You may have added the address incorrectly. You have added `addr:housenumber=24 Rajkrisna Ghosal Road`, here it seems like 24 should be the house number and Rajkrishna Ghosal Road the street. In that case the correct tagging should be
...
addr:housenumber=24
addr:street=Rajkrishna Ghosal Road
...

In this changeset you added a name "Gramshalika - Moregram Rd via Kuli" to a road. According to the convention of OSM naming, we do not add abbreviations of words in the `name` tag. Also, I don't think the "via ..." part should be included in the name.

I feel like there are many issues with your edits for Bus station. The addr tags does not have proper values and it is clearly not a building.

As far as I understand, the naming convention in OSM discourage abbreviations such as Rd, for road. It name should have the full word "Road" instead of Rd.
Also, although I couldn't see the whole thing clearly as I was in the car, but the street sign clearly uses the word Road. So I hope you or someone from the Ola team reviews these.

A lot of your edits in this changeset doesn't use the proper tagging scheme. Please correct. Also would be nice if you had better changeset comments instead of a bunch of hashtags.

Your edit for this building has a lot of conflicts and the shape is not mapped quite correctly. As you can see, the building crosses over a street.. If you don't mind, I would like to correct the feature with your help.

In this and some other changeset, you have use the `name` tag to what seem to be `addr:housenumber` tag; e.g. `name=174`. I feel like this tagging scheme you are using is incorrect.

I have noticed that in some railway platforms you have used `highway=steps` in combination with `bridge=yes`. Is that the correct convention?

Just so there is no confusion, this is only for the way that I gave linked above in my first comment.

From my experience at the location, the road is too narrow for a 4 wheeler but pedestrians regularly using that road. Bicycle and motorcycle are allowed. The road is lined with houses on both sides. In my opinion `highway=pedestrian` or `highway=service + service=alley` with additional tags for access is how we should tag this place.

One of the road tagged as `highway=unclassified` is wrong. The road is not wide enough for a car. And the tag should reflect that.

Your use of `highway=primary` seemed odd to me. Can you please explain why you tagged it as such?
