How about this?



1) Proper expressways. Mumbai-Pune, Ahmedabad-Vadodara and a few bypasses bult by nhai: motorway

2)Upgraded national highways. at least 4lane divided with shoulders. gq, nsew etc. most of them fall in the nhdp project http://en.wikipedia.org/wiki/NHDP: trunk

3)Upgraded nh's, 2lane with shoulders. like the nh4 between chitoor and kolar, nh67 mangalore-hassan: Primary

4)other nh's. single lane: Primary

5)upgraded sh. 4lane divided, like the banglore-mysore highway: Primary/trunk

6)other sh 2/1 lane : Secondary

7) district roads: Tertiary

8) others/rural roads between villages: Tertiary

I wonder if the day will ever come when the country will have a widespread expressway network. so in addition to (1) i think we can also tag (2) between tollbooths as motorways, as these are pretty high speed highways anyway. i think almost all tolled roads are high speed roads (>80kmph), right?

Anything else that is non-tolled and atleast 4lane divided can be trunk. (3) and (5) fall under that


(4) is primary

(6) is secondary

everything else tertiary?

  Good idea. These are the kind of roads we have:

  8) others/rural roads between villages

  We need to devise one tagging system within metropolitan areas and one outside metropolitan areas.

  That isnt an NHAI map btw, its mine ;)

    Can we can baseline the tagging based on color codes given on the NHAI map- http://upload.wikimedia.org/wikipedia/commons/f/f7/India_simplified_roadway_map.svg (big file)

    Even 10,000 active mappers wont be enough to update the status of roads frequently. how many mappers would you expect who travel by road on 60000kms of national highways daily? While this can be done on heavily used nh's like the golden quad etc but its an impractical approach to follow for all the roads. I agree thats its really useful for motorists to know the condition of the road, but it would require a huge and highly unsustainable effort.

    This is the kind of info that i would like to see as an overlay to the map, like how you have live traffic status in google maps. That said, i'm not telling you not to continue your work with nh67, but it would be impossible to replicate this approach on our huge network of highways whose length total more than 200,000kms (nh+sh).


    I'm planning to give a session on osm at barcamp chennai this saturday, so it would be great if we can agree on something by then.

    cheers

      not dedication - I travel these roads every day. So can update the condition
      daily. Which is the case with all of us - we maintain our areas. Currently
      there are about 10-12 active people in India, but soon there will be
      thousands - in that case daily updates of road conditions is possible. That
      is why we are better than google

      We all agree on expressways - no problem

      1. Trunk - connecting major cities. So we have to agree on major cities:

      metros - Mum, Chen, Del and Kol (maybe also bengaluru and hyderabad)

      2. Primary - connecting 2 tier cities to each other and to major cities

      2 tier cities: coimbatore, pune, madurai, mangalore, ahmedabad ...

      3. Secondary - connecting district headquarters to state capitals or other
      district headquarters

      4. Everything else tertiary or less

      This is regardless of who owns the road

      Within cities - just map using common sense - basically, size of the road and
      amount of usage.
