Reduced visibility on the highway due to darkness and adverse weather conditions results in an inability of motorists to readily observe pavement markings. Because raised pavement markers provide increased pavement and roadway delineation, the feasibility of using them has been investigated by the Research Council and the results are summarized in this report. Also, because of the increased use of raised pavement markers by the Department, recommendations for the placement of the markers have been developed and are presented.
