Data for this challenge comes from multiple traffic cameras from a city in the United States as well as from state highways in Iowa. Specifically, we have time-synchronized video feeds from several traffic cameras spanning major travel arteries of the city. Most of these feeds are high resolution 1080p feeds at 10 frames per second. The vantage point of these cameras is for traffic and transportation purposes and the data will be redacted in terms of faces and license plates to address data privacy issues. Moreover, we have built a synthetic vehicle data set consisting of over 1,300 distinct vehicles and over 140,000 images. These synthetic images will form an augmented training set to be used along with the real-world traffic data set for Tracks 2 and 3.
