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.

Last week The National Post published an article talking about Toronto's Crosstown LRT and how it’s spurring a wave of development all along Eglinton Avenue. Below is a map, taken from that article, showcasing some of the developments that are currently in the pipeline and awaiting the Crosstown’s opening date of 2020.

Not surprisingly, developers like transit investment. But more specifically, they like fixed track transit investment. Rarely do new bus routes elicit the same sort of response that you’re seeing above. And that’s because fixed track investment has permanence. If you’re going to go long on an area, you want certainty.

As the Crosstown tunnel boring machines move across midtown Toronto, I thought it would be interesting to look at a transit concept that I first learned about through Jarrett Walker’s Human Transit blog. It’s called: the radius of demand. 

One of things that transportation planners look at when designing and building a new line is the spacing of stops. Typically, as you move from buses all the way up to subways, the spacing between stops and stations increases. Spacing is always a bit of a trade off though, because more stops means easier access for riders, but it also means slower overall service. Somewhat famously, Paris designed its metro system so that you’re rarely more than 500 meters away from a station. 

Once you have your station locations, it’s quite common to then draw a radius around each stop to simulate the catchment area. In other words: How much of the city can I service with this station and how far will people be willing to walk in order to get there? However, this distance, which is the radius of the circle, usually depends on the type of transit. Oftentimes people are willing to walk further in order to get to faster transit service.

Last weekend a friend of mine sent me an article from The Economist talking about why trams, streetcars, and light rail are a waste of money. The argument is basically that steetcars are expensive, less efficient, and that – despite North America’s renewed interest in them – we should instead be spending our scarce public dollars on more buses.

Here’s a snippet from the article:

…but cash spent on streetcars displaces spending on other, more cost-effective forms of public transport like buses, which offer cheaper and more-efficient service but are considerably less sexy. The capital cost per mile of a streetcar is between $30m and $75m, while a rapid bus service costs anywhere between $3m and $30m, according to the American Public Transportation Association.

Now, there’s no question that buse routes are initially cheaper to implement. You don’t have track to build. But I don’t agree that the cost structure is quite that simple if you consider the number of people you need to move in your city. I struggle to see buses as a more efficient service.

The big difference between modern light rail and buses is capacity.
