Trajectory prediction is a fundamental technology for advanced autonomous
driving systems and represents one of the most challenging problems in the
field of cognitive intelligence. Accurately predicting the future trajectories
of each traffic participant is a prerequisite for building high safety and high
reliability decision-making, planning, and control capabilities in autonomous
driving. Jedoch, existing methods often focus solely on the motion of other
traffic participants without considering the underlying intent behind that
motion, which increases the uncertainty in trajectory prediction. Autonomous
vehicles operate in real-time environments, meaning that trajectory prediction
algorithms must be able to process data and generate predictions in real-time.
While many existing methods achieve high accuracy, they often struggle to
effectively handle heterogeneous traffic scenarios. In this paper, we propose a
Subjective Intent-based Low-latency framework for Multiple traffic participants
joint trajectory prediction. Our method explicitly incorporates the subjective
intent of traffic participants based on their key points, and predicts the
future trajectories jointly without map, which ensures promising performance
while significantly reducing the prediction latency. Additionally, we introduce
a novel dataset designed specifically for trajectory prediction. Related code
and dataset will be available soon.
