I am not aware of any academic research. Since the common excuse when there is collision is "I didn't see..." it stands to reason that a larger object will be easier to see. We appear larger to vehicles in front of us and behind us when we are side by side. It has been demonstrated that a group of cyclists is faster to pass when they are side by side as opposed to strung out.
