Improving highway information at hazardous locations : seven case studies : summary of Demonstration Project No. 48. Prepared for the Office of Traffic Operations and the Office of Highway Opreations, Federal Highway Administration FHWA

This report summarises the results of Demonstration Project No. 48 - Application of the Positive Guidance Process. The Positive Guidance process is designed to analyse a hazardous location's safety and/or operational problems and develop low-cost, short-range information system solutions. The demonstration project was begun in 1978 and completed in 1984. Its objectives were to: (1) Apply Positive Guidance to range of situation; (2) Demonstrate its effectiveness; (3) Improve the safety and/or operations of the sites; and (4) Provide inputs to upgrade the Users' Guide to Positive Guidance (lst Edition). A total of $625,000 was allocated for seven projects in Washington (2 projects), Michigan, New Jersey, Georgia, California, and Iowa. Five of the seven projects were fully successful in achieving the objectives, and the remainder were partially successful. Information and feedback from the projects was used to develop the 2nd Edition of the Users' Guide to Positive Guidance. It was demonstrated that Positive Guidance was applicable to locations requiring short-range low-cost information system solutions to safety and/or operational problems. (Author/publisher)
