Heterogeneous Graph Neural Networks for End-to-End Traffic Assignment and Traffic Flow Learning

arXiv:2310.13193v2 Announce Type: replace
Abstract: The traffic assignment problem is one of the significant components of traffic flow analysis for which various solution approaches have been proposed. However, deploying these approaches for large-scale networks poses significant challenges. In this paper, we leverage the power of heterogeneous graph neural networks to propose a novel data-driven approach for end-to-end traffic assignment and traffic flow learning. Our model integrates an adaptive graph attention mechanism with auxiliary "virtual" links connecting origin-destination node pairs, This …
