Impacts of Different Driving Automation Levels on Highway Geometric Design from the Perspective of Trucks

Figure 1

Schematic view of the driver’s tasks in L0∼L5 and measurements of the driver state. Note that (1) nondriving tasks (task 6) do not include those (turning a radio, scanning road signs, answering the phone, etc.) that only require short periods of eyes-off-road time and can be performed simultaneously with driving tasks; (2) strategic tasks (i.e., navigation), such as trip scheduling and route following, were not listed because the difference among automation levels does not include strategic aspects of driving.
