The tragic events of September 11, 2001, raised America's awareness of global terrorism and, as a function of how the attacks were carried out, placed special attention on transportation and aviation security in particular. In the weeks and months that followed, efforts to increase homeland security were widespread. In almost every case, however, very little attention was paid to ground transportation issues. The purpose of this research was to characterize the task of protecting ground transportation systems, especially urban mass transit services but also intercity highways and railroads, and identify the factors that affected how those facilities were being secured in the wake of September 11th. |
