A system and method are provided for evenly distributing the loading of material in a loading container of a transport vehicle (e.g., articulated dump truck) by a work machine (e.g., excavator). At least one sensor mounted on the work machine generates data corresponding to at least a portion of the loading container. The captured data is processed to determine a current profile of material loaded in the loading container, wherein output signals are generated corresponding to a difference between the current profile and a predetermined target profile for the material loaded in the loading container. In certain embodiments, the output signals are used to assist an operator of the work machine with manual loading via an onboard display unit and superposed images associated with the current and/or target profiles. In other embodiments, the output signals automatically control at least part of the loading process.

A system and method are provided for flow synchronization between various transport vehicles (e.g. dump trucks) and a work machine (e.g. excavator) in a material loading cycle. The work machine and each transport vehicle are configured to communicate with each other via a machine-to-machine communications network. A controller determines initiation of a loading cycle associated with the work machine and a first transport vehicle, and detects certain parameters corresponding to a duration of the loading cycle (e.g. weight of payload, volume of truck bin, historical cycle data).
