Hi @eyth.alison et al.,
I downloaded 2017 onroad representative counties from EPA ftp
and CDB from
and found the representative counties are not consistent in the xlsx spread sheet and in the CDB
Here are some examples:
in the CDB we have 08014, 08099, 08123 as representative counties for Colorado
However, these three counties are not the representative counties based on the spread sheet
also if we look into Maryland
24023 and 24033 are not in representative counties spread sheet, but they are listed in CDB. 24021 and 24035 are in representative counties spread sheet, but they are not listed in CDB
And we know the VMT and VPOP CDB for representative counties are the VMT and VPOP for the entire group, so how can I use the VMT and VPOP in CDB for 8014, 8099, 8123, 8035, 8043, 8031.
And how to handle the CDB for Maryland.
Also, representative counties in PA, NC, RI are not consistent between data and spreadsheet as well.
