Abstract:

The purpose of the research effort was to develop and field test a unique color and shape coding system which offered promise as a supplement to conventional guide signing on problem interchanges. Following a review of the technical literature, a series of laboratory studies was conducted to empirically identify the most appropriate color and shape combinations for symbol signs. The symbol signs were used in various ways in the design of five color/shape coded route guidance systems which were installed and subjected to field evaluation on problem interchanges. With the exception of the initial system evaluated, all other systems resulted in operations and safety benefits as evidenced by a statistically significant reduction in erratic maneuvers and a significant improvement in other operational measures. It was concluded that the color/shape coding concept as applied to freeway route guidance results in sufficient benefit to merit further development and testing of such systems. This volume presents: a summary of the laboratory studies; a detailed description of the systems evaluated along with the results. Also included are guidelines for system design and implementation.
