Two studies were conducted to determine the visibility and comprehension of pedestrian signals. A video questionnaire was developed to study the comprehension of innovative and standard pedestrian crosswalk devices. Results indicated that green and red are interchangeable in meaning with white and orange, respectively. A red 'slash man' appears to be a strong alternate to a symbolic orange hand. It was recommended that a three-phase pedestrain signal be considered that would incorporate the strengths of green, yellow, and red with innovative symbols. The study on the visibility of actual pedestrian signals determined that a minimum signal intensity of 25 cd is adequate for any pedestrian signal regardless of technology, distance, signal size, text, or symbol.
