Consider the following portion of urban network: Piazza Re di Roma, studied as graph composed by 24 arcs and 12 nodes.

    Here we present two simulations for a portion of network in the Salerno area, namely the segment Salerno-Fratte
    of the A3 highway. Simulations reported below show how different settings of "right of way" parameters affect
     the behaviour of traffic.

Below is reported a simulation of the entire network of Salerno.

Viale del Muro Torto

    Let us consider another portion of urban network of Rome, namely Viale del Muro Torto in the direction from
    Corso d'Italia towards Piazza del Popolo. We compute approximate solutions starting from an empty configuration
    and using as boundary data experimental data provided by the municipal society for traffic monitoring and control
    of Rome, namely ATAC S.p.A.
    Traffic is observed through sensors located along roads of some areas of the city, which acquire every minute traffic
    data such as flux,velocity and occupation rate. Approximate solutions are computed by Godunov's method with
    boundary conditions given by measured data.
