Boom Barrier

A "boom barrier" is a gate system that uses a long, horizontal arm that can be raised or lowered to control vehicle access, essentially acting as a barrier to block traffic when lowered and allowing passage when raised; it operates automatically using sensors and a motor, typically controlled by a security access system to regulate entry and exit at places like parking lots, toll booths, or residential complexes. 

Key points about boom barriers:

• Function:
  The primary function is to regulate traffic flow by allowing only authorized vehicles to pass through by raising the barrier arm when needed. 

• Mechanism:
  The barrier arm is attached to a motor which raises and lowers it, controlled by a control unit that receives signals from sensors like loop detectors or photocells. 

• Access control:
  Boom barriers can be integrated with various access control systems like RFID cards, license plate recognition, Fast tags or keypads to verify authorization before raising the barrier. 

• Safety features:
  Most boom barriers have safety features like obstacle detection sensors to prevent damage if a vehicle is too close when the barrier is lowering. 

Where are boom barriers used?

• Parking lots: To control entry and exit of vehicles in private or public parking areas 

• Toll booths: To collect tolls from vehicles on highways 

• Residential complexes: To restrict access to unauthorized vehicles in gated communities 

• Industrial sites: To manage vehicle traffic within industrial premises 

• Airport terminals: To regulate access to specific areas within an airport
