\nThe Texas Transportation Institute today released another one of its periodic reports on traffic congestion. This one ranked the DC area first in delay per car commuter. The last report, in 2012, came under considerable criticism for its flawed methodology, and the new one doesn’t seem to have changed much, though its author sounds a little more sophisticated about possible solutions.

In Denseopolis, people live within 2 miles of work on average, but the roads are fairly clogged and drivers can only go about 20 miles per hour. However, it only takes an average of 6 minutes to get to work, which isn’t bad.
