for accommodating traffic calming techniques, such as temporary barricades
to reduce high‐speed threats. Due to the inadequate capacity for vehicle
queuing at Seymour Johnson’s main gate, vehicle stacking occurs out on to
South Berkley Blvd. and into the intersection with East Elm Street.
Berkley Blvd. is classified as a major arterial road within the City of Goldsboro
with a Level of Service (LOS) rating of E and specific corridors having an LOS
rating of F. According to the City’s 2040 Transportation Plan, a LOS of E
correlates to a roadway that is near capacity, and a LOS of F indicates that a
roadway is operating above capacity or failing. The Plan defines volume to
capacity (V / C) ratio according to the following measurements:
Approaching Capacity (V/C = 0.8 to 1.0): A roadway with a V / C less
than 0.8 typically operates with efficiency. As the V / C nears 1.0, the
roadway becomes more congested. Roadways near capacity may
operate effectively during non‐peak hours, and become congested
during morning and evening peak commuting times.
At and Over Capacity (V / C = >1.0): Roadways operating at or over
capacity experience congestion during peak and non‐peak hours, with
stop‐and‐go gridlock during peak travel times. Changes in capacity due
to roadway incidents greatly impact the flow of traffic on corridors
operating within this V / C range, and would be assigned an LOS rating
of F.
This level E rating indicates that Berkley Blvd is at least two classifications
below Goldsboro’s goal for maintaining a level of C or better for all roadways.
Isolated portions of Berkley Blvd which have been identified as having an LOS
of F include the corridor where South Berkley Blvd intersects with East Elm
Street at the entrance to Seymour Johnson’s main gate.
Queuing and stacking on public roadways can have an impact on more than
the LOS; it can lead to a potential increase in traffic accidents. Between 2007
and 2011, crash statistics from the North Carolina Department of
Transportation (NCDOT) show that the roadway along South Berkley Blvd.,
Page 5.20‐2
from the Base to US 70 includes several intersections which are noted for
high frequency crashes. The High Frequency Crash Location Map includes
the top 30 percent of intersections with 11 or more reported crashes, which
are mapped and categorized by frequency for crashes. During this time
frame, there were five intersections identified within approximately
4,000 feet of the entrance to the main gate that were associated with high
frequency crashes. Three of the intersections had the third highest ranking
of 30 – 39 crashes and two had the fifth highest ranking of 10 – 19 crashes.
Although the NCDOT Crash Report for 2014 does not provide the number of
accidents related to speed, numbers for the state indicate that speed was a
factor in nearly 35 percent of all crashes. Accidents caused by encountering
unexpected non‐moving vehicles on the roadway could be attributed to
various factors, and can be further exacerbated by heavy congestion.
Traveling at speeds that do not allow for quick and decisive maneuvers when
stopped vehicles are encountered on the roadway is one of the risks
associated with queuing vehicles on the roadway.

Facilities / Access Control Points UFC 4-022-01
The United Facilities Criteria: Security Engineering: Entry Control Facilities /
Access Control Points provides design and construction standards for entry
control / access control points that assist in providing security and
anti‐terrorism design elements needed for protecting military installations.
The standard provides the design standards for an entry control facility which
allow for persons and vehicles entering and leaving the installation to do so
safely, ensuring the protection of security personnel, pedestrians and other
vehicles. The standard is also meant to ensure a design that maximizes traffic
flow, while minimizing the impacts on safety, security, and public highway
use.
