NOTE: Michon (1985) defines operational driving functions as those delivered over a time constant of milliseconds and include tasks such as steering inputs to keep within a lane or braking to avoid an emerging hazard; tactical driving functions are those delivered over a time constant of seconds and include tasks such as lane choice, gap acceptance and overtaking. The DDT excludes strategic functions, which are those delivered over a longer time constant and include tasks such as trip scheduling and selection of destinations and waypoints.
