Katie DJ is the first free traffic data broadcast. In other words, is a web platform that streams data related to road network traffic (e.g., number of vehicles in the streets). Such data are open and accessible to everyone.

  • No registration is required.
  • No email is asked.
  • No information at all is asked: data is simply broadcast to the world and anyone can "listen to" (read, download) it.

What, Why, How?

Please refer to the Frequently Asked Questions at http://www.katiedj.com/#faq. Furthermore, if some question of yours is not answered there then we encourage to get in touch with us. The easiest way to do so is to open a ticket/issue in Katie Dj repository.

Download the data

We release open-source clients that handle connection and data download from Katie DJ. You are not forced to use our clients (you can write your own), but using ours should save you time. We plan on releasing clients for the most common "scientific" programming languages. At the time of this writing, only the Python3 client has been released.


External contribution is definitely welcome, in any form. Please do no hesitate to send to us your opinion about Katie DJ, your ideas about some additional feature. Furthermore, you can fork this repository to work on different ideas, or you can submit a merge request if you think we should integrate something of yours.

For any enquiry about feature requests or bug report please open a ticket/issue in this report.
