GUIDERAIL DELINEATION. FINAL REPORT
The objective of this study was to investigate the need to delineate guiderail and to evaluate the performance of different types of guiderail delineation. The effects of soil and dirt accumulation on guiderail delineators was measured in an effort to select the most suitable device for this purpose. The installation procedures for each type of guiderail delineation evaluated are discussed. Two surveys were conducted as part of this study. One survey documents how drivers characterize guiderail delineation. The second survey lists a nationwide summary of state practices in delineating guiderail. This study has determined that a flexible panel and metal bracket system is the most appropriate device for delineating W-beam guiderail with regard to durability, resistance to soiling, and ease of installation.
