I posted this chart on Twitter last night. It's from the WSJ showing new weekly confirmed COVID-19 cases in Florida, New York, and the U.S. as a whole. Now, the first thing I will say is that I relinquished my hopes of becoming an amateur epidemiologist back in April. I have no idea how this is all going to play out. But as an urbanist, it is interesting to note that back in April, many believed that New York City's urban density was a real problem and the almost singular cause of its high number of cases (despite many other big and dense cities around the world doing much better). There was also a belief (or hope) that warmer temperatures might have a positive impact on transmission rates. That's maybe why Florida was doing relatively better. But things have flipped. Cases in Florida are up and California just surpassed NY for the US state with the most number of cases. So who knows what will happen next. But what I do know is that wearing a mask isn't a big deal (I have mine with me all the time) and that big urban centers will be just fine. City Observatory recently published apartment search data suggesting that dense cities have actually been getting more, rather than less, attention in the wake of COVID. That doesn't surprise me.

Door handles are a funny thing these days. They are one of if not our most common point of contact with the built environment, and yet in the best of times they go largely unnoticed. And in today's world they have flipped to become a source of anxiety. Do I really need to touch this door handle or can I maybe use my foot or elbow? Some have responded by wearing gloves. But sometimes door handles offer up clues -- such as a worn finish -- as to where they are most commonly touched. But then one is faced with yet another difficult dilemma: do you handle the pristine part or remain committed to the worn out part since everybody else is probably thinking what you're thinking and searching for the unadulterated section of the handle? Who knew that opening a simple door could elicit such complexity.

But we shouldn't be too critical of the mighty door handle. Edwin Heathcote recently published this short history of door handles and it's a good reminder of the design intent that has gone into them over the years and how they also came to embody our broader views about architecture. One of my favorites, of course, is the original Bauhaus door handle designed by Walter Gropius and Adolf Meyer c. 1922. (Pictured above, it's currently housed on the fifth floor of the MoMA in New York.) Its lever starts out square and machine-like, but then transforms into a cylinder, exactly where you're supposed to grip it with your hand. It is ultra minimal, but it tells you exactly what to do. It also helps us with our dilemma. Worn or not worn, the cylinder is obviously where it should be handled.

In Toronto we have a street named Avenue Road. If you're learning about this for the first time, you might be wondering: "Well, is it an avenue or is it a road?" Then again, does that sort of distinction even matter? Does it imply certain characteristics? When I think of an avenue, I think of a broad and straight tree-lined street. And indeed, Avenue Road is connected to a street called University Avenue, which is pretty straight, broad, and has trees lining it. It's a ceremonial kind of street that leads you toward the Ontario Legislative Building. It fits my definition. And so maybe Avenue Road is really saying, "Yeah, I know I'm not an avenue in the traditional sense, but I eventually connect into one and so I have decided to use both names."

It could also be the case that we haven't always been that meticulous when naming our roads. Or perhaps we simply changed the way we designed and thought about our streets as we sprawled outward, and along with that came some name changes. In the oldest parts of Toronto, the main streets tend to be exactly that -- streets. And our secondary streets are often named as avenues. This is the opposite of a place like Manhattan, where avenues are the broad north-south streets that take you downtown and uptown, and streets are the smaller east-west roads that take you across the narrower part of the island. Here there is a very clear logic. Avenues are big. Streets are small.

Looking at this road name map of London by Giuseppe Sollazzo (click here if you can't see it above), it's obvious that London's street network is pretty much the opposite of New York's rational street grid. But you can see what appears to be a clear graduation from streets (in the center) to roads and then to some sort of melange that seems to include a bunch more avenues. They may just be street names, but they to speak to a whole host of things, including the evolution of our cities, changing attitudes toward city planning, and naturally the adoption of new kinds of mobility. They also make for nerdy maps.
