Petroleum Liquids Pipelines Continue To Increase Transported Volumes

摘要

Data are in short ton-miles. A ton-mile is one ton of freight shipped one mile-a combined measure of both the weight shipped (short tons or 2,000-pound tons) and the distance (miles). Ton-miles in this report provide a common measure for considering the relative contribution and efficiency of the various modes of petroleum transportation. In addition, ton-miles can be useful in considering other variables such as safety and economic service.
