When used in a parking control application, a high
speed barrier gate is equipped with an automatic control logic and
vehicle loop detectors. A number of other features are also added
such as anti-tailgating, vehicle counting for monthly (contract)
parkers and transient (hourly) parkers, and electronic reversing
logic to cause the gate arm to reopen should it strike an object
during descent.
A variety of access controls for monthly parkers including card
readers, keypads, and radio controls can be used. These controls
can be used at the entrances and the exits or the exit could open
automatically.
