Road vehicles — Box task to measure cognitive and visual-manual workload

Scope

This document defines key terms and parameters applied in the analysis of cognitive and visual-manual workload induced by transport information and control systems (TICS). It provides guidelines and minimum requirements on equipment and procedures for analysing cognitive and visual-manual load including assessment of TICS to:
— plan evaluation trials;
— specify (and install) data capture equipment; and
— validate, analyse, interpret and report metrics indicating cognitive and visual-manual demand (standards of measurement).

The described parameters and definitions provide a common source of reference for cognitive and visual-manual workload induced by TICS. It is applicable to standardized trials in laboratory-based settings. The procedures described in this document can also apply to more general assessments of cognitive and visual-manual workload while driving. Data collected and analysed according to this document will allow comparisons to be performed across different TICS applications.
