- Abstract: In this technical report, we present the 2nd place solution of 2023 Waymo
Open Sim Agents Challenge (WOSAC)[4]. We propose a simple yet effective
autoregressive method for simulating multi-agent behaviors, which is built upon
a well-known multimodal motion forecasting framework called Motion Transformer
(MTR)[5] with postprocessing algorithms applied. Our submission named MTR+++
achieves 0.4697 on the Realism Meta metric in 2023 WOSAC. Besides, a modified
model based on MTR named MTR_E is proposed after the challenge, which has a
better score 0.4911 and is ranked the 3rd on the leaderboard of WOSAC as of
June 25, 2023.

Motion prediction is crucial for autonomous driving systems to understand complex driving scenarios and make informed decisions.
In this paper, we propose Motion TRansformer (MTR) frameworks to address these challenges.
The initial MTR framework utilizes a transformer encoder-decoder structure with learnable intention queries.
We introduce an advanced MTR++ framework, extending the capability of MTR to simultaneously predict multimodal motion for multiple agents.
