10. A gate crossing mechanism comprising:
a gate;
a motor operably coupled to the gate;
a controller including a battery and gate control circuitry configured to provide power to the motor, the controller being configured to control operation of the motor and receive gate control signals providing power;
a supercapacitor coupled to the battery, the supercapacitor being charged by the battery;
wherein the controller is configured to perform a method, the method comprising:
detecting a loss of power to the motor based on a loss of battery power and loss of the gate control signals; and
responsive to detecting the loss of the power, providing, by the supercapacitor, power to the motor to initiate the gate moving from an open position to a closed position; and
recharging the supercapacitor using the battery until the supercapacitor has a charge level at least equal to a high charge threshold, and
maintaining the charge level equal to the high charge threshold by providing a trickle charge from a voltage supply derived from the gate control signals.
