Economic and Regulatory Aspects of Interlining

摘要

Interlining occurs when a shipment is handled by more than one carrier. The economic and regulatory reasons for motor carrier interlining are discussed and a taxonomy of interlining is developed. Interlining from necessity occurs when a carrier doesn't have sufficient operating authority to carry a shipment from origin to destination. It was found that convenience interlining has been accepted, if not endorsed, by the Interstate Commerce Commission. A potential danger of market division was recognized. Finally, the extent of interlining activity reported in the 1976 Continuing Traffic Study was displayed. The data show that interlining is a frequent occurrence, affecting many shippers. The incidence of interlining increases with the length of haul and with the remoteness of the points of origin and destination. Interlining frequency increases as shipment weight decreases. Shipments to or from small communities, those with fewer than 16,000 residents, are especially likely to be interlined.
