Bad Data: “How Not To Measure Traffic Congestion—Hold the Hyperbole, Please! “

The INRIX report makes several other basic errors. It describes traffic congestion as “gridlock,” a greatly abused term. Gridlock refers to a specific situation in which vehicles in a network are totally stuck due to clogged intersections. It almost never occurs.

I’ve only just started following Litman.  I should have followed him sooner, I think.  I can’t imagine that gridlock has actually ever happened in Oklahoma.

Interesting: “A second life for the state’s highway overpasses”

Who knew?

Article: A second life for the state’s highway overpasses – Metro – The Boston Globe.

When I lived there, numerous overpasses had “additional support” from large timber beams.  It was really bad.

I see that they did a maintenance blitz  — http://www.massdot.state.ma.us/highway/HighlightedProjects/93Fast14RapidBridgeReplacementProject.aspx — and got some of the ones I used to cringe under … I mean drive under back in the day.   They have other bridge replacement projects on-going.

The article above is not about that, though.  While it’s even better when elevated roadways are taken down, like they did with the old Central Artery and are planning to do with the McGrath Highway (not to mention many others including OKC’s Crosstown), this at least makes them less ugly and/or scary.  That’s a good thing, IMHO.
