The study was conducted to determine the effect of delineating the median storage area of the intersection of a four-lane highway with a two-lane highway on the operational safety of that intersection. Colored pavement was used to provide a color contrast between the median storage area and the through lanes of travel, thus delineating the median storage area for a motorist on the side road. A secondary objective was to develop a method of providing a nighttime visibility to the color in the pavement. The results of the study indicated that given the degree of delineation provided by the colored pavement, the delineation of the median has no effect on the operational safety or on the operational efficiency of the intersection. A satisfactory method of providing adequate nighttime visibility to the color in the pavement was not found.
