Abstract

A method is described for detecting a wrong-way driving incident of a motor vehicle on a unidirectional roadway, using a traffic monitoring device. A motor vehicle is recognized by the traffic monitoring device, a moving direction of the motor vehicle is determined based on data of the traffic monitoring device, and a wrong-way driving incident is detected when a moving direction is against a direction of traffic of the unidirectional roadway. A traffic monitoring device for detecting a wrong-way driving incident of a motor vehicle on a unidirectional roadway is provided, which includes a recognizing arrangement to recognize a motor vehicle, a determining arrangement to determine a moving direction of the motor vehicle based on data of the traffic monitoring device, and a detecting arrangement to detect a wrong-way driving incident when a moving direction is against a direction of traffic of the unidirectional roadway.

First claim

What is claimed is:

1. A method for detecting a wrong-way driving incident of a motor vehicle on a unidirectional roadway, using a traffic monitoring device, the method comprising:
setting a detection direction of the traffic monitoring device to at least one of: face toward oncoming traffic, or face toward receding traffic;
recognizing the motor vehicle by the traffic monitoring device;
determining a moving direction of the motor vehicle based on recognition in an image by the traffic monitoring device at least one of: a front side of the motor vehicle, or a rear side of the motor vehicle; and
detecting the wrong-way driving incident when the moving direction is against a direction of traffic of the unidirectional roadway.

2. The method of claim 1 , wherein the moving direction is determined at least based on image recognition of the front side of the motor vehicle facing the traffic monitoring device.

3. The method of claim 2 , wherein the traffic monitoring device faces in a direction opposite the direction of traffic of the unidirectional roadway, and the wrong-way driving incident is detected when the front side of the motor vehicle is recognized.

4. The method of claim 2 , wherein the traffic monitoring device faces in a same direction as the direction of traffic of the unidirectional roadway, and the wrong-way driving incident is detected when the rear side of the motor vehicle is recognized.

5. The method of claim 1 , wherein the moving direction is determined by comparing at least two images of the motor vehicle recorded by the traffic monitoring device.

6. The method of claim 1 , wherein the moving direction is determined with an aid of communication between a transmitter unit and/or receiver unit of the motor vehicle and a transmitter unit and/or receiver unit of the traffic monitoring device.

7. The method of claim 1 , wherein the traffic monitoring device includes a toll device, a traffic camera, and/or induction strips provided in the unidirectional roadway.

8. The method of claim 1 , wherein a warning is output to other road users after a wrong-way driving incident is detected.

9. The method of claim 8 , wherein the warning includes the activation of optical warnings and/or a wirelessly transmitted message to the motor vehicle and/or to other road users.

10. The method of claim 1 , wherein a lane of the unidirectional roadway is determined in which a motor vehicle is situated driving the wrong-way.

11. The method of claim 1 , wherein the moving direction is determined at least based on image recognition of the rear side of the motor vehicle facing the traffic monitoring device.

12. The method of claim 1 , wherein the moving direction is determined by recognition of the front side or rear side of the motor vehicle in a single image.

13. The method of claim 1 , wherein the moving direction is determined based on a at least one factor in addition to the recognition of the front side or rear side of the motor vehicle.

14. The method of claim 13 , wherein the at least one factor includes at least one of: a determination based on comparing at least two images of the motor vehicle recorded by the traffic monitoring device, or a determination based on communication between a transmitter unit and/or receiver unit of the motor vehicle and a transmitter unit and/or receiver unit of the traffic monitoring device.

15. The method of claim 13 , wherein the at least one factor provides a plausibility check of the determination based on the recognition of the front side or rear side of the motor vehicle.

16. The method of claim 1 , further comprising, in response to detecting the wrong-way driving incident, outputting a warning to a driver of the motor vehicle.

17. The method of claim 1 , further comprising, in response to detecting the wrong-way driving incident, generating an intervention in at least one of: a movement of the motor vehicle, or a steering of the motor vehicle.

18. A traffic monitoring device for detecting a wrong-way driving incident of a motor vehicle on a unidirectional roadway, the traffic monitoring device comprising:
a detection direction arrangement to set a detection direction of the traffic monitoring device to at least one of: face toward oncoming traffic, or face toward receding traffic;
a recognizing arrangement to recognize the motor vehicle;
a determining arrangement to determine a moving direction of the motor vehicle based on recognition in an image by the traffic monitoring device at least one of: a front side of the motor vehicle, or a rear side of the motor vehicle; and
a detecting arrangement to detect the wrong-way driving incident when the moving direction is against a direction of traffic of the unidirectional roadway.

19. The traffic monitoring device of claim 18 , wherein the traffic monitoring device is part of a toll system.
