Method for supplying a signal for at least one vehicle

A device for supplying a signal for at least one vehicle, comprising:

• a traffic-density detection system to detect a traffic density at an exit point of a traffic node;
• and
• a first arrangement by which a signal is supplied as a function of the traffic density at the exit point of the traffic node;
• wherein data values that are representative of at least one trajectory of at least one further vehicle are called up from an external data source, the at least one trajectory of the further vehicle connecting a further entry point of the further vehicle into the traffic node to a further exit point of the further vehicle from the traffic node, and the signal being generated as a function of the trajectory of the further vehicle.

A non-transitory computer-readable storage medium on which is stored a computer program, which is executable by a processor, comprising:

• a program code arrangement having program code for supplying a signal for at least one vehicle that is located in front of an entry point into a traffic node, by performing the following:
• detecting a traffic density at an exit point of the traffic node;
• and
• supplying a signal as a function of the traffic density at the exit point of the traffic node;
• wherein data values that are representative of at least one trajectory of at least one further vehicle are called up from an external data source, the at least one trajectory of the further vehicle connecting a further entry point of the further vehicle into the traffic node to a further exit point of the further vehicle from the traffic node, and the signal being generated as a function of the trajectory of the further vehicle.
