Seeing through the eyes of a self-driving car: visualizing autonomous vehicle data on the web

Submitted Jun 14, 2018

The ATG (Advanced Technologies Group) at Uber is shaping the future of driverless transportation. Over the last two years, the ATG Visualization team built a web visualization platform that enables engineers and operators across ATG to quickly inspect, debug, and explore information collected from offline and online testing. In this talk, we dive into the challenges of combining complex and diverse datasets into a reusable and performant web application, and how Uber’s open-source visualization tech stack brings it to life.


  • Data visualization at Uber: the many visualization tools, and why they are crucial to the business
  • Introduction to ATG
  • Overview of the autonomous vehicle data: what is in there, and why it’s hard to visualize
  • Designing a visual language for the decision making process of a self-driving car
