The committee recommends that the road weather research program routinely monitor research parallel to surface operations in aviation, rail, and transit to exploit applicable overlap. Many aspects of the proposed road weather research program could benefit research in aviation, rail, and other modes of transportation. Indeed, there are many synergies and efficiencies to be gained by coordinating research on meteorological phenomena that affect all modes and on the development of decision support resources. In particular the well-established aviation weather research programs offers many lessons learned that should be examined by the emerging road weather research program.
