From Eric Sehr, here's a very clear schematic of the Frequent Network in Toronto -- covering the Toronto Transit Commission Area but not adjacent regions. If I were TTC, I'd just publish this as it is. Note how clearly you can assess where you can get to without much delay, and also note how well-connected the Frequent Network is.
For the full-size zoomable version, see here.this post, later expanded as Chapter 7 of my book Human Transit. Agencies that now market Frequent Networks include those in Montreal, Salt Lake City, Minneapolis, Vancouver, Spokane, and Seattle. Portland was once a leader until its Frequent Network was destroyed by budget cuts in 2009. For more -- including both advocate-made and a few agency-made Frequent Network maps -- explore the "Frequent Networks" category on this blog. As a consultant I provide advice on Frequent Network branding worldwide.
