I'm working on a project involving roads. The quality of the service would benefit from knowing if a given road is continuous or if it's broken up by stop signs, traffic signals, and other things that effect a motorist.
I haven't found anything googling around online. I also contacted my local city government, but they only grant access to the data for city projects. I'm guessing most areas would have similar rules.
Is there another source, public or commercial, that could help me out? Or am I out of luck?
EDIT - I should note that I'm looking for data in the USA.
