4.4.4 Traffic Control Devices
As a minimum "rumble strips" shall be utilized at the entrance to the entry control facility to
alert oncoming vehicles and prior to the active barriers in the outbound lanes to alert exiting
vehicles. The use of speed bumps, humps, etc. with a height greater than 0.5" above the
pavement surface is prohibited. Guardrails will be used to transition from shoulder to passive
vehicle barriers. Where active vehicle barriers or traffic arms are utilized, provide red and
white reflectorized arms or surfaces. As discussed in Section 3.4.2, at a minimum, all active
vehicle barriers will have warning signals placed prior to all active vehicle barriers in each
direction. The warning signals will have red and yellow lights; with the yellow light having the
ability to flash. When the active vehicle barrier is in the closed position (stopping vehicle
flow), a red stoplight should be used. At other times a yellow flashing light should be used
(1).
4.5 Pedestrian Considerations
Many entry control points handle vehicular and pedestrian traffic. Many installations may
have a significant pedestrian volume. Where pedestrian access control is required, insure
proper sidewalk and safety provisions to direct pedestrian traffic to the access control zone
and separate it from vehicular traffic. Pedestrian access should be designed to ensure
security personnel can maintain visual contact with the pedestrians as they approach the ECF.
Sidewalks shall be planned to integrate into the existing site layout and accommodate new
facilities. Breaks should be provided in the passive barriers to allow pedestrians access to the
entry control facility. Any break in the passive barrier shall not exceed 1 meter (3 ft.) in
width.
Provide sidewalks with a minimum width of 1.2 meters (4 ft.). Crosswalks shall be 1.8 meters
(6 ft.) in width. The ECF shall also incorporate turnstiles or similar devices that can be
automated to facilitate authorized access control. Ensure turnstiles incorporate access control
systems or are capable of being upgraded in the future. Other considerations in the selection
of turnstiles or similar access control devices include the control of potential tailgating and the
likelihood that personnel will have equipment or luggage, which may require additional space
in the turnstile.
4.6 Electrical Power Requirements
Electrical design shall consider current power demands as well as the power requirements for
future traffic control devices, identification equipment, and other devices associated with
potential automation of the entry control facility.
OPNAV 5530.14C specifies emergency power for protective lighting provided for restricted
areas. TM5-811-1 specifies an alternate electrical power requirement for security lighting.
Similarly, each ECF shall have provisions of an alternate electrical power source. In the event
of a loss of the primary electrical source, a reliable alternate power source is necessary to
ensure continuous operation of the ECF. A standby generator will be used as the alternate
electrical power source. Either automatic or manual starting of the generator and load
transfer will be provided depending on the permissible electric power outage duration (5). In
some cases, installations may specify the use of portable generators in addition to stationary
auxiliary electric power sources. Provision of portable units is not the designer's responsibility,
beyond providing a connection point when directed.
