HetroD: A High-Fidelity Drone Dataset and Benchmark for Autonomous Driving in Heterogeneous Traffic

ICRA 2026poster

We present HetroD, a dataset and benchmark for developing autonomous driving systems in heterogeneous environments. HetroD targets the critical challenge of navigating real-world heterogeneous traffic dominated by vulnerable road users (VRUs), including pedestrians, cyclists, motorcyclists, and vehi…

Learning to Drive is a Free Gift: Large-Scale Label-Free Autonomy Pretraining from Unposed In-The-Wild Videos

CVPR 2026

Ego-centric driving videos available online provide an abundant source of visual data for autonomous driving, yet their lack of annotations makes it difficult to learn representations that capture both semantic structure and 3D geometry. Recent advances in large feedforward spatial models demonstrat

SPACeR: Self-Play Anchoring with Centralized Reference Models

ICLR 2026poster

Developing autonomous vehicles (AVs) requires not only safety and efficiency, but also realistic, human-like behaviors that are socially aware and predictable. Achieving this requires sim agent policies that are human-like, fast, and scalable in multi-agent settings. Recent progress in imitation lea…

LANGTRAJ: Diffusion Model and Dataset for Language-Conditioned Trajectory Simulation

ICCV 2025poster

Evaluating autonomous vehicles with controllability enables scalable testing in counterfactual or structured settings, enhancing both efficiency and safety. We introduce LangTraj, a language-conditioned scene-diffusion model that simulates the joint behavior of all agents in traffic scenarios. By co…

Editing Driver Character: Socially-Controllable Behavior Generation for Interactive Traffic Simulation

RA-L 2023

Traffic simulation plays a crucial role in evaluating and improving autonomous driving planning systems. After being deployed on public roads, autonomous vehicles need to interact with human road participants with different <italic xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://w
