Three different areas of roadway delineation were included in this study. These areas were:

  1. Lane delineation materials,
  2. crosswalk delineation materials, and
  3. snowplowable markers.

Evaluation of lane delineation materials revealed that expanded use was warranted for polyester paint and extruded thermoplastic. The alkyd-resin extruded thermoplastic material was determined to be the most cost-effective material for crosswalk and stop bar installations. Durability and reflectivity results show that Stimsonite 96 markers have performed effectively as snowplowable markers while the recessed markers have performed effectively except on certain interstate locations.
