Around the World Trade Center site, a primary security concern is to screen against terrorists who would try to use a truck or car bomb.
Eyewitness News has learned, one possible security measure suggests a program to register trucks and car services that use the site on a daily basis. Others would have to be individually screened.
According to police documents looking into security around the site, appearing in a published report, preliminary discussion suggests a number of security checkpoints, guard stations, and barriers limiting travel through the site.
However, police officials stress this would have no impact on pedestrians and tourists. They would be allowed to freely move throughout the site.
On a larger scale, at four tunnels and three bridges,in an attempt to track and prevent a potential threat, the NYPD is hoping to scan the license plates of all vehicles entering Manhattan.
Also they would check for radiation, which is currently done at various radom sites.
