As to 440/460m "too far" I also wonder how people manage to do that in other cities such as NYC or Boston.
I didn't say that 440/460m is "too far", I said that it's "too far for the first round of stop rationalization". In other words, let's start removing the stops that bring the stop spacing within our target of 300-400m before we start talking about increasing that target to 400-500m.
And without further ado, here are those stops:
You'll note that many of these were already identified by the TTC in the aforementioned
stop rationalization report. But many of them are not.
I've bolded a few stops that I particularly dislike due to their impact on streetcar progression:
Queen & Victoria: We've already talked at length about this stop.
Spadina & Richmond: This stop is right in the middle of a green wave for motor traffic, which means that when streetcars stop they get out-of-sync and then face very long signal delays. Yet if they didn't stop, they'd just cruise through a lot of the time.
Bathurst & Adelaide: Southbound streetcars routinely get stuck in the queue of cars turning left onto Adelaide, while other vehicles simply pass using the other lanes. Obviously the solution is to spread the streetcar tracks to create a left turn lane, but in the meantime, removing the stop would allow us to make the Transit Signal Priority a lot more effective. This is one of the few intersections where it is possible to go directly from the straight through green signal to the left turn signal on the same street without creating a dangerous situation called the "yellow trap". So we could pull up the southbound left turn signal ahead of any southbound streetcar to clear out the queue.
I emphasize that this is not the complete list of stops I'd remove, or even the complete list of stops the TTC plans to remove. Some stops resulting in >400 m spacing are still easy picking if there is a gap in trip generators (over the Don River for example), or if there is a narrow catchment area (Lakeshore & Lake, for example).
Methods:
To identify the stops I'd remove, I created my own 'ideal' stop network then spotted the differences.
Starting with the streetcar network, I first identified all the transfer locations. These would be the fixed points in the network. The remainder of stops could be moved around to optimize spacing, crossing facilities and proximity to trip generators.
Next I filled in the gaps. My target spacing was 300-400m, with all stops located at a pedestrian crossing facility (as per the TTC report). Areas with shallow catchment areas or few trip generators would err at the higher end of spacing (350-450m), and areas with denser pedestrian networks and more trip generators would err at the lower end (250-350m). There are unfortunately many locations where my ideal stop spacing is not possible due to the location of pedestrian crossings.
Finally I turned on the existing streetcar stops layer and picked out the ones that were not at one of my proposed locations. I have not noted the places where a stop is moved a block or two to line up with a signal or PXO since I figure these will happen anyway and they don't have much impact to speed or walking distances.
Tell you what. You find me the reference for what the TTC system-wide spacing is - rather than some number you've pulled out of your imagination.
According to page 3 of the the TTC streetcar stop removals report:
"The current average stop spacing on streetcar routes is approximately 250 metres."
I don't have a stat off-hand about bus routes, but they seem pretty similar.
