Controlled Access Zone/Entry Control and Vehicle Access

The objective of the access point is to prevent unauthorized access, while at the same time controlling the rate of entry for vehicles and pedestrians. An access point is a designated area for authorized building users: employees, visitors, and service providers. Access points along the defended perimeter:

1. Reject vehicles before final barrier

2. Inspection area blast effects:

  • Pressure
  • Fragments

3. Provide reaction time to activate barriers

It is advisable to design circulation to separate different types of traffic and provide separate routes for staff, for visitors, and for deliveries. With the separation of vehicle types, security can more easily address differing needs for screening, observation, and potential threat mitigation.
