This paper proposes a model to implement and simulate different traffic-flow conditions using quantum graphs, successfully modeling various types of traffic flow and comparing the results with classical models.
We propose a model to implement and simulate different traffic-flow conditions in terms of quantum graphs hosting an ( N +1)-level dot at each site, which allows us to keep track of the type and of the destination of each vehicle. By implementing proper Lindbladian local dissipators, we derive the master equations that describe the traffic flow in our system. To show the versatility and the reliability of our technique, we employ it to model different types of traffic flow (the symmetric three-way roundabout and the threeroad intersection). Eventually, we successfully compare our predictions with results from classical models. (C) Copyright A. Nava et al.
