Decomposing Traffic Flow Patterns Under Extreme Weather: A Novel Field-Theoretic Framework Using Discrete Differential Operators, Xuhui Lin, Qiuchen Lu, Yi An, Tao Yang, Junqing Tang
CIB Conferences
Extreme weather events increasingly challenge urban transportation systems, requiring advanced methods to understand and predict traffic adaptations. Traditional graph-based approaches to traffic analysis, while effective for static conditions, struggle to capture the continuous and dynamic nature of flow patterns during weather disruptions. Current methods lack the mathematical framework to bridge discrete network structures with continuous flow dynamics, particularly in analyzing how traffic patterns reorganize under stress. This paper presents a novel field-theoretic framework for analyzing traffic flow patterns, integrating Hodge decomposition with continuous field visualization. The framework decomposes traffic flows into three fundamental components: gradient flows representing direct movements, curl …
