The Federal Highway Administration (FHWA) has begun a number of initiatives to improve signing on the Nation's roadways. These include workshops to obtain input from experts across the country, a review of each State's highway sign replacement and refurbishing program, and a training course. This report documents the proceedings of the workshops, one held in the Western United States and one in the Eastern United States. The workshops opened with a plenary session on Issues, Needs, and the FHWA Research Program, followed by a plenary session on Development of Minimum Requirements. The program continued with a panel discussion on Performance Standard Criteria, followed by a plenary session on Materials Selection. Breakout sessions on freeway signing, non-freeway signing, and motorist services and tourist-oriented signing completed the first day of the workshops. The second day opened with reports of the breakout sessions and continued with a plenary session on Field Assessment Techniques. A plenary session on Maintenance Procedures and Programs followed. The second day ended with breakout sessions on sign replacement methods, using contracting versus in-house and prison industries, and traffic control during sign replacement. The third day opened with reports on the previous day's breakout sessions, followed by a plenary session on Improved Inventory Techniques. The workshops closed with a Look to the Future plenary session. This report details the remarks made by the panelists and the comments and concerns of the participants on each of these issues.
This synthesis will be of interest to traffic engineers, planners, and others interested in making sure that motorists' needs for directional information on freeways are being met. Information is provided on policies and procedures used by states in evaluating freeway guide signs and replacing those that are outdated or deteriorated. Many signs on freeways and other controlled-access highways have exceeded their service life and are no longer serving motorists' needs. This report of the Transportation Research Board describes the policies, proceduress, and criteria used by states for freeway sign evaluation and replacement programs.
