ITDP wrote up case studies of 8 relatively new car-free (or very car-light) neighborhoods in Europe, with scales ranging from a few hundred to tens of thousands of people, and how they compare to adjacent, similar communities, in terms of transportation mode share, etc. It’s great to see developments like this happening outside of the 500 year old city centers where cars really can’t be squeezed in without destroying the district. The urban density required to do this and make it work really isn’t all that high. Two developments each in Germany, Sweden, and the Netherlands, one outside London, and another in Switzerland.
ITDP has released a standard by which to measure the quality of a BRT system (in PDF form). It also does a pretty good job of explaining (as a stand-alone document) what it is that makes BRT different from normal bus service.
