The release of the new UAs has inspired a lot of questions about their effects on transportation planning and programming. The FHWA has a couple of good web pages on FAQs: Specifically for UZA and UC http://www.fhwa.dot.gov/planning/census/faqa2cdt.htm And a couple of layers up, but a broader swatch of transportation planning http://www.fhwa.dot.gov/planning/census/ Happy hunting!
