In my experience, some types of one-way streets are some of the least trustworthy for crossing on foot because drivers treat them as race courses or interstates with speed limits (and sometimes worse, traffic lights) as barely a suggestion. It's interesting how much excitement as a pedestrian I find at the elimination of one-way streets and replacement with calmer two-way street "diet" patterns. (Street "diets" reduce lanes, add more dedicated turn lanes, smarter medians and parking.)
