Status of Cost, Rate, and Time-of-Transit Models for Network Links

摘要

The dollar- and time-cost properties of characteristics of rail and highway shipments on links are investigated. The basic assumption is that shippers will alter their choice of mode or route as changes occur in the perceived characteristics or properties of these routes. It is posited that their choice is based on three properties and characteristics: the cost (price) of the shipment; the time of transit; and the variability of delivery. Calculations were made for all direct costs; this includes the cost of the transport units but not the cost of the terminals. For the railways, this is the so-called over-the-rail costs. For the trucks, this is the cost that an owner-operator would face in owning and operating his own equipment. (ERA citation 05:007313)
