The Torc self-driving car not only conquered daytime driving in the snow, it also traveled on a variety of routes at night during one of the biggest snowfalls of the winter. In this clip, Asimov navigates autonomously around a traffic circle at night. Our team uses multiple methods in perception and navigation to allow the system to know where lane lines are on the road, even though the markings are covered in a blanket of snow. This allows Asimov to perform the necessary lane changes to stay on its planned route through the circle.
