How do drivers react in locations where centerline rumble strips are used in passing zones?
In a recent Texas Transportation Institute study, passing operations before and after the installation of CRSs was studied along a 15-mile stretch of two-lane rural highway. The researchers demonstrated that there were no erratic maneuvers before or after the centerline rumble strips were installed. Erratic maneuvers were defined as rapid alignment changes, overcorrection, or wrong corrective actions in a trajectory. An example of a wrong corrective action would be a driver initially moving farther to the left rather than to the right when the driver inadvertently contacted the centerline rumble strips. The study concluded that “Neither erratic nor avoiding maneuvers were observed at the centerline rumble strip installation site.
