<P>PROBLEM TO BE SOLVED: To provide a conveyance truck system capable of improving conveyance efficiency by eliminating the need to make a conveyance truck stop when its destination is changed. <P>SOLUTION: When the destination of the conveyance truck 24 is changed from a point 20 to a point 18, the speed of the conveyance truck 24 is controlled to calculate a new travel route to the nearest branch point 10. The conveyance truck 24 cancels a straight travel at the branch point 10, a straight travel at a confluence point 14, and branching at a branch point 12 of blocking which becomes unnecessary, and requests again blocking for branching at the branch point 10 to travel according to the new route. <P>COPYRIGHT: (C)2007,JPO&INPIT |
