[Problem] To provide effective assistance when a transportation machine is relatively positioned so as to be in a position and direction optimal for loading work by a loading machine. [Solution] To advance a dump truck (2) quickly and smoothly to a position where a target loading work will be performed relative to an excavating machine (1), the dump truck (2) is placed in a loading target position relative to the excavating machine (1), a geographical position is detected from GPS satellites (30) by a GPS receiver (32) of the dump truck (2), the position and direction of the geographical position is transmitted to the excavating machine (1) as a target position image (P1), the target position image (P1) and an approach route (R) leading to the position are displayed on a display (36) of the dump truck (2) when the dump truck (2) thereafter approaches the position, and the dump truck (2) is driven so that a current position image (P2) advances along the approach route (R) to the target position image (P1), whereby the dump truck (2) is placed in the loading target position that has been set.
