Abstract

We reproduce the capacity drop phenomenon at a road merge via point constraints in a first order traffic model. We first construct an enhanced version of the locally constrained model introduced by Haut, Bastin and Chitour in [1], then we propose its counterpart featuring a non-local constraint and finally we compare numerically the two models by constructing an adapted finite volumes scheme. These results are part of an ongoing collaboration with Edda Dal Santo (Univ. dell’Aquila), Carlotta Donadello (Univ. de Franche-Comté) and Massimiliano Daniele Rosini (Univ. di Ferrara).
