We propose a new model in the analysis of car traffic flow phenomena, which in particular refers to a bus route, namely a closed path embedded in the urban network of roads. The model consists in a scalar balance law for the (macroscopic) density of cars, with source terms representing incoming and outgoing roads (with respect to the bus route), and a coupled systems of ODEs describing the dynamics of (microscopic) buses along the route. The coupling takes into account both the buses as moving bottlenecks in the car flow, and the effect of the car flow on the buses' ODEs as microscopic vehicles. The resulting fully coupled micro-macro model promises to give an appropriate description for the car flow as well as for the buses. Finally we study the model numerically.

Abstract

We propose a new model in the analysis of car traffic flow phenomena, which in particular refers to a bus route, namely a closed path embedded in the urban network of roads. The model consists in a scalar balance law for the (macroscopic) density of cars, with source terms representing incoming and outgoing roads (with respect to the bus route), and a coupled systems of ODEs describing the dynamics of (microscopic) buses along the route. The coupling takes into account both the buses as moving bottlenecks in the car flow, and the effect of the car flow on the buses' ODEs as microscopic vehicles. The resulting fully coupled micro-macro model promises to give an appropriate description for the car flow as well as for the buses. Finally we study the model numerically.
