OSM vs HD Maps: Map Representations for Trajectory Prediction

no code implementations4 Nov 2023 Jing-Yan Liao, Parth Doshi, Zihan Zhang, David Paz, Henrik Christensen

While High Definition (HD) Maps have long been favored for their precise depictions of static road elements, their accessibility constraints and susceptibility to rapid environmental changes impede the widespread deployment of autonomous driving, especially in the motion forecasting task.
