Generally speaking, I see lots of parents with kids out and about near the vicinity of Sherman Circle. I also see a fair amount of dog walkers and general pedestrians until 9 or 10pm I’d say. After that there’s not a ton of pedestrian traffic, but then again it’s a residential area and not a lot to walk to at that time of night; so I can’t say it has anything to do with safety or perception of safety. I’d be interested in others’ thoughts on this too.
Also, my understanding is that lights will soon be installed in Sherman Circle so the circle itself will be better lit at night. That should help with safety, or at least the perception of safety.
