• Abstract:
  This report summarizes research activities regarding the delineation of concrete safety-shaped barriers (CSSBs) in situations where the barrier is located close to the travel lane. Included in this report are a summary of current barrier delineation practices in Texas; review of past CSSB research; discussion of results of field studies of CSSB delineation treatments on urban freeways in Austin and Houston, TX; and discussion of several mechanisms suggested for cleaning CSSB delineators. Field study results at alighted urban freeway site in Houston suggest that some delineation treatments may have a small effect upon the distance at which drivers travel from the barrier as compared to a no-delineation condition under nighttime dry-weather conditions. However, it was not possible to determine whether this effect is of practical significance in terms of traffic safety and operations.
