Nonlocal balance laws–an overview over recent results

A Keimer, L Pflug - Handbook of Numerical Analysis, 2023 - Elsevier
In this contribution we give a short overview of recent advances in nonlocal conservation
laws. In these equations, we assume that the flux f is decomposable into f (x)= V (x) x, x∈ R …

Arbitrary high order central non-oscillatory schemes on mixed-element unstructured meshes

P Tsoutsanis, M Dumbser - Computers & Fluids, 2021 - Elsevier
In this paper we develop a family of very high-order central (up to 6th-order) non-oscillatory
schemes for mixed-element unstructured meshes. The schemes are inherently compact in …

An overview of non-local traffic flow models

FA Chiarello - Mathematical Descriptions of Traffic Flow: Micro, Macro …, 2021 - Springer
We give an overview of mathematical traffic flow models with non-local velocity. More
precisely, we consider conservation laws with flux functions depending on an integral …

Modeling multilane traffic with moving obstacles by nonlocal balance laws

A Bayen, J Friedrich, A Keimer, L Pflug… - SIAM Journal on Applied …, 2022 - SIAM
We consider a system of nonlocal balance laws where each balance law is coupled with the
remaining balance laws both by a nonlocal velocity function that takes into account the …

Numerical schemes for a class of nonlocal conservation laws: a general approach

J Friedrich, S Sudha, S Rathan - arXiv preprint arXiv:2302.07724, 2023 - arxiv.org
In this work we present a rather general approach to approximate the solutions of nonlocal
conservation laws. In a first step, we approximate the nonlocal term with an appropriate …

In this paper, we propose and analyze a reconstruction technique which enables one to
design high-order conservative semi-Lagrangian schemes for kinetic equations. The …

Conservative semi-Lagrangian schemes for kinetic equations Part II: Applications

SY Cho, S Boscarino, G Russo, SB Yun - Journal of Computational Physics, 2021 - Elsevier
In this paper, we present a new class of conservative semi-Lagrangian schemes for kinetic
equations. They are based on the conservative reconstruction technique introduced in [1] …

Network models for nonlocal traffic flow

J Friedrich, S Göttlich, M Osztfalk - ESAIM: Mathematical Modelling …, 2022 - esaim-m2an.org
We present a network formulation for a traffic flow model with nonlocal velocity in the flux
function. The modeling framework includes suitable coupling conditions at intersections to …

Nonlocal approaches for multilane traffic models

J Friedrich, S Göttlich, E Rossi - arXiv preprint arXiv:2012.05794, 2020 - arxiv.org
We present a multilane traffic model based on balance laws, where the nonlocal source term
is used to describe the lane changing rate. The modelling framework includes the …

Discontinuous nonlocal conservation laws and related discontinuous ODEs–Existence, Uniqueness, Stability and Regularity
