Macroscopic and multi-scale models for multi-class vehicular dynamics with uneven space occupancy: a case study
Maya Briani, Emiliano Cristiani, Paolo Ranut
In this paper we propose two models describing the dynamics of heavy and light vehicles on a road network, taking into account the interactions between the two classes. The models…
Angle dependence in coupling conditions for shallow water equations at canal junctions
Maya Briani, Gabriella Puppo, Magali Ribot
In this paper we propose a numerical Riemann problem solver at the junction of one dimensional shallow-water canal networks. The junction conditions take into account the angles wi…
Evaluation of emissions and ozone production due to vehicular traffic via second-order models
Caterina Balzotti, Maya Briani, Barbara De Filippo +1
The societal impact of traffic is a long-standing and complex problem. We focus on the estimation of ozone production due to vehicular traffic. For this, we couple a system of cons…
Understanding Mass Transfer Directions via Data-Driven Models with Application to Mobile Phone Data
Alessandro Alla, Caterina Balzotti, Maya Briani +1
The aim of this paper is to solve an inverse problem which regards a mass moving in a bounded domain. We assume that the mass moves following an unknown velocity field and that the…
Convergence rate of Markov chains and hybrid numerical schemes to jump-diffusions with application to the Bates model
Maya Briani, Lucia Caramellino, Giulia Terenzi
We study the rate of weak convergence of Markov chains to diffusion processes under suitable but quite general assumptions. We give an example in the financial framework, applying…
Understanding Human Mobility Flows from Aggregated Mobile Phone Data
Caterina Balzotti, Andrea Bragagnini, Maya Briani +1
In this paper we deal with the study of travel flows and patterns of people in large populated areas. Information about the movements of people is extracted from coarse-grained agg…
