ROADWAY DELINEATION SYSTEMS
ROADWAY DELINEATION TREATMENTS AND SYSTEMS ARE SPECIFIED AND INSTALLED TO AID DRIVERS IN CONTROLLING THEIR VEHICLES, THEREBY IMPROVING THE SAFETY ASPECTS OF THE HIGHWAY AND EASING THE DRIVING TASK. THERE IS A LOGICAL PROCESS BY WHICH INSTALLATION DECISIONS HAVE BEEN AND ARE BEING MADE. THE INFORMATION DEVELOPED IN THIS RESEARCH PROJECT PROVIDES MEANINGFUL AND USABLE MEANS TO STRENGTHEN THE DECISION PROCESS AND ENHANCE THE LIKELIHOOD OF COST-EFFECTIVE SOLUTIONS. A COMPREHENSIVE STATE-OF-THE-ART SUMMARY COVERING THE APPLICATION OF VARIOUS DELINEATION TREATMENTS TO HIGHWAY SITUATIONS, DELINEATION MATERIAL PROPERTIES, THE HUMAN FACTORS LITERATURE PERTINENT TO DELINEATION, AND COST EFFECTIVENESS CONSIDERATIONS WAS COMPILED. EMPHASIS WAS GIVEN TO CURRENT PRACTICES - PARTICULARLY DEPARTURES FROM THE STANDARD MANUALS, - AND RECENT RESEARCH FINDINGS. PRACTICES AND RESEARCH RESULTS OF OTHER COUNTRIES WERE INCLUDED. SEVEN TASKS WERE SET FORTH TO SERVE AS THE RESEARCH FRAMEWORK: (1) REVIEW PAST AND CURRENT RESEARCH; (2) PREPARE A STATE-OF- THE-ART SUMMARY; (3) DETERMINE THE DRIVER'S DELINEATION REQUIREMENTS; (4) ESTABLISH RATIONAL TECHNIQUES FOR DETERMINING THE EFFECTIVENESS OF DELINEATION TREATMENTS; (5) TEST PROMISING DELINEATION SYSTEMS; (6) DEVELOP PRACTICAL CRITERIA FOR THE SELECTION OF DELINEATION TREATMENTS; AND (7) EVALUATE COLORED PAVEMENTS. LABORATORY AND FIELD STUDIES WERE CONDUCTED. RECOMMENDATIONS FOR THE APPLICATION OF THE VARIOUS TREATMENTS AT EACH OF THE "CLASSICAL" SITUATIONS WERE DRAWN UP ON THE BASIS OF THESE STUDIES, DISCUSSIONS WITH OTHER RESEARCHERS AND PRACTICING ENGINEERS, AND REVIEW OF THE LITERATURE. EIGHT PRINCIPAL CONCLUSIONS WERE DRAWN.
