Abstract: Systems and methods that allow use of simple priority VCUs (those that can only request an increased priority) to operate in a manner that simulates much more sophisticated schedule-adherence or ETA-type traffic control systems without the need to upgrade vehicle hardware. Instead, tracking of the vehicle, whether provided by other systems or by the VCU operating in conjunction with certain prepared points or zones is used to determine if the VCU equipped vehicle is ahead or behind schedule and operation of the VCU itself is altered to modify the expected arrival time of the vehicle.
