Abstract

A method for route guidance of a user includes steps of transmitting a first item of information with respect to a planned journey from an instantaneous position to a destination position from the user to a central authority, determining, by way of the central authority, a traffic situation in an area of a route from the instantaneous position to the destination position, and transmitting a second item of information, which provides information about the traffic situation, from the central authority to the user.

Claims

1. A computer-implemented route guidance method comprising:

obtaining, by a computer processor of a central processing device and from a user device, a first item of information with respect to a planned journey from an instantaneous position to a destination position;

determining, by the processor, a traffic situation in an area of a first route from the instantaneous position to the destination position;

transmitting, by the processor and to the user device, a second item of information, the second item of information being based on the determined traffic situation.

2. The method of claim 1, wherein the first item of information includes the instantaneous position and the destination position, the first route is determined by the processor, and the second item of information includes the first route.

3. The method of claim 1, wherein the first item of information includes the first route.

4. The method of claim 1, wherein the second item of information includes a modified route that differs from the first route based on the traffic situation.

5. The method of claim 1, wherein the processor is configured to:

receive the first item of information from each of a plurality of user devices, each of the first items of information being with respect to a respective planned journey from a respective instantaneous position to a respective destination position; and

control a device for influencing a traffic flow based on the first items of information from the plurality of user devices.

6. The method of claim 1, wherein the processor is configured to:

receive the first item of information from each of a plurality of user devices, each of the first items of information being with respect to a respective planned journey from a respective instantaneous position to a respective destination position; and

determine the second item of information for each of the user devices based on the first items of information from the plurality of user devices, the second items of information varying for different ones of the user devices to equalize a distribution of routing of the user onto different routes.

7. The method of claim 1, wherein a unique identifier is assigned to the user device and the identifier is obtained by the processor together with the first item of information.

8. The method of claim 1, wherein the traffic situation is determined based on historic traffic data.

9. The method of claim 1, wherein the traffic situation is determined based on data of a traffic monitoring system.

10. The method of claim 1, wherein the second item of information is transmitted from the user device to another user device.

11. The method of claim 1, wherein the user device is a component of a first vehicle.

12. The method of claim 11, wherein the second item of information is transmitted from the user device to another user which is a component of a second vehicle.

13. The method of claim 1, wherein the user device is a component of a first vehicle, the processor is accessible by the user device and by user devices that are respective components of other respective vehicles.

14. The method of claim 13, wherein the second item of information is based on respective route related information of the first vehicle and of the other respective vehicles.

15. A non-transitory computer-readable medium on which are stored instructions executable by a processor, the instructions which, when executed by the processor, cause the processor to perform a route guidance method, the method comprising:

obtaining from a user device a first item of information with respect to a planned journey from an instantaneous position to a destination position;

determining a traffic situation in an area of a first route from the instantaneous position to the destination position; and

transmitting to the user device a second item of information, the second item of information being based on the determined traffic situation.
