Privately Owned Vehicle (POV) Inspections
Commercial/Large Vehicle Inspections
When an installation has a limited number of access points, functional requirements
may be combined at the ECF. For example, an installation with only one ECF may
combine all of the above functions, or may use a centralized truck inspection facility that
is separate from the ECFs or the installation. A large installation may designate one
ECF for truck inspection and commercial vehicle access only. Not requiring support for
all functions at each ECF will reduce the infrastructure requirements. Additionally, when
designating the functions for all ECFs at an installation, give consideration to the
requirements to support oversized, atypical vehicles such as those frequently
encountered during construction operations or during mobilization of military vehicles
and equipment. These atypical vehicles should be supported by at least one limited use
or primary/secondary ECF, which may require modifications such as wider lanes,
limiting the use of channelization islands, or limiting potential obstructions.
When possible separate truck and passenger vehicle traffic. For traffic lanes that
require speed management to delay a high performance passenger vehicle, exclude
truck traffic from these lanes. The effectiveness of most speed management
techniques for passenger vehicles decreases when trucks must use the same lanes.
Also, search requirements differ significantly for trucks and passenger vehicles.
Consider separate search facilities for those types of traffic to avoid congestion and
improve efficiency of search guards during higher FPCON.
ECF FUNCTIONAL DIAGRAMS
The functional diagrams shown in Figures 3-1 through 3-3 illustrate general
relationships and desired adjacencies for different types of ECFs. These can be
modified based on installation or site-specific requirements for an ECF.
