The document outlines the design and functionality of car park barriers used for traffic management in busy areas, detailing their automation and use of technology such as RFID for vehicle identification. It describes various types of barriers and their operation, including ticket generation and space availability monitoring. Key components include sensors, microcontrollers, and motorized mechanisms that permit automated entry and exit for vehicles.

2. • Car park barriers are the most common
method of managing traffic flow and parking
in busy or sensitive areas.
• Various boom barriers are primarily designed
to control traffic flow.
• Application ranges from private to
commercial including public car parks.

4. • Automatic detection of vehicle entering the car park.
• Automatic generation of ticket and lifting up of
entrance barrier & then lowering the barrier.
• For frequent users or staff, prepaid cards or tickets
have been provided and card reader machines are
placed at the entry point.
• Automated identification of ticket and lifting up of exit
barrier.
• Computerized computation of No. of vehicles in the car
park station and provides information about status of
car park station by showing ‘no space/available space’.

5. • Sensor (Ultrasonic transmitter & ultrasonic
detector)
• Microcontroller or Programmable logic
controller (PLC)
• Vehicle counter
• Barrier arms with motorized connection.
• Automated pay and ticket generation machine
• Central operation unit

6. • When a current flows through the solenoid of
valve, the piston in a cylinder moves upwards and
causes the barrier to rotate about its pivot and
raise to let a car through.
• When the current flow is stopped, the return
spring of the valve results in the valve position
changing back to its original position.
• When the current flows through another valve,
the pressure is applied to lower the barrier.
• Limit switches are used to identify whether
barrier is down or up.

7. • It is an automatic identification system.
• It consists of a RFID tags or transponders and a RFID
reader.
• The data or information about the vehicle is stored in a
RFID tag or transponder.
• The RFID tag can be affix or interpolated to a product
or vehicle for detection and tracking using radio waves.
• During the operation, these data has been retrieved by
the RFID reader.
• There are many different types of RFID systems in the
market. These are categorized on the basis of their
frequency ranges.

8. • A RFID system encompasses:
– An antenna or coil,
– a transceiver (with decoder) and
– a transponder (RFID tag) electronically
programmed with unique information.

11. • Barrier arm gates
• Cantilever gates
• Bi-folding gates
• Slide gates
• Vertical lift gates
• Swing gates
