Abstract

A method for supplying a signal for at least one vehicle that is located in front of an entry point into a traffic node, it is provided that the method includes a step of detecting a traffic density at an exit point of the traffic node, as well as a step of supplying a signal as a function of the traffic density at an exit point of the traffic node.

Claims

1. A method for supplying a signal for at least one vehicle that is located in front of an entry point into a traffic node, the method comprising:

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.

2. The method as recited in claim 1, wherein the vehicle at least one of:

(i) enters the traffic node as a function of the signal, (ii) decelerates in an area of an entry point into the traffic node, and (iii) comes to a standstill in the area of the entry point of the traffic node.

3. The method as recited in claim 1, 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.

4. The method as recited in claim 3, wherein the traffic density at the exit point is detected as a function of the at least one trajectory of the at least one further vehicle.

5. The method as recited in claim 3, wherein a further traffic density at the further exit point from the traffic node of the further vehicle is detected and the signal is detected as a function of the further traffic density.

6. The method as recited in claim 3, wherein, due to the signal, a further signal is transmitted to the further vehicle, which informs the further vehicle whether the vehicle at least one of:

(i) enters the traffic node, (ii) decelerates in an area of the entry point of the traffic node, or (iii) comes to a standstill in the area of the entry point of the traffic node.

7. The method as recited in claim 3, wherein the vehicle is operated as a function of the supplied signal, and a decision as to whether the vehicle enters the traffic node is made on the basis of the supplied signal.

8. The method as recited in claim 1, wherein the supply of the signal takes place in such a way that the signal is output to at least one operator of the vehicle, the output taking place in at least one of:

(i) an optical manner, (ii) an acoustic manner, and (iii) a haptic manner.

9. The method as recited in claim 1, wherein the traffic node is a traffic circle.

10. 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.

11. A non-transitory computer-readable storage medium on which is stored a computer program for supplying a signal for at least one vehicle that is located in front of an entry point into a traffic node, the computer program, when executed by a processor, causing the processor to perform:

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.
