Abstract
A paving machine including a frame, a hopper assembly, and a control unit is disclosed. The control unit may be configured to determine a location of the paving machine, determine a heading and a travel speed of the paving machine, and generate a non-circular geofence corresponding to the paving machine. The non-circular geofence may have an anchor point that is disposed at the location of the paving machine, and may be positioned and oriented based on the heading and the travel speed of the paving machine. The control unit may be configured to determine a location of a supply machine relative to the paving machine, and determine a state of the supply machine based on a comparison between the location of the supply machine and the non-circular geofence. The control unit may be configured to cause an action to be performed based on the state of the supply machine.
