Abstract
An apparatus for supplying traffic-related information in a vehicle receives a message concerning a traffic-related event, for instance a traffic queue. This message contains information about the location of the traffic-related event. The apparatus calculates the time and/or distance interval between the location of the event and the current position of the vehicle and gives an alarm if the time and/or distance interval is smaller than a predetermined time and/or distance interval.
