摘要： A display unit for a road machine includes a display and processing circuitry. The road machine includes a tractor, a hopper installed in front of the tractor to receive a paving material, a conveyor configured to feed the paving material in the hopper to the back side of the tractor, a screw configured to lay and spread the paving material fed by the conveyor behind the tractor, a screed configured to lay and level the paving material laid and spread by the screw behind the screw, and an information obtaining device configured to obtain information on road pavement. The processing circuitry of the display unit is configured to predict a future event based on the information on the road pavement obtained by the information obtaining device, and to display information on the event on a road map on the display.
