Abstract:A series of studies evaluated the Gateway configuration of R1-6 in-street signs. A
Gateway configuration consists of an R1-6 sign on the centerline, an R1-6 signs on both edges of
the roadway, and R1-6 signs on the lane lines if it is a multilane road. The Gateway treatment
was markedly more effective than the use of signs only on the centerline or on lane lines. The
results showed: 1. That yielding was related to the narrowness of the gaps between signs; that a
Gateway configuration consisting of R1-6 signs was markedly more effective than a Gateway
made up of blank signs of the same size and background color. Research also demonstrated that
mounting edge signs on the curb face was nearly as effective of placing signs in the gutter pan,
and that the use of a robust delineator in place of the R1-6 signs on the lane lines was almost as
effective as the use of the R1-6 signs on lane lines. This study also examined the efficacy of the
Gateway on different types of crosswalk applications, the long-term persistence of effects and
sign survival.
