Perhaps cite an example of that phenomena in Alberta? I suspect you can't because our population hasn't reached the level where this occurs.

In each of the two years before the Glenmore/Elbow/5th St interchange opened, the average annual daily traffic on Glenmore between Macleod and Elbow was 81,000 vehicles a day. In each of the two years since the interchange opened, the AADT in the same location was 94,000 vehicles per day. That's a 16% increase on a road not located near any new development, and it's from a stable level both before and after; i.e. it's not a trend, it's the new capacity being filled up as it was created, i.e. it's induced demand.
Also, it's not like planners are some sort of mythical half-lion half-badger creature that only survives in climate-controlled pods. They're people who also live in the city. So they're
both end users and planners.
