  Predicting the plausible future trajectories of nearby agents is a core
challenge for the safety of Autonomous Vehicles and it mainly depends on two
external cues: the dynamic neighbor agents and static scene context. Recent
approaches have made great progress in characterizing the two cues separately.
However, they ignore the correlation between the two cues and most of them are
difficult to achieve map-adaptive prediction. In this paper, we use lane as
scene data and propose a staged network that Jointly learning Agent and Lane
information for Multimodal Trajectory Prediction (JAL-MTP). JAL-MTP use a
Social to Lane (S2L) module to jointly represent the static lane and the
dynamic motion of the neighboring agents as instance-level lane, a Recurrent
Lane Attention (RLA) mechanism for utilizing the instance-level lanes to
predict the map-adaptive future trajectories and two selectors to identify the
typical and reasonable trajectories. The experiments conducted on the public
Argoverse dataset demonstrate that JAL-MTP significantly outperforms the
existing models in both quantitative and qualitative.
