@CjkOvPDwQW In short, it’s not correct, because the node is not associated to the way that is controlled. See “How to map on the wiki”: https://wiki.openstreetmap.org/wiki/Tag:highway=speed%20camera?uselang=en. The simple method is a node part of the way (to represent the existence of a control at that place). The more advanced is an isolated node (for the physical location of the camera) but make it part of a three-node relation to represent the direction of the control and link it to the way.
