The has evidence that modern urban planners create more traffic congestion so that they can profit by building more congestion causing infrastructure by cynically selling it to the public as a way to relieve congestion.
"The Brooklyn Bridge could carry 426,000 people a day in 1907, but only 178,000 in 1988, according to former city traffic commissioner Sam Schwartz. "
"Conversely, some experts believe, removing roads does not make congestion worse. In the late 1990s, Transport for London studied a number of major roads -- including the West Side Highway in the 1970s -- that were taken out of service. While traffic engineers predicted chaos, little resulted."
If removing some roads doesn't make congestion worse, building them in the first place didn't make it better. Building them just made profit for the contractors who built them. Here in the DC area they want to widen a road, I-66. I went to a meeting on the project where the highway traffic modelers were present. After the meeting I got to talking to them about their studies. The were positive that increasing the lanes on the road would increase the total travel time for all travelers affected by the change. From what I recall the increased delay came from two causes. The extra lane would result in more interference due to more lane switching at the DC end, and by pushing cars from the highway into DC at a higher rate the cars from the highway would interfere with the movement of cars in DC that never use the highway but are trying to cross the city.
I think the road builders take advantage of Braess's Paradox to drum up more business. When I owned a car I planned 50 minutes for a certain trip, (between Alexandria and Potomac Mills for those who know the area) on weekends. A few months ago a friend who lives a few miles closer, (outside the beltway and outside the fairfax county parkway for locals) told me that it is now much longer than that from their house. How can that be? When I owned a car the Fairfax county parkway hadn't been completed neither had the Prince William parkway, both roads were sold to the public to relieve congestion along the very route. Now that both those roads are built, surprise, surprise, congestion is worse. Guess what? Gotta build more roads, gotta widen those roads, maybe replace the bike routes with car lanes.
