Abstract: Automated gate entry/exit authorization systems and methods may comprise various sensor systems to detect a vehicle proximate a gate of a facility. Various detected data of the vehicle may be consolidated into a gate sensor event, and the gate sensor event may be compared with pre-registration information to determine whether the vehicle is scheduled to depart or arrive via the gate. If the gate sensor event corresponds with a scheduled appointment, further instructions may be provided to the vehicle related to the facility or yard, and the gate may be automatically opened to provide access. Alternatively, if the gate sensor event does not correspond with a scheduled appointment, further information or instructions, such as corrective or remedial actions, may be provided to the vehicle, and access via the gate may be automatically denied.
