No question the grid system works much better than a freeway/arterial system. Too much traffic has to funnel into one place rather than being spread evenly across the grid. The best traffic situation in Calgary is in the north central area, which is a grid lacking any freeways.

Having said that, Calgary still functions well as a spread out city because its employment is so concentrated (no employment sprawl), parking is so expensive and we've managed to create a relatively good rapid transit system (that is about to get a couple billion dollars better).

Remember, density is not an end in and of itself.
