Updated 2 April 13, 2014 at 2:50pm: Eric Miller, the author of the illustrations originally used for this article, has objected to their being taken out of context and has asked that they be removed.
Meanwhile, the information is available in a paper by Dr. Miller of February 24, 2012 which is available on the City of Toronto’s website. This is cited in a City Planning presentation at the Sheppard Transit Corridor Expert Panel on March 2, 2012.
I am hoping to obtain new information about Scarborough travel patterns from a regular reader. When this is available, I will update the article.
In another thread’s comments, I mentioned that I would post travel pattern info for Scarborough to show how this behaves.
The diagrams linked here were originally produced by Eric Miller at the UofT, and they have been included in a few presentations including one recently at the UTSC Eco-Summit by André Sorensen. The source data come from a 2006 survey conducted by the University on behalf of governments in the GTHA. More recent data are about to be published, but they were not available when these charts were created.
There are two pairs of charts in this set, one for the planning district north of the 401, and one for the district to the south. For each district, both the AM Peak and All Day flows are shown.
North of the 401 (Planning District 16), 36% of the travel is within the district, and a further 19% is to the area south of the 401. Only 6% of the travel is to downtown. During the AM peak, the percentage to downtown doubles, but other demands are comparable (on a percentage basis) to the all day values.
South of the 401 and west of Kingston Road / Morningside (Planning District 13), there is a slightly higher proportion of trips going downtown, but the lion’s share remains within Scarborough and to other suburbs.
There are a few caveats about these charts.
- There is a typo on the first chart where there is a reference to internal trips within PD13. This should of course refer to PD16.
- The values shown are percentages, not absolute numbers.
- There is no information for south-eastern Scarborough.
I’m not excusing the shortcomings, just saying these are the charts I have available. Once the updated data come out, it will be intriguing to see how this has evolved (and not just for Scarborough) and to attach numbers to the percentages.
The basic point is that although, yes, there are many people who go downtown from Scarborough, there are many more who are travelling to some other location, and their transit requirements should not be forgotten.
Updated April 13, 2014:
In response to comments asking about the context of the travel charts, a fifth page has been added showing a sample of corridors on which LRT could be implemented to form a network in Scarborough. Note that this map is part of the presentation from which the others are taken, and it is not “my” map. Moreover, it is “descriptive” in the sense of “this is what could be done”, not “prescriptive” in the sense of “you must built exactly this network and nothing else”. Comments in the vein of “why here and not there” will be deleted as I really don’t want to get into a hypothetical discussion of a network here.
