An automated forwarder traveling continuously on the same track produces more noticeable road surface deformations than a manually operated forwarder. Continuous travel with reduced road surface deformation can be possible by specifying the characteristics of manual travel. Additionally, automated travel can reduce labor and other costs. Therefore, we conduct continuous travel tests with the automated and manual forwarders and specify the road deformations and characteristics after each test. The results demonstrate that turning causes more soil to fill than sink for both types of travel. Additionally, the soil filled up in the curved section is particularly noticeable in automated travel. The operators in the manual forwarder do not follow the same track. Generally, the tracks departed from the previous ones by more than 0.2 m on either side. This type of travel seems to have a leveling effect on the deformed road surface; thus, it can be used for automated travel. The road for automated travel must be at least 0.2 m wide on each side in addition to the width needed for road safety. However, creating wide roads in certain locations, such as steep slopes, is challenging. Alternatively, using forwarders with small widths instead of constructing wider roads leads to lower total productivity.
