Abstract: A method for detecting a traffic junction. The method includes: receiving position data describing a respective position history of motor vehicles traveling on roads which include the traffic junction and traveling through said traffic junction; ascertaining a respective curvature progression of the position histories; ascertaining a respective derivative, in particular a numerical derivative, of the curvature progressions to obtain a respective change in the curvature progressions over the respective position history; detecting the traffic junction based on the respective ascertained derivatives of the curvature progressions. A device, a computer program, and a machine-readable storage medium are also described.
