigation map;
• calculating a volume of change of the traffic information relating to the navigation map based at least in part on the ascertained changes in the traffic information, the determined criticality value, and the determined relevance value for all road sections of the navigation map;
• transmitting, from the server outside the vehicle to the vehicle, a response message comprising the traffic information for the navigation map of the vehicle if the calculated volume of change exceeds a predefined threshold value;
• and
• wherein the response message is configured such that the vehicle can update the traffic information relating to the vehicle based at least in part on the transmitted response message.
