There are two distinct aspects of intermodal terminal inventory systems: terminal inventory control, which deals with the routine operation of locating equipment within the terminal, and automated equipment identification (AEI), which deals with the problem of encoding each trailer which enters a terminal and when it leaves. There are several types of AEI technologies in use: temporary bar codes (paper labels); optical character recognition; and radio frequency tags, temporarily or permanently affixed to the vehicle. The Association of American Railroads and the Massachusetts Institute of Technology conducted a survey of railroads to determine what the railroad requirements are for an AEI system. The survey found that few terminals have individually marked parking spaces and that virtually no terminals assign equipment to specific areas. Inventories are performed from 0 to 3 times per day, requiring 0.5 to 24 man-hours to perform. Included in this paper are responses to questions posed to the railroads about the severity of their problems in locating equipment in the terminals and their operations of AEI systems to expedite inventory control.
