DC Leading Pedestrian Interval
Very hard to make out in these pictures, but I stumbled upon a Leading Pedestrian Interval in DC at this intersection near Dupont Circle. it looks like the Walk is provided a 4 second advance based on my single cycle observation and delays the green from coming up in both directions to allow pedestrians to establish their presence in the intersection. DC uses a 100-second cycle length and this is a two-phase intersection, so it is an easy location to make this happen within the constraints of the intersection (which didn't seem that busy).
