Patent ID: 8639435

Claim:
Method for conclusively capturing a violation of a permissible maximum speed on a section of a roadway having at least one traffic lane, wherein a vehicle is detected at a detection time and an image is recorded when the vehicle passes, respectively, an entry point and an exit point of a section of road, and the respective detection time is acquired, and the respective image recording is correlated, the vehicle registration plates of the passing vehicles are detected from the image recordings, and the image recordings of vehicles having the same vehicle registration plate are correlated with one another, an average speed of a vehicle is determined from the detection times for a same vehicle and knowledge of the length of the section of road according to the path-time law by calculating the quotient from the length of the section of road and the difference of the detection times, and the average speed is compared with a permissible maximum speed, wherein a high-resolution image recording of the driver of the vehicle is triggered with simultaneous flash illumination when the average speed exceeds the permissible maximum speed by a predetermined value, and the passenger space of the vehicle is illuminated in such a way that the driver can be identified in the image recording, and information needed for prosecuting the traffic violation such as the determined average speed, the permissible maximum speed, the vehicle registration plate recorded at the entry point and at the exit point, and place data and time data are superimposed in the image recording, characterized in that the two detection times are acquired, respectively, by two timer units which are independent from one another, and two differences are calculated, the greater of the two being used for determining the average speed.
