“…Participants with smooth and sustained steering manoeuvres have lower average steering wheel angle peaks (Salvucci & Liu, 2002) whereas drivers who implement sharp and quick steering manoeuvres generate higher steering angle peaks. Previous analyses of steering strategies have found high between-participant variability (Salvucci & Liu, 2002) and also that steering wheel angle profiles differ dependent on the bend geometry (Gabrielli, Paganelli, Schiro, Pudlo, & Djemai, 2012). In the current experiment only a single road-line was visible, and without the full road context (i.e.…”

Vehicle control by humans is possible because the central nervous system is capable of using visual information to produce complex sensorimotor actions. Drivers must monitor errors and initiate steering corrections of appropriate magnitude and timing to maintain a safe lane position. The perceptual mechanisms determining how a driver processes visual information and initiates steering corrections remain unclear. Previous research suggests two potential alternative mechanisms for responding to errors: (i) perceptual evidence (error) satisficing fixed constant thresholds (Threshold), or (ii) the integration of perceptual evidence over time (Accumulator). To distinguish between these mechanisms an experiment was conducted using a computer-generated steering correction paradigm. Drivers (N=20) steered towards an intermittently appearing ‘road-line’ that varied in position and orientation with respect to the driver’s position and trajectory. One key prediction from a Threshold framework is a fixed absolute error response across conditions regardless of the rate of error development, whereas the Accumulator framework predicts that drivers would respond to larger absolute errors when the error signal develops at a faster rate. Results were consistent with an Accumulator framework, thus we propose that models of steering should integrate perceived control error over time in order to accurately capture human perceptual performance.

“…Participants with smooth and sustained steering maneuvers have lower average steering wheel angle peaks (Salvucci & Liu, 2002) whereas drivers who implement sharp and quick steering manoeuvres generate higher steering angle peaks. Previous analyses of steering strategies have found high between-participants variability (Salvucci & Liu, 2002) and also that steering wheel angle profiles differ dependent on the bend geometry (Gabrielli et al, 2012). In the current experiment only a single road-line was visible, and without the full road context (i.e., both road edges) drivers may have been more likely to vary in their steering strategy.…”
