Signalized traffic intersections control with uncertainties over lossy networks

In this paper, different traffic light control structures over communication links, including the decentralized, quasi-decentralized and distributed control, are considered for coordinating multiple intersections, which could be a great application of networked control signalized traffic light problem. It will help the designer to achieve certain objectives such as minimize the waiting time during the red light period and perform a better control in the next green cycle and more will be highlighted in this paper. A state space model of traffic dynamics under these different control structures is proposed considering most of the major effects of lossy communication links and the traffic uncertainties. Also, a sufficient condition for system stability is provided based on Linear Matrix Inequality (LMI). Finally, comparison of different types of networked control systems was done using simulation.
