Working on a project to determine the speed limits of every road network within Metro Atlanta's boundary. I have GDOT RC data, Navteq/HERE data, ABM data made in-house, and Open Street Maps. These all differ a bit. Where can I find, or pull, the data to get closer to completion on my project?

Thanks

  • Could you confirm that the ABM data stands for Activity Based Model? Also, which version of ArcGIS do you have? – Daniel Miller Oct 17 '16 at 14:08
  • ABM is activity based model. It is ArcGIS 10.2.2. – Sigal Carmenate Oct 18 '16 at 19:52

You need to define a hierarchy of speed limits. The NavTeq/Here data will include all roadway databases; starting with this, then you can spatially join the data to the base network you create.

The key will be determining which database you "trust" more.
