  • Patent number: 10845208
    Abstract: Systems and methods for estimating a dump location of material dumped by a transport vehicle are disclosed. A system may receive information that identifies a location of a paving machine, and may receive multiple data points associated with the transport vehicle. Each data point may indicate a respective location of the transport vehicle and a corresponding time at which the transport vehicle was at the respective location. The system may identify a subset of the multiple data points that indicate respective locations of the transport vehicle within a threshold proximity of the location of the paving machine. The system may estimate the dump location of the material dumped by the transport vehicle based on at least one of a set of locations indicated by the subset of data points or a set of times indicated by the subset of data points, and may output information that identifies the dump location.
