This study evaluated the effects of R1-6a pedestrian crossing signs, installed in various configurations, on driver yielding behavior at uncontrolled marked crosswalks across six Oregon locations. The research analyzed both staged and naturalistic crossings under different experimental conditions, including baseline, tubular markers, single and multiple R1-6a signs, and gateway installations. Video data were coded to assess crossing volumes and yielding rates for over 5,900 pedestrians. Baseline yielding was already high, averaging 85% nearside and 89% farside, but increased further with sign treatments. The gateway configuration achieved the highest yielding rates of 92% (nearside) and 97% (farside), while curb-top edge sign placement produced 87% nearside yielding and 99% farside yielding. These findings demonstrate that R1-6a signs, particularly in gateway configurations, enhance driver yielding even when baseline compliance is high, though variations across sites highlight the influence of differing roadway contexts and pedestrian environments.
