transmit a message from the transport vehicle to the construction machine when the transport vehicle approaches the construction machine; and responsive to the message, to transmit from the construction machine to a reception and display device arranged at or in the transport vehicle one or more of: first data comprising the image data; second data determined from the image data; and third data comprising one or more detected operating parameters of the milling machine, data determined or derived from the one or more detected operating parameters of the milling machine, and/or data relating to milling material loaded onto the transport vehicle. ### Claim 2 (depends on 1) The computer system of claim 1, wherein the transmissions from either one of the construction machine or the transport vehicle are further stored in either or both of the respective storage devices residing on the construction machine and/or the transport vehicle. ### Claim 3 (depends on 1) The computer system of claim 1, further configured to detect and transmit a message to the construction machine comprising a mass of the milling material loaded onto the transport vehicle. ### Claim 4 (depends on 1) The computer system of claim 1, wherein the data relating to milling material loaded onto the transport vehicle comprises one or more material properties of milling material loaded onto the transport vehicle and/or a location from which the milling material was milled. ### Claim 5 (depends on 4) The computer system of claim 4, wherein the data relating to milling material loaded onto the transport vehicle comprises material properties of the milling material at corresponding locations, or at one or more different layers for each corresponding location. ### Claim 6 (depends on 1) The computer system of claim 1, wherein the one or more operating parameters comprise one or more of: a milling depth; a milling volume removed; an advance speed; a milling drum speed of revolution; a relation between advance speed and milling drum speed of revolution; a milling drum used; a torque/output emitted by a drive engine of the milling machine; and/or an amount of water fed during a milling process to cool milling tools of the milling drum. ### Claim 7 (depends on 6) The computer system of claim 6, wherein the third data comprises physical properties of the milling material determined from a relation between an advance rate of the milling machine and a milling drum speed of revolution. ### Claim 8 (depends on 6) The computer system of claim 6, wherein the third data comprises which layer of a ground pavement has been milled, wherein the layer of the ground pavement which has been milled is determined from a detected milling depth at a respective location of the ground pavement. ### Claim 9 (depends on 1) The computer system of claim 1, wherein: the second data determined from the image data comprises one or more of: a filling level in the loading space;
