crossing guard
A uniformed guard who directs traffic at crosswalks and intersections to allow pedestrians, often school children, to safely cross the road. Often wears a high-visibility vest and may hold a flag or stop sign.
Crossing guards are known by a variety of names. "Crossing guard" is the most common American and Canadian term. In the United Kingdom, Ireland, and Australia they are known as "lollipop ladies" or "lollipop men", after the large signs they carry that resemble lollipops. In New Zealand, they are known as as "school road patrol".
