BITS: Bi-level Imitation for Traffic Simulation. (arXiv:2208.12403v1 [cs.RO])

Simulation is the key to scaling up validation and verification for robotic
systems such as autonomous vehicles. Despite advances in high-fidelity physics
and sensor simulation, a critical gap remains in simulating realistic behaviors
of road users. This is because, unlike simulating physics and graphics,
devising first principle models for human-like behaviors is generally
infeasible. In this work, we take a data-driven approach and propose a method
that can learn to generate traffic behaviors from real-world driving logs. The
method achieves …
