Driver Workload Comparisons among Road Sections of Automated Highway Systems

The aim of this research was to compare driver's workload among AHS (Automated Highway Systems) road sections in a virtual AHS environment that is based on a real Korean expressway in order to predict and compare the workloads imposed by the change of driver-vehicle interface and vehicle control authority. Road sections included the ML (Manual Lane), TL1 (Transition Lane to enter the automated lane), AL (Automated Lane), TL2 (Transition Lane to enter the manual lane after the end of automated driving), and post-AHS manual lane.
