I am an in a University Level Intro to GIS class and we are begining to look at what we are doing for our final projects. I am mostly interested in Urban/Regional planning and of the New Urbanist/Smart Growth/Suburbia must die point of veiw. We use ArcGIS 9 and must demonstrate our ability to infer things from our maps and what not. Initially, I was planning on demonstrating how low population density does not mean low traffic density, but my prof said traffic density stuff is often expensive and hard to come by. So I was wondering if anyone either had that type of data they wanted to 'lend' me, or if any of you brilliant planning type people had any ideas. The school is in rural MN, I'm from Chicago, and like working with things I'm familiar with.
