The Power Broker by Robert Caro, a biography of Robert Moses that's particularly focused on his long career in the government of New York, is, quite aside from a fascinating psychological portrait and a parable about how bad it is when someone has untrammeled power in a bureaucracy, an absolutely fantastic case study in how building more roads makes traffic worse. And it was published in 1974! For anyone that cares to find out we've know this for decades and have absolutely failed to do anything about it - pretty depressing.
Caro has a way with words; one of my favorite turns was when Moses declared traffic a problem "solved for a generation", only for Caro to begin the next paragraph with a description of the traffic jams that began to develop a few weeks after that particular road (I believe the Bronx River Parkway) opened.
Seconded - I'm currently listening to the audiobook of this book and I find it utterly fascinating.
Yeah, the reader of the audiobook is pretty good, although I slightly prefer Grover Gardner, who recorded the audiobooks for his series on LBJ, as a narrator. If you like The Power Broker, I'd highly recommend those.
