|This one. A plague upon the idiot inventor of this sign.|
The only time an intersection is not a legal crosswalk is if it is specifically marked with one of these signs. Circumstances when this sign makes sense do exist--for example, there's an intersection I cross at least twice a week where the street goes from two-way traffic to one-way traffic, and there's a "no pedestrian" sign on the two-way side. (But not, it should be noted, on the cross street, where the traffic is two-way in both directions, so... huh?) The argument can be made that this intersection already has sufficient confusion for motorists that taking out one leg of pedestrian crossing makes it a touch easier. To which I say: meh. If that's what it takes, I suppose, but these situations are rare and as such, the signs should be used sparingly.
However, I'm pretty sure Cincinnati got a bunch of these signs in a sale and just puts them up whenever they have a traffic crew sitting around bored for a few minutes. ("Here, y'all run out and put up one of these signs. Doesn't matter where.") I see them in high-pedestrian areas all the time, which makes no sense--why force more people to cross the street just to cross the street?

Take down most of those dumb signs and get serious about really protecting pedestrians, Cincinnati. There are plenty of ways to make a city a better place for pedestrians, but this is not one of them.
