[CTPP] Adjusted Urbanized Area

"The Federal Highway Administration approves adjusted urbanized-area boundaries that include the census-defined Urbanized Area plus transportation centers, shopping centers, major places of employment, satellite communities and other major trip generators near the edge of the Urbanized Area, including development expected to be in place shortly." Our state (Oklahoma) is conducting this exercise currently with all towns in Oklahoma. I am trying to find out more about this practice. Can someone point me to the federal register/the directive related to this? - Is the sole purpose here is to get the HPMS representation right or should we know more about the usage in apportionment. - What are the limits of such 'smoothening' the urbanized area by the above definition? - Is this intended for all towns/cities (both in and outside of the TMA?) - When the DOT 'smoothen' the boundary I assume they should include block group if they decide to go out and any other parameters one should be aware of? Thanks. Viplav Putta INCOG
