PROBLEM TO BE SOLVED: To prevent, when generating work routes for one work vehicle and an other work vehicle, collision from occurring as the one work vehicle gyrates at an end of a farm field and proceeds in a direction opposite to the other work vehicle.SOLUTION: A plurality of work paths are arranged in parallel and adjacent to each other along which an autonomously traveling work vehicle 1 traveling ahead and a traveling work vehicle 100 traveling behind the autonomously traveling work vehicle 1 perform work, and a work route is set to which is added a work path number that is contiguous to each work path, with the order of work by the autonomously traveling work vehicle 1 assigned to the work path number, and the order of work by the traveling work vehicle 100 assigned to the work path number. When a difference between the work path number assigned to a prescribed work order of the autonomously traveling work vehicle 1 and the work path number assigned to an immediately preceding work order to a prescribed work order of the traveling work vehicle 100 is 1, the control unit 130 can execute a prescribed notification before a work route Ra is created by a work route generation unit.SELECTED DRAWING: Figure 6【課題】一方の作業車両と他方の作業車両の作業経路を生成するときに、一方の作業車両が圃場端で旋回して、他方の作業車両と反対方向に進行するときに、衝突が発生しないようにする。【解決手段】先に走行する自律走行作業車両１と、該自律走行作業車両１よりも遅れて走行する走行作業車両１００とにより作業される複数の作業路が平行に隣接して配されるとともに、各作業路に連続した作業路番号が付されて作業経路が設定され、前記自律走行作業車両１による作業の順番を前記作業路番号に割り付け、前記走行作業車両１００による作業の順番を前記作業路番号に割り付け、制御部１３０は自律走行作業車両１の所定の作業順に割り付けられた作業路番号から、走行作業車両１００の前記所定の作業順の一つ前の作業順に割り付けられた作業路番号の差が１となる場合、前記作業経路生成部により作業経路Ｒａが作成される前に、所定の報知を実行可能である。【選択図】図６
