Professor Abouchar examines the freight schedules introduced on the brazilian railways in 1968. He concludes that they will be more inflationary than the old rates, leading to still larger deficits and to increasing demand in directions that will be harmful to national efficiency.
The approach utilises a simultaneous equations system to derive a discrete/continuous choice model for the choices of mode and shipment size in the intercity freight market. The method is applied to the demand for intercity freight transport using data from the US Census of transportation.
Distribution has largely passed from control by the supplier to control by the retailer, and from own-account to contract operation. Improvements in the road network should make journey times more predictable. The “business potential” gained from the road improvements is often much larger than the time saved.
