An autonomous travel vehicle (100) includes a platform portion (1), a traveling unit (2), a storage unit (73), a arrival position prediction unit (7531), a corrected speed calculation unit (7533), and a reproduction travel command calculation unit (7535). The traveling unit (2) controls the platform portion (1) to travel in accordance with a travel control command. The storage unit (73) stores travel route data (500), which stores subgoal points, arrival times, and traveling speeds in association with each other. In the reproduction travel mode, the arrival position prediction unit (7531) predicts a predicted arrival position (P_(O)). In the reproduction travel mode, the corrected speed calculation unit (7533) calculates a corrected traveling speed based on a predicted traveling distance (L_(e)) and a required traveling distance (L_(r)). The reproduction travel command calculation unit (7535) calculates a reproduction travel control command based on the corrected traveling speed, as the travel control command.
