High-occupancy vehicle lanes can help incentivize carpooling (and let solo drivers sit in punishing congestion). But too often, transportation agencies spend millions of dollars to widen the road to make carpool lanes, instead of simply designating existing lanes. To recoup some of the expense, the agencies also let drivers pay to use the new "high-occupancy/toll lane."

Kaid Benfield's new blog post on density is getting a lot of buzz over at NRDC's Switchboard blog. Benfield, a planner/lawyer/professor/writer who co-founded both LEED's Neighborhood Development rating system and the Smart Growth America coalition, has some serious street cred when it comes to these matters. And on this one, he's with Danish architect Jan Gehl, who says wonderful places are built at human-scale density -- three to six stories.

Jeff is back from Rail~volution with all the highlights from the sessions he skipped because he was deep in conversation in the hallways. Isn't that what conferences are for? We discuss what we do and don't get out of these big meetings.

How much traffic does a transit line keep off the streets? Looking at ridership alone only tells part of the story, according a new study published in the Journal of the American Planning Association. The full impact of a transit line on motor vehicle traffic can far exceed the direct effect of substituting rail or bus trips for car trips.

A recent report by U.S. PIRG and the Frontier Group, “Highway Boondoggles: Wasted Money and America’s Transportation Future,” examines 11 of the most wasteful, least justifiable road projects underway in America right now. Here’s the latest installment in our series profiling the various bad decisions that funnel so much money to infrastructure that does no good. 

Transit advocates around the country were transfixed by a story in Tennessee this April, when the state chapter of Americans for Prosperity made a bid to pre-emptively kill Nashville bus rapid transit. It was an especially brazen attempt by Charles and David Koch's political network to strong-arm local transportation policy makers. But it was far from the only time the Kochs and their surrogates have taken aim at transit.

Consider this a bonus track. A deleted scene at the end of your DVD. Extra footage.

Dramatically expanding transit and active transportation over the next few decades could reduce carbon emissions from urban transport 40 percent more than following a car-centric trajectory. And it could also save the world economy $100 trillion.
