Road alignment (circle, serpentine) (ensure that any curves are adequate to
support the design vehicles, recommend minimum of AASHTO WB-50 (WB-
15m));
Drop-in or retractable bollards (to cause serpentine traffic flow);
Gates or barriers that redirect traffic (may be moveable manually or
mechanically if not in use);
Speed humps or speed tables; and
Pavement texture.
Additional information on traffic calming can be found in Traffic Engineering and
Highway Safety Bulletin: Traffic Calming; Traffic Calming, State of the Practice; and at
6-2.1.2 Temporary Measures
Temporary barriers may be required by the installation's AT Plan for certain FPCONs.
These may include jersey barriers, water-filled plastic barriers, or similar obstructions to
reduce the number of lanes and reduce the speed of oncoming traffic. Incorporate
design details to support the installation of temporary barriers. This may include pre-
positioned sleeves or anchors to secure temporary bollards, etc. Any obstructions in
the roadway must be clearly marked and identified with Type III Barricade markings,
retroreflective red and retroreflective white stripings, in accordance with the MUTCD.
For additional guidance for temporary traffic control measures, refer to Traffic and
Safety Engineering for Better Entry Control Facilities.

Layout Guidelines for the Access Control Zone
Design the access control zone to manage authorized vehicles and personnel, to reject
unauthorized vehicles, and minimize the adverse impacts on traffic.
Base the layout of the access control zone on the following guidelines.
1. Provide infrastructure to support manual and automated identification and
inspection procedures for the inbound lanes. Configure the access control
zone to support tandem processing.
2. Where outbound lanes are designed to be reversible, security regulations
periodically require the inspection of exiting vehicles, or there is a potential for
automated monitoring of exiting vehicles as part of an automated access
control system infrastructure to support manual and automated identification
procedures should be provided.
3. The main identification area should be covered with an overhead canopy to
protect against inclement weather, facilitate identification and inspection
procedures, and provide a platform for lighting and CCTV. See paragraph 6-
9.5 for further canopy requirements.
4. As illustrated by the functional diagrams shown in Figures 3-1 through 3-3 there
may be the need for several rejection points from an ECF. Provide a minimum
