Rolling Ahead Diffusion for Traffic Scene Simulation

Understand

Realistic driving simulation requires that NPCs not only mimic natural driving behaviors but also react to the behavior of other simulated agents.

• Recent developments in diffusion-based scenario generation focus on creating diverse and realistic traffic scenarios by jointly modelling the motion of all the agents in the scene.
• However, these traffic scenarios do not react when the motion of agents deviates from their modelled trajectories.
• For example, the ego-agent can be controlled by a stand along motion planner.
