1. A sensor device that is configured to detect road users on a part of a traffic route, comprising:
- a transmitting and/or receiving device for transmitting and/or receiving a transmission beam; and
at least one determination device for determining an actual position and/or an actual orientation in which the sensor device is disposed,an electrical controller configured to compare the actual position and/or the actual orientation of the sensor with a target position and/or target orientation of the sensor to provide data for changing the actual position and/or actual orientation of the sensor to correspond with a target position and/or target orientation of the sensor; and
an electronic data memory which stores information about different sub regions of at least part of the traffic route or expected trajectories of which at least some road users travel along,wherein the sensor device is positioned in a target position above or next to the traffic route,wherein the electrical controller is configuredto determine an actual trajectory from data representing a plurality of road users detected at different points in time,to compare said actual trajectory with the expected trajectories or with the information about different sub regions of the at least part of the traffic route, andto determine a deviation of the actual elevation angle from the target elevation angle and/or a deviation of the actual azimuth angle from the target azimuth angle from a result of said comparison, andwherein the target orientation compared by the electrical controller comprises a target elevation angle and a target azimuth angle and wherein the at least one determination device is configured to determine an actual elevation angle and/or an actual azimuth angle and/or an actual tilt angle.

12. A road-monitoring sensor device that is configured to detect errors and deviations in its own position and/or orientation reducing detection of road users on a part of a traffic route, comprising:
- a transmitting and/or receiving device for transmitting and/or receiving a transmission beam; and
at least one determination device for determining an actual position and/or an actual orientation in which the sensor device is disposed, an electrical controller configured to compare the actual position and/or the actual orientation of the sensor with a target position and/or target orientation of the sensor to provide data for changing the actual position and/or actual orientation of the sensor to correspond with a target position and/or target orientation of the sensor; and
an electronic data memory which stores information about different sub regions of at least part of the traffic route or expected trajectories of which at least some road users travel along, wherein the sensor device is positioned in a target position above or next to the traffic route, wherein the electrical controller is configured to determine an actual trajectory from data representing plurality of road users detected at different points in time, to compare said actual trajectory with the expected trajectories or with the information about different sub regions of the at least part of the traffic route, and to determine a deviation of the actual elevation angle from the target elevation angle and/or a deviation of the actual azimuth angle from the target azimuth angle from a result of the comparison, deviation being treated as an error reducing a detection region, and to provide for correction of the error, wherein the target orientation compared by the electrical controller comprises a target elevation angle and a target azimuth angle and wherein the at least one determination device is configured to determine an actual elevation angle and/or an actual azimuth angle and/or an actual tilt angle. - View Dependent Claims (13, 14)
