PROBLEM TO BE SOLVED: To provide a work vehicle automatic traveling system which functions appropriately even when a plurality of work vehicles are put into a vast work area. SOLUTION: The work vehicle automatic traveling system has an area setting unit for setting a work area in an outer peripheral area SA and a work target area CA, and a large number of travel route elements constituting a travel route covering the work target area CA. And the route management unit that readablely manages the orbital route elements constituting the orbital route that orbits the outer region and the middle division region, and the work target area CA so that the work vehicle 1m and 1s can work on the next It is provided with a route element selection unit for selecting the next travel route element or the next circuit route element to be traveled. [Selection diagram] Fig. 25【課題】広大な作業地に複数台の作業車が投入される場合であっても、適切に機能する作業車自動走行システムを提供する。【解決手段】作業車自動走行システムは、作業地を、外周領域ＳＡと、作業対象領域ＣＡとに設定する領域設定部と、作業対象領域ＣＡを網羅する走行経路を構成する多数の走行経路要素と、外側領域及び中割り領域を周回する周回経路を構成する周回経路要素とを読み出し可能に管理する経路管理部と、作業対象領域ＣＡが作業車１ｍ、１ｓで作業走行されるように、次に走行すべき次走行経路要素または次周回経路要素を選択する経路要素選択部とを備えている。【選択図】図２５
