Traffic Data for India

[Sudarshan RSA]

Hi everyone,

I'm trying to source traffic data for India to analyze as part of an economics paper relating to air pollution that I'm trying to write. What I want is, estimates of traffic density/an adjacent measure at as granular a level as possible and preferably at the daily level. One ideal configuration would be to have gridded daily data like we do with weather variables, but I suspect that will be difficult.

What is the best level at which I can find the sort of data I'm looking for? Google maps doesn't seem to have historical data for traffic. 

I seek your advice.

Sincerely,

Sudarshan

Hi Sudarshan 

Disclaimer: I haven't tried it and I'm only shooting in the dark.

Open street map (OSM) usually has archives of a lot of types of their data across the web. It also has a GPS navigation system similar to Google maps, so I'm assuming they would have archival data for traffic too. Maybe that's a place you could look.

If there are any other people who have concrete info on this, please pitch in. 

Thanks and regards.

Yours sincerely

One approach would be to look if someone is archiving historical GTFS data. (I saw something Nikhil VJ was doing for delhi a few years ago.) It has bus was here(lat-long) at this point of time data. With a lot of cleaning, I was once able to derive traffic (slow-fast) conditions for many roads during working hours.

Hi,

Rigved, thanks for the suggestion. Sudarshan, 

I've saved delhi gtfs-rt (bus gps locations) data over 2019-2020 (mostly 2019) here:

https://server.nikhilvj.co.in/delhirt/ 

you'll see some zipped csvs, one covering each week. (.7z is a zip format that gives good compression for text data, lookup 7zip)

Please feel free to use it as you may. Data is as-was in the realtime feed released by https://otd.delhi.gov.in/ .

Also, just to clarify Shiv's input : No, Openstreetmap doesn't have GPS navigation system and doesn't keep such archival data. That might be other apps using OSM. It has gps traces uploaded by users, for use as an aid for mapping. But most mapping doesn't rely too much on those now as there's better quality satellite imagery around now. They're likely not to repeat much along the same routes as the intention is to just one-time map a path.

Dear All,

Thank you very much for your assistance. Special thanks to Nikhil for the data and Rigved and Shiv for the flags. I now have a much better understanding of what the traffic data landscape looks like - this will should suffice for my project. I simply want to show that heightened air pollution solutions affect traffic in one way or the other.

Thanks again!
