: By using intelligent roadside infrastructure, cities can create real-time HD maps that are more accurate than those generated by individual vehicles alone. Common Tools and Research
: Self-driving cars rely on these maps to "see" beyond their immediate sensors, helping them predict lane paths and understand complex signal patterns. IntersectHD
: Emerging technologies use these data-driven maps to improve safety by predicting potential collisions between vehicles and pedestrians. : By using intelligent roadside infrastructure, cities can
Traditional maps used for navigation (like standard GPS) provide general routing, but offer centimeter-level accuracy. For intersections—the most complex and accident-prone areas of a road network—this involves detailed semantic mapping. Traditional maps used for navigation (like standard GPS)
: A tool used by engineers to programmatically build 3D scenes of intersections for automated driving simulations.
Traffic signal locations and their corresponding stop lines. Pedestrian crosswalks and sidewalk transitions. Static objects like curbs, poles, and barriers. Why is it Important?
