1. A conveyance system that receives a signal including order information received from at least one terminal and stores the order information in a storage device, the conveyance system configured to set a travel route for an automated guided vehicle (AGV) so as to move the AGV to a destination position to carry at least one item, included in the order information, from a first position to the destination position, the conveyance system comprising:
at least one controller configured to:
receive, from a server, a movement request to move the AGV
set a section travel route to form a part of the travel route from a current position of the AGV to the destination position based on the received movement request such that the section travel route of the AGV does not overlap another section travel route set for another AGV,
determine a length of the section travel route based on information on a portion within a determined length set in advance from a start position of the section travel route, and
transmit an operation signal to the AGV and the other AGV, wherein the section travel route includes a first section travel route and a second section travel route, the at least one controller is further configured to repeatedly execute setting the second section travel route with an end position of the first section travel route as a start position of the second section travel route while the AGV is traveling on the first section travel route, and
the length of the section travel route is determined based on one or more of:
(i) whether or not a position of a specific intersection with a high possibility of a collision of a plurality of AGVs, including the AGV and the other AGV, among a plurality of intersections where a plurality of aisles intersect each other, exists within the determined length from the start position of the section travel route,
(ii) whether or not a low-speed travel aisle, on which the AGV travels at a low speed, exists within the determined length from the start position of the section travel route
(iii) whether or not the portion within the determined length from the start position of the section travel route is included in a low-speed travel area in which the AGV travels at a low speed,
(iv) whether or not a right/left turn point exists within the determined length from the start position of the section travel route,
(v) or whether or not the portion within the determined length from the start position of the section travel route is included in a high-density area with a probability of occurrence of the collision of the plurality of AGVs being higher than a threshold value.

19. A conveying method in which one or more processors receive a signal including order information received from at least one terminal and store the order information in a storage device, the one or more processors configured to set a travel route for an automated guided vehicle (AGV) so as to move the AGV to a destination position to carry at least one item, included in the order information, from a first position to the destination position, the conveying method comprising:
receiving, from a server, a movement request to move the AGV;
based on the movement request, setting a section travel route to form a part of the travel route from a current position of the AGV to the destination position such that the section travel route of the AGV does not overlap another section travel route set for another AGV,
wherein the section travel route includes a first section travel route and a second section travel route;
determining a length of the section travel route based on information on a portion within a determined length set in advance from a start position of the section travel route;
repeatedly executing processings of setting the second section travel route with an end position of the first section travel route as a start position of the second section travel route while the AGV is traveling on the first section travel route and
transmitting an operation signal to the AGV and the other AGV,
wherein the length of the section travel route is determined based on one or more of:
(i) whether or not a position of a specific intersection with a high possibility of a collision of a plurality of the AGVs, including the AGV and the other AGV, among a plurality of intersections where a plurality of aisles intersect each other, exists within the determined length from the start position of the section travel route,
(ii) whether or not a low-speed travel aisle, on which the AGV travels at a low speed, exists within the determined length from the start position of the section travel route,
(iii) whether or not the portion within the determined length from the start position of the section travel route is included in a low-speed travel area in which the AGV travels at a low speed,
(iv) whether or not a right/left turn point exists within the determined length from the start position of the section travel route, or
(v) whether or not the portion within the determined length from the start position of the section travel route is included in a high-density area with a probability of occurrence of the collision of the plurality of AGVs being higher than a threshold value.
