Abstract
The invention is a system and method for managing a resource having multiple entry points. Each mobile machine includes a queue manager for generating a queue position request upon approach to the resource. A resource manager establishes queues, one for each entry point to the resource, to control access to the resource. Upon receiving a queue position request from an approaching mobile machine, the resource manager determines which queue to place the mobile machine, and then generates a queue position and sends a queue position signal to the approaching mobile machine.
