Simulation is a critical pillar in the testing and validation of autonomous vehicles (AVs), yet traditional methodologies often present a trade-off between realism and controllability, leaving much to be desired in replicating the complex dynamics of real-world driving. This limitation not only hampers AV development but also doubts the reliability of simulation-based validations. Recent advancements in data-driven diffusion models offer a promising avenue for bridging this gap by generating traffic scenarios that closely mirror real-world conditions. However, these models often overlook the intricate web of multi-agent interactions that AVs must navigate, a critical aspect that profoundly influences safety and operational efficiency.
This research aims to transcend these limitations by developing a data-driven diffusion model that elevates realism and controllability in simulations and intricately models the complex interactions between multiple agents for safe planning.
