So that an obstacle region is set and a route is not generated in the periphery where an obstacle is positioned, and to have the route set in a work region avoid the obstacle region so as to be able to work efficiently: a control unit (30) of an autonomous traveling work vehicle (1), which is a route generating device that can generate a route for which autonomous traveling and work are possible within a field H; or a control unit (130) of a remote operating device (112), that is capable of communicating with said control unit (30), is able to set: a first region in which a work route Ra is generated for performing work in the field H; a second region set in the periphery of the first region, for which the work route Ra is not generated, but a travel route Rb for traveling can be generated; a third region within the field H for which travel is prohibited; and a fourth region set in the periphery of the third region, for which the work route Ra is not generated, but the travel route Rb for traveling can be generated.
