A recent X/Twitter thread began with a claim that the streetcar system suffers from slow operation because of closely spaced stops, specifically below 100 metres. I made a short reply showing the average spacing for each route, but have now generated charts showing all routes in detail.

There are only a handful of stops spaced closer to or below 100m, and so the claim that this is a source of much delay is easily disproved. The question then is what the typical spacings are, why, and how much “efficiency” could be obtained by eliminating some of them. I do not attempt to answer that question here, but simply present the actual stop spacing data so that there can be informed debate.

The TTC’s design goals for stops are set out in the Service Standards:

2.4 Surface Stop Spacing
Surface stops should be designed in accordance with the TTC’s Technical Criteria for the Placement of Transit Stops. When the locations of stops are being planned for a route, it is necessary to strike a balance between the competing objectives of passenger convenience, operating efficiency, safety and community impacts. In general, increasing the number of stops on a route results in shorter walking distances for passengers but it also slows down service. To achieve a proper balance, the TTC will place bus stops in accordance with the standard presented in Table 2 [below].

Service Classification	Stop Spacing Range
Streetcar	300 – 400 metres
Bus – Local	300 – 400 metres
Bus – Express (Tier 1)	650 – 1,000 metres
Bus – Express (Tier 2, Limited Stop)	650 – 1,000 metres
Bus – Express (Tier 2, Local/Express)	650m for express portion; 300 – 400m for local portion
Bus – Community	Flag stop

It’s important to remember that Toronto streets are not laid out on a repeating grid as in some cities, and one cannot simply stop at “every second street”, or whatever layout works. Existing pedestrian circulation patterns, transfer points, major origins/destinations all play a role in defining a “good” stop location. This is even more of a problem in suburban areas with longer blocks and poor opportunities to access transit stop from “nearby” (as the crow flies) neighbourhoods.

Methodology

The stop distances for each route have been taken from the GTFS versions of the schedules published regularly by the TTC. These are used by trip prediction and planning apps to understand the layout of the system. In a few cases where current operations do not match the historic route layout (e.g. 501 Queen, 504 King, 512 St. Clair), I have used older data sources from a period when routes operated normally.
