In choosing a transportation mode for a particular product, shippers consider as many as six criteria: speed, frequency, dependability, capability, availability and cost. Thus if a shipper seeks speed, air and truck are the prime contenders. If the goal is low cost, then water and pipeline are the prime contenders.
