Generalization Second Order Macroscopic Traffic Models via Relative Velocity of the Congestion Propagation

This paper presents a generalized second-order hydrodynamic traffic model. Its central piece is the expression for relative velocity of congestion (compression wave) propagation. We show that well-known models Payne–Whitham, Aw–Rascal and Zhang are all special cases featured model, their properties fully defined by how expressed. The proposed model verified with data from segment Interstate 580 freeway in California, USA, collected California DOT’s Performance Measurement System (PeMS).
