BenRossTransit, I'm half-way through Wes Marshall's Killed by a Traffic Engineer. A terrific book, very readable despite the inherently dry subject matter, and lots of information new to me as someone who has given the topic a lot of attention. (Still, I have to admit it isn't competing well for my attention today against the Stormy Daniels testimony.) https://islandpress.org/books/killed-traffic-engineer#desc
