Some concern has been raised over the use of identical rumble strip patterns on both the left and right side of the roadway. Preliminary findings from the simulator research indicated that driver's response to centerline rumble strips was sometimes different than the desired reaction; some drivers encountering the SRS pattern/spacing on the centerline corrected to the left, potentially creating a hazardous situation. There is evidence to suggest that drivers have developed an a priori expectancy related to shoulder rumble strips that may carry to centerline rumble strips. This research focused on evaluating existing rumble strip patterns and spacing, complemented with the development of a unique centerline arrangement that is easily understood, eliciting a single-conditioned-automatic-correct response from the driver, while considering other locational criteria, that will ideally lead to a reduction in the number of cross-over centreline and associated fatalities.
