Control Optimo del Trafico Mediante Semaforos con Observadores

Abstract

In order to improve the travel time of surface public transport vehicles (PT) (bus, tramway, etc.), several cities use urban traffic control (UTC) systems enabling to give priority to PT. This article reviews these systems. Further to a debate on their insufficiencies for a global regulation on the urban traffic on a whole network, the paper proposes intermodal regulation strategies, operating on intersection traffic lights to regulate traffic, favoring the PT. These strategies are based on the linear quadratic (LQ) optimal control theory. The article proposes different ways to take the PT into account in the optimisation problem. The simulation tests are carried out on a network of eight intersections and two PT lines.
