My hometown, Greenwich, Connecticut, has already done this in central downtown. No joke, rain, sleet, snow or shine, from 7 am to 8 pm, there are cops that direct traffic at all the intersections in the central part of town. Some people have said that maybe traffic lights would be a better solution, but the locals all feel that somehow, this adds to the character of the town. And if pedestrians ever cross the street when they're not supposed to, they get a stern lecture from the traffic cop.
