Abstract
This study evaluated whether a driver's intention to comply with a stop sign, and/or negotiate a turn, or proceed on a straight path could be predicted through the identification of patterns in driver input to vehicle primary controls. Driver input to primary controls was assessed during intersection approach, according to type of intersection manoeuvre. Control input patterns, relative to intersection arrival, were used to identify effective timing of driver alerts and warnings regarding potential hazards at an intersection. The results of the study will support the development of countermeasures to prevent or reduce the severity of intersection crashes. (A)
