But there are procedures and products to protect the airport perimeter, including barriers and bollards to protect from vehicle attacks as well as traffic controllers for vehicle access control. And there also are improvements in door access controls for airport and airline employees. The advances in these latter areas also impact security operations at corporate and commercial organizations.
For example, as part of a multi-million dollar enhancement at the Port Columbus International Airport in Ohio, Delta Scientific, Valencia, Calif., motorized traffic controllers are on the first two levels of the multi-level parking garage. These levels accommodate 1,200 rental vehicles, rental transaction counters and vehicle wash and fuel centers. The Delta MTC31 motorized traffic controller provides protection against unauthorized vehicle traffic into or out of protected areas. It incorporates what Delta calls Sabre Tooth Control Teeth that are rotated into position.
