>>"We shall only used the official government classification system of the roads,"

As can be seen in this study:
https://www.iasj.net/iasj/article/184845
page no. 101 (5th page), which specify all classifications of Sader City main streets according the Mayoralty of Baghdad, primary roads were maped based on it, along with my local knowledge of the city.

>>"Were this research published or discussed?"
the research output is the proposal itself, again all Baghdad were mapped based on it, you have a problem with it, then all Baghdad need to be changed.

>>"you changed many many road classifications, just last 3 days you made this changeset and those other changesets 152559788, 152559016, 152558508, 152558069 etc.. You has tens or even hundreds of changesets when you changed road classifications"

First you claimed that "I changed almost all the secondary roads in Baghdad to primary," 
First of all, all roads I've changed to primary are in Sader City exept two. secondly, Here is the list of all roads I changed to primary, which some weren't even secondary:

1- شارع الداخل (tertiary to primary).
2-شارع ابن الهيثم (tertiary to primary).
3- شارع الجوادر (half already was primary, other half was secondary).
4- شارع زين القوس (secondary to primary).
5-شارع الشيباني (secondary to primary).
as I stated, you're exaggerating.
