Standardized names and definitions for driving performance measures

Historically, driving performance measures have been undefined or vaguely defined, and if defined, inconsistently used. Consequently, driving studies are difficult to compare and challenging to replicate, undermining the professional credibility of researchers and the field of automotive human factors.;This study developed names and definitions for 12 common lateral and longitudinal driving performance measures relating to: driving within and between lanes (lane departure, lane change, lateral lane position); steering wheel reversal; headway and gap (distance gap, time gap, distance headway, time headway); pedals (accelerator release time, accelerator to brake transition time, brake reaction time); and time to collision).;Human factors and lexicographical criteria were developed for defining driving performance operational definitions. Based on the criteria and literature, standard measure names and definitions were developed. It is intended that human factors engineers and researchers will use these definitions for research and design, consequently providing a more consistent and comparable evaluation processes.
