For critics of widening projects, the prime example of induced demand is the Katy Freeway in Houston, one of the widest highways in the world with 26 lanes.
Immediately after Katy’s last expansion, in 2008, the project was hailed as a success. But within five years, peak hour travel times on the freeway were longer than before the expansion.
Matt Turner, an economics professor at Brown University and co-author of the 2009 study on congestion, said adding lanes is a fine solution if the goal is to get more cars on the road. But most highway expansion projects, including those in progress in Texas, cite reducing traffic as a primary goal.
“If you keep adding lanes because you want to reduce traffic congestion, you have to be really determined not to learn from history,” Dr. Turner said.
Especially since most exits have very easy U Turn options. Just get off at the next one and then turn around
Not all of them. If someone tries to ram you and you get off on the wrong exit to avoid the crazy person at 5pm on a Tuesday you can lose an hour and a half of your life over a distance of 7 miles.
Don’t ask how I know.
Oh I’m well aware. I missed an exit once so I just kept going, and the next one happened to be one of the few that was just a winding road and took me far away.
