In this analysis of the competitive performance of railroad and highway operations based on market share data and cost information, total freight-haul tonnages as well as those for specific commodities are investigated to ascertain modal share in relation to both length of haul and shipment size. Trade-off factors are discussed, individual commodities are analyzed, and correlation analysis is used to compare the market penetration of the various freight transport modes in respect to individual commodities. The implications of the fuel situation are discussed. The study shows fairly good correlation between the modal share (tonnage) of the freight transport market and the independent variables of distance of haul and size of shipment, especially when total freight tonnage is used rather than individual commodities. Tonnage for various distances of shipment correlates better with a logarithmic curve than with an exponential or linear curve, while the exponential curve is better. Railroad's maximum penetration of the market is significantly higher when shipment size is used as an independent variable. The correlations for individual commodities in general agree with the analysis for total traffic, although significant variables were noted for individual commodities. The fuel situation it appears, will increase trucking costs and possibly decrease motor carrier service advantage relative to railroad operations.
