A travel route generation apparatus includes: a work field data input unit that inputs work field data including external shape data of the work field； a travel route generation unit that generates the travel route corresponding to a designated travel route pattern designated by a user, based on the designated travel route pattern and the work field data； a touch panel 42 that receives handwriting input of a travel route image made by the user； and a travel route pattern determination module that detects a handwritten locus from the handwriting input and provides the travel route generation unit with a travel route pattern in correspondence with the detected handwritten locus from among a group of travel route patterns, as the designated travel route pattern.
