Keep up the good fight, Jarrett.

There is another way to show that the TTI "congestion" ratings are crazy. Because they measure the difference between "free flow" and rush hour speeds, a city could get a perfect rating by slowing down "free flow" traffic speeds. Set speed limits to 15 mph on city streets and 30 mph on the motorways, and even New York would be "congestion free", based on this metric: the speeds at midnight would be just as slow as at rush hour.

Well done!

I guess this means the Globe and Mail is not interested in improving its journalistic standards? Or did they post a clarification that the story confused commute times (total travel time for all users) with a measure of how much faster a car commute is at uncongested periods versus peak periods?
