Hello all,

I wanted to share a small civic data project I've been quietly working on since last year...

(the dataset)

This is a continuously-growing, open, versioned dataset of road traffic conditions across a set of pre-determined Bangalore routes, each roughly 10km long. The premise is simple – it asks Google Maps "how long do you think it takes to get from point A to point B?" The data has been accumulating twice an hour, every hour of every day for about 8 months now. The goal was to build a cheap-to-maintain, easy-to-manage, transparent, trustworthy, open, public traffic dataset for research and civic engagement. 

In the past month, I've also built an app on this dataset, which makes the data highly accessible and usable. https://co.thecontrarian.in/

trafficOracle lets you compare current travel speeds against historical patterns. You can even go back in time to see what the traffic was like on a given day at a certain time. It's a powerful dashboard with no backend, nothing to install, fully open source. I'd love for members here to poke around, raise issues, and more importantly, adapt it for other cities anywhere in the world.

Happy to answer any questions!

Regards,
Mahesh
