A platoon travel system that allows a plurality of moving objects to perform a platoon travel, the platoon travel system comprising: a plurality of moving objects each capable of performing a pivot turn; characterized in that each moving object having a control device configured to control the moving object, wherein the plurality of moving objects includes: a leading moving object configured to perform a manual travel or an autonomous travel, and moving objects (10B, 10C, 10D) other than the leading moving object configured to follow a moving object ahead of itself, and when stopping a platoon of the plurality of moving objects, each control device is configured to stop each of the moving objects in a state where each of the plurality of moving objects has a predetermined inter-moving-object distance from an adjacent moving object among the plurality of moving objects, the predetermined inter-moving-object distance being a distance allowing the moving object to perform a pivot turn of 180 degrees, wherein after stopping the platoon of the plurality of moving objects, each control device is configured to cause its moving object to perform the pivot turn, and after performing the pivot turn, each of the plurality of moving objects is configured to check existence of a front moving object, wherein a moving object that cannot check the existence of the front moving object among the plurality of moving objects (10A, 10B, 10C) is configured to recognize itself as a head of the platoon, and wherein the moving object that has recognized itself as the head of the platoon is configured to transmit a head declaration signal to the leading moving object. a plurality of moving objects each capable of performing a pivot turn; characterized in that each moving object having a control device configured to control the moving object, wherein the plurality of moving objects includes: a leading moving object configured to perform a manual travel or an autonomous travel, and moving objects (10B, 10C, 10D) other than the leading moving object configured to follow a moving object ahead of itself, and a leading moving object configured to perform a manual travel or an autonomous travel, and moving objects (10B, 10C, 10D) other than the leading moving object configured to follow a moving object ahead of itself, and when stopping a platoon of the plurality of moving objects, each control device is configured to stop each of the moving objects in a state where each of the plurality of moving objects has a predetermined inter-moving-object distance from an adjacent moving object among the plurality of moving objects, the predetermined inter-moving-object distance being a distance allowing the moving object to perform a pivot turn of 180 degrees, wherein after stopping the platoon of the plurality of moving objects, each control device is configured to cause its moving object to perform the pivot turn, and after performing the pivot turn, each of the plurality of moving objects is configured to check existence of a front moving object, wherein a moving object that cannot check the existence of the front moving object among the plurality of moving objects (10A, 10B, 10C) is configured to recognize itself as a head of the platoon, and wherein the moving object that has recognized itself as the head of the platoon is configured to transmit a head declaration signal to the leading moving object.
