The newest Toronto Transit Commission (TTC) map is distorted - and so are most transit maps. Network diagrams usually replace traditional maps when navigating people through a system, which favours connectivity over geographic accuracy.

I was always curious, when looking up at the TTC's subway map, what it actually looked like. I ended up recreating it to scale one day and was surprised by the response.

Since the TTC is updating the map, I thought I would take another look at it, but with some analysis this time. Using Bernhard Jenny's MapAnalyst I was able to create a deformation grid over top of the subway map.
