UNSTAGGERED CENTRAL SCHEMES FOR ONE-DIMENSIONAL NONLOCAL CONSERVATION LAWS

2024Open accessMohamed I University

Abstract

We describe a new family of second-order, unstaggered central finite volume methods for one-dimensional nonlocal traffic flow models.The main advantage of the presented method is its ability to evolve the numerical solution on a single grid, avoid solving Riemann problems at the cell interfaces, and alternate between an original and a staggered grid.Our numerical results demonstrate the effectiveness and performance of the suggested method by comparing them favorably to those produced using the original Nessyahu-Tadmor (NT) method.
