Claim 4:
5. A travel path generation system that generates a travel path for performing automatic travel in a field in which work is performed by different types of field work vehicles, the system comprising:
a work information storage management portion for storing and managing work information in a form in which the work information is linked with corresponding field information and corresponding work vehicle information, the work information being uploaded after being generated by a preceding field work vehicle previously performing work in the field, the preceding field work vehicle being in a form of a seeding machine or a rice transplanter as a seedling row forming machine for forming seedling rows;
a work information acquisition portion for acquiring, from the work information storage management portion, a seedling row formation map included in the work information regarding the preceding field work vehicle; and
a path calculation portion for calculating, based on the seedling row formation map, a subsequent field work vehicle travel path for a subsequent field work vehicle that is to perform automatic travel work hereafter in the field in which work has been performed by the preceding field work vehicle,
wherein the path calculation portion calculates the subsequent field work vehicle travel path with use of positions of the seedling rows and a direction in which the seedling rows extend, the positions and the direction being obtained based on the seedling row formation map, the subsequent field work vehicle travel path being calculated such that the subsequent field work vehicle travel path includes a first path and a second path, the first path extending in the direction in which the seedling rows extend, the second path extending in a direction crossing the direction in which the seedling rows extend, the first path being longer than the second path.
