Sections of grooved and painted traffic stripes were evaluated for visibility under various conditions at three locations: In a mountainous area elevation at about 6000 feet where heavy snow is prevalent in winter, in a foothill area where no snow is expected, and in the valley also where no snow is expected and where the terrain is very flat. It was concluded that a grooved stripe is not a satisfactory solution to the problem of lane line delineation in snow plow areas, and where no snow is expected, the raised marker type line is best.
