Abstract: A driving support system includes a device control unit that outputs operation control signals to a travel operation device causing a traveling vehicle body to travel and a work operation device causing a ground work apparatus to operate. A recorder records control data in execution processing order as a work/travel sequence. A reproducer reads out the control data recorded by the recorder and transmits the control data to the device control unit. A screen processor converts the control data for each execution processing unit to an icon and displays in a display a work/travel sequence screen displaying the icon in the execution processing order. The system manages a plurality of the work/travel sequences on the same work/travel sequence screen.
