Summary
This study investigated whether extended travel under automated control in an Automated Highway System affects subsequent manual driving performance. Using the Iowa Driving Simulator, 48 drivers (half aged 25-34, half aged 65+) participated in a generic AHS configuration where the left lane was reserved for automated traffic. Drivers in the experimental group traveled under automated control for at least 35 minutes at speeds exceeding the limit and with short intra-string gaps, while a control group drove manually throughout. Performance metrics including lane keeping, speed control, following distance, and gap acceptance were compared before and after the automated period. The results indicated that extended automated travel did not adversely affect lane keeping or speed control, though minimum following distances and rejected gap sizes may have decreased. Drivers also expressed a preference for larger gaps than those experienced and preferred simultaneous transfer of steering and speed control.
Key finding
Extended travel under automated control did not have an adverse effect on lane keeping and speed control, but may have led to decreased minimum following distances and smaller rejected gap sizes during subsequent manual driving.
