The area that stretches between the property line on one side of a street and the property line on the other side of a street is called a public right-of-way here in Toronto. It may be called something different in other cities and countries.

In the example below (taken from Toronto's Avenues & Mid-Rise Buildings Study), it includes the sidewalks, the car lanes, and the streetcar lanes. But it could also include other public elements. In this instance, the buildings on either side of the street are assumed to be built right up against their property lines.

ROWs obviously serve an important public function. But their size also has important urban design implications. As a pedestrian, it feels different to walk on a narrow street than it does on a broad street.

The width of a ROW can also be used to inform what the preferred height of the buildings along it should be. In the example above, they’re talking about a 1:1 relationship between the width of the ROW and the preferred height of the buildings.

Given their importance, I thought it would be interesting to share this map of Toronto (dated 2010) showing ROW sizing throughout the city. The mustard colored lines in the core of the city represent 20 metres, the red lines 36 metres, and the purple lines 45 metres or more. The rest of the colors fall somewhere in-between. For the most part, the purple lines represent highways, although there are a few other instances of purple.

What’s interesting – but not surprising – to see is how we basically kept expanding the size of our ROWs as Toronto grew outwards. This was obviously to make more room for cars on the road.

But the other, perhaps more interesting thing about this map, is that it could also serve as a guide to pedestrian happiness. The mustard/yellow lines are where it’s most enjoyable to walk. And the red and purple lines are where it’s least enjoyable to walk.

If you’re from Toronto, give this framework a try and see if it holds true.

In anticipation of our new streetcars beginning service this Sunday, the Globe and Mail published an article on Friday called: Why Toronto is still a streetcar city. And I was quoted as saying the following:

I had no idea that I was going to be cited, but I like the quote that was chosen. The key words are: “when done well.” There are a myriad of different ways in which a city can implement streetcars, and each will have varying degrees of performance.

So if you’re one of those people who are critical of streetcars, I would encourage you to think about streetcars not just in terms of how they’re implemented today in Toronto, but also in terms of how they could be implemented going forward.

All streetcars lines are not created equal.

Earlier this month the Toronto Star published an article talking about the resurgence of streetcars in American cities. According to the Star, 89 cities in the US are currently implementing or at least considering building some form of surface-rail system.

But the article also goes on to argue that it could be a snobbish fad. Streetcars are new. They’re shiny. And they make yuppies –  who don’t like taking buses – feel better about themselves. But is the ROI really there? Is the economic impact of streetcars as big as people are making it out to be?

To support this argument, the Star quoted transportation planner Jarrett Walker, who I’ve mentioned here before on Architect This City. But according to a follow-up post that Walker did on his blog
