🔥 Nexus is a noise-decoupled prediction pipeline designed for adaptive driving scene generation, ensuring both timely reaction⏲️ and goal-directed control🥅.

🌟 Nexus can generate realistic safety-critical driving scenarios by flexibly controlling the future state of a scene, with the assistance of NeRF.

Image description

Nexus-Data is induced from real-world scenarios, in which we can obtain real-world map topology and layout. It also includes hazardous driving behaviors through interactions introduced by adversarial traffic generation. The safety-critical scenarios (on nuPlan dataset) can be obtained through this 🔗data link.
