I would use an area on area overlayer to separate the overlap, then dissolve the overlapping segment back into one of the roads. You will probably need some logic to ensure you dissolve back to the correct road segment.

I tried that way and the result became like this. Is there a way to fill that gap? Could you share the parameters of the transformers used?image
