A new study from the University of Toronto clearly shows that additional free road capacity — either from adding actual road, or shifting people from driving to transit — has no effect on congestion. Traffic expands to fill the available capacity, no matter how much you add, and the net public benefit from the investment in additional road capacity is negative.

- When shared cars kill
Peer to peer carshare cars are killing people, because cars of any kind kill people... not because they're shared. They're big and heavy and fast, and they get operated in densely populated areas. Anybody who thought this wouldn't come up when they started setting up these services was delusional. The thing I don't really get is why on earth is the owner of the car liable for an accident involving it? Assuming the car didn't spontaneously explode due to poor maintenance, I presume the death and destruction is a consequence of bad driving, texting, drinking, poor road engineering, etc. Just - Carsharing saves city governments millions
Migrating city fleets to car-sharing has been able to reduce the size of those fleets by 50-75%, and increase vehicle utilization from 30 to 70%, which means way less in the way of city capital costs dedicated to cars. It also means a lot of policymakers getting much more familiar with the sharing economy. - A French-Canadian bicycle moving company
Tips on How to do a Bike Move from Déménagement Myette, a commercial bicycle moving company in Montreal. They have a whole fleet of extra wide Bikes at Work cargo trailers, that carry standard household appliances with ease! More than 1000 bike moves done since 2008. - How Google’s Driving Costs Misses the Train
A fun critique of the estimated driving costs that you get from Google Maps, from Alex Steffen. The costs of driving are largely (mostly?) systemic, and external to the individual, and predicated on an assumption of car ownership, and a mile-for-mile interchangeability between driving trips and walking/biking/transit trips, which is empirically wrong. People who don't rely on cars for transportation do the same things in far fewer miles (3 to 9 times fewer, depending on the urban fabric they are embedded within). - Fourmile Creek Failure
Yesterday the Boulder Greenways Advisory Committee killed the Fourmile Creek Path because of objections from the NIMBYs living near the right-of-way. Separated off-street infrastructure that's available year round is vital to getting kids on bikes, and seeing them as a real mode of transportation. Political will is essential to build for the future even when the nearby and present interests are opposed. Without some backbone here, we're never going to get a transportation system that isn't wholly dependent on fossil fuels, or streets that are built for human beings.
