PENNSYLVANIA'S GUIDE RAIL STANDARDS: A COST-EFFECTIVE CHANGE

In 1985, the Pennsylvania Department of Transportation implemented a systematic technique to inventory the condition and location of guide rail and median barrier along Pennsylvania's highways. This process has been developed to supplement the Department's Systematic Technique to Analyze and Manage Pennsylvania Pavements (STAMPP), the foundation of the Department's total Roadway Management Information System. A major recommendation of the task force which developed the guide rail inventory was to review the Department's guide rail standards and warrants which are both cost-effective and safe. A special task force, comprised of District, County and Central Office personnel reviewed other states' criteria and research reports and consulted with a number of state and federal officials. The AASHTO cost-effectiveness approach which is detailed in in AASHTO's "Guide to selecting, locating, and designing traffic barriers" was then utilized to develop guide rail warrants which are both cost-effective and safe. The task force also recommended several other changes to the Department's guide rail standards which will result in a more efficient use of resources without compromising the safety of the roadside environment. This report outlines the recommended changes and the procedures used. (Author)
