Pareto-optimal coupling conditions for the Aw-Rascle-Zhang traffic flow model at junctions
This article deals with macroscopic traffic flow models on a road network.
More precisely, we consider coupling conditions at junctions for the
Aw-Rascle-Zhang second order model consisting of a hyperbolic system of two
conservation laws. These coupling conditions conserve both the number of
vehicles and the mixing of Lagrangian attributes of traffic through the
junction. The proposed Riemann solver is based on assignment coefficients,
multi-objective optimization of fluxes and priority parameters. We prove that
this Riemann solver is well posed in the case of special junctions, including
1-to-2 diverge and 2-to-1 merge
