Transverse grooves were installed at 11 intersection approaches on worn rigid pavement to reduce a high rate of wet-road accidents. In most cases, accident reductions were experienced only at intersections with multiple negative operational characteristics, including higher approach speeds, limited sight distances, and frequent vehicle stopping for turns or stop signs. Intersections with no more than one negative characteristic generally did not benefit from grooving.
