I have Saturn road network (Not geographically aligned) which I have to aligned as per actual ITN road network from OS into separate layer named output_line. What is the best way to snap Saturn link over ITN links with attribute(A_Bnode ~ 24111_25111). Please note that most of times Saturn link are bi-directional overlapped on top each other e.g 24111_25111 and 25111_24111. It take lots of manual work to copying pasting merging road segments then attributing it to 24111_25111 and again copy this whole link and flipping the direction with attribute 25111_24111.
