Abstract
A raised pavement markers removal vehicle system and method for the removal of raised pavement markers from a roadway. As the vehicle is driven along a roadway, a grinder unit alongside the forward portion of the vehicle grinds away the raised pavement markers to be removed. A sensing unit senses the relative lateral positions of the grinder unit and the upcoming raised pavement markers to be removed. A controller receives position information from the sensing unit and sends appropriate commands to an alignment adjuster to match the lateral position of the grinder unit to the lateral position of the upcoming pavement markers to be removed. After removal by grinding, the debris from the removed raised pavement markers is swept from the roadway into a sweeper-hopper unit for transport to a suitable unloading place. A warning board mounted at the rear of the sweeper-hopper unit provides a visual warning to other users of the road.
