A study was conducted of the heavy-duty (air, ship and rail) transportation system to determine where opportunities exist for R and D that could substantially reduce future energy requirements and fossil fuel dependence. The results of this assessment indicate that a substantial reduction can be made while still accommodating the demand and intermodal shifts which are projected. The pivotal issue will be the extent to which air cargo will displace the traditional and more energy conservative modes of shipment. From six major efforts selected, programs for a national initiative have been formulated which fall into three major categories: Improved efficiency through advanced vehicle and engine concepts; improved effectiveness by providing options in intermodal shifts that are more energy conservative with the introduction of new vehicle concepts; and fuel diversification which would decouple the heavy-duty system from petroleum dependence by introducing new vehicle and engine concepts. Characteristically these categories, on a technology basis, require vehicle and engine R and D since these are the areas of the transportation system for which new technology exerts greatest leverage.
