In the months following the terrorist acts of Sept. 11, 2001, intense effort has been focused on understanding the state of security of travel on the nation's roadways, and on improving the existing level of security. These efforts have taken place within and across modes and between agencies that had not previously had reasons to work together. The activity has encompassed agencies at federal, state, and local levels, as well as the private sector, academia, and many associations supporting these participants. Progress has been significant but not particularly visible. This paper describes some of the effort, the findings, and the results. |
