Simulation of a vehicular traffic system based on queueing network models: comparative analysis of two models

In previous works [1], [2], [3], [4], [6], [7], [8], [9] we presented the study for modeling and simulation of vehicular traffic systems based on queuing networks. Specifically, in paper [1], we studied the urban network located in North Siena, in the city of Siena (Italy), in its actual composition, after the Municipality has done some changes for vehicular flows management. This system is based on two roundabout and a crossroad, as the following picture will show in Figure 1. In this work, we are going to conclude our previous study, comparing the actual vehicular flow and the one derived from an alternative system, foreseen by the PRG of the Municipality of Siena, that is composed of three roundabout and that has not been implemented yet.
