Abstract
En 中文
• Models grid-based trajectories as both spatiotemporal images and static graphs. • Fuses local and global patterns via parallel CNN and GAT encoders. • Eliminates reliance on external road networks via semantic feature injection. • Integrates Contrastive Learning and MLM for robust self-supervised training. • Achieves SOTA performance on travel time estimation and classification tasks.
