Review of Related Literature Ports of entry (airports, seaports) and border crossings are vulnerable points in the transportation network where heightened security is essential. This has led the Transportation Security Administration (TTS) to inspect all cargo traveling on passenger planes and use a risk-based screening process for inspecting commodities moving on air cargo carriers. Similar considerations are in effect at U. S. Seaports, where more than nine million marine containers arrive each year (CARS, 2005).

Here, he Bureau of Customs and Border Protection analyzes cargo and utilizes other information to target specific shipments for closer inspection. However, tests of the screening system have demonstrated that existing devices have been unable to consistently detect containers carrying dangerous goods (Volvo, 2008; Cochran, 2008), suggesting that an even tighter screen protocol is required. While the need to impose strict security measures at points of entry Is not disputed, these practices can have a detrimental effect on freight mobility.
