We always use highway=trunk for National Highways, regardless of if its a dual carriageway or not. For divided roads, you can always add dual_carriageway=yes. This allows routers to properly prioritize driving on National Highways, which are typically faster and better maintained than State Highways. It also makes it easy to differentiate highways on the map visually.

No worries, you can refer to the wiki in the future for reference: osm.wiki/India/Tags/Highway

Hi, I see you have reclassified the roads as primary. These are designated National Highways (NH966) and should be classified as `highway=trunk`, as they were before

Hi, as mentioned in the last changeset comment, this road is a designated National Highway. It should be classified as trunk. Please do not reclassify it

Hi, could you please stop adding access=no on all footpaths? It is completely redundant and actually messes up cycle routing, as mentioned previously. Also it would help if changesets are more local, rather than having changes that affect small roads across three cities

Hi, I noticed that NH766EE has been misclassified as tertiary. It should be classified as a trunk highway, as it was previously. The road has a ref tag too. Please revert to the previous classification

Hi, thanks for catching that, it was supposed to be building:levels=10

Hi, I'm curious, why was the road surface deleted? It is correct to the best of my knowledge

Hi, I see you reclassified NH352A as motorway from trunk. While it is access controlled, it does not have the motorway Vienna convention sign, which is why I had reclassified it to trunk. In my opinion a more appropriate tag would be highway=trunk + expressway=yes, since highway=motorway would have legal implications (in India its not permissible for cycles/bikes/mopeds to use expressways with the motorway sign, as per MORTH). There is a relevant discussion on the community forum: https://community.openstreetmap.org/t/classifying-expressways-in-india/123387/11

Also wiki link for Indian road classification, which I updated recently based on the community forum discussion: osm.wiki/India/Tags/Highway

Hi Bitsu, I'm not sure on what "evidence" these edits were made. 1. footways do not need `access=no`, with foot=yes. This is implicit in highway=footway. 2. We don't need horse access tags. 3. These ways are designated cycleways. Removing `bicycle=designated` is blatantly incorrect. These kinds of incorrect edits with regards to access are impeding cycle and pedestrian routing in the city. Please do NOT change access tags on footways and cycleways unless there is actual signage in contradiction to the existing OSM tags. I have reverted these changes.

Hi,

National Highways should always be classified as highway=trunk, in this case the airport approach road is supposed to be NH166S, so it should be a trunk road. The new classification as secondary is incorrect.

Hi, thank you for the change set. I see you re-classified NH785 as motorway. I had classified it as trunk because it doesn't use the standard signage to indicate its a motorway. It is simply a flyover on top of an existing road. There is a discussion here on reclassifying "expressways" in India here: https://community.openstreetmap.org/t/classifying-expressways-in-india/123387

Hi, this road does not exist. There is no such road present. At best there are two tracks, but neither are motorable or permanent. Both are used only by heavy construction vehicles.

Hi, this way is not "superfluous", I had even left a note stating as much. Please do NOT edit features with out checking the notes field first.

Hi, this road is a bridge over the road below it, it was correctly tagged before. Please do not delete bridges without reviewing the area.

Hi, this link was not "superfluous", it exists on the ground, and is used daily. The note explicitly states that, please review notes before modifying ways.

Hi, thank you for the edit, but link roads like this would be better tagged with highway_link=*. This is definitely not a residential road

Hi, this road should be tagged as trunk_link since it is a slip road between ORR and Hosur road. Further, 1st Main doesn't have connectivity to ORR, this road has been barricaded off for a very long time now.

Hi, thank you for your edits. I noticed you have upgraded significant parts of the road network to highway=motorway, but it doesn't look like the correct tag in this case, since none of these roads are fully grade separated/access controlled. highway=trunk would be the desired classification for National Highways that are not grade separated or access controlled

Hi, thank you for your changeset. I believe this road should be tertiary since it serves a thoroughfare function, and it is an urban road in the RMP as well. Based on this the previous tertiary classification was accurate.
