6 DESIGN GUIDELINES
6-1
INTRODUCTION
The following design considerations are provided for ECFs controlling DOD Personnel
Only (Authorized Vehicles), DOD Personnel / Visitors, and Commercial / Large Vehicles
with a separate centralized inspection facility. For a Large Vehicle Inspection Facility
follow the additional guidelines in Chapter 7 which reflect the unique requirements of
supporting inspection functions for these types of vehicles.

GENERAL LAYOUT REQUIREMENTS
This section reviews the general layout requirements and design guidelines for the
various zones of an entry control facility. Further details concerning specific elements
are provided in later sections.
Many of these design guidelines are illustrated in Figures 6-1 through 6-4. Figure 6-1
illustrates an ECF with manual identification and inspection procedures. Figure 6-2
illustrates the same ECF operating using an automated access control system. Figures
6-3 and 6-4 illustrate alternative layouts of the access control zone using pull-off
inspection areas in lieu of a separate inspection lane.

Layout Guidelines for the Approach Zone
Design the approach to the installation to accommodate peak traffic demand without
impeding traffic flow in the surrounding road network. Additional traffic considerations
are discussed in later sections. See Traffic and Safety Engineering for Better Entry
Control Facilities for design guidance concerning traffic demand and lane capacity.
Base the layout of the approach zone on the following guidelines:
1. Maximize the length of the approach zone, to provide optimal stacking distance
for the traffic queue.
2. Reversible lanes can increase throughput and flexibility where space is
unavailable for additional lanes.
3. Sort traffic by vehicle type. For example - use the farthest right lane for truck
traffic. Rejection of these vehicles requires additional space for their larger
turning radii.
4. Separating vehicles with varying inspection requirements can also increase
throughput. For example - authorized personnel could use a separate lane with
automated equipment.
6-2.1.1 Traffic Calming
Traffic calming, or speed management, can be utilized for inbound lanes to control
vehicle speed and slow incoming vehicles before they reach the gate so that SF
personnel have adequate time to respond to unauthorized activities. This includes
provisions for restricting traffic flow approaching the access control zone (ID check
area) during increased FPCONs. Appropriate traffic calming measures include:
