N2 - Traffic intersections are often the botlenecks of traffic systems. Given a traffic network, an optimal traffic signal control strategy can result in smooth traffic flow and thus reduce energy consumption and environmental impact at intersections. This study aims to develop a new multi-input and multi-output (MIMO) traffic signal control method that can improve network-wide traffic operations in terms of delay and energy consumption. In this context, a 35-intersection network of Bellevue, WA is used as the basis for the development of the algorithm, where modeling and intersection controls in a globalized seting are established using MIMO linear control theory and high matrix formulation. The proposed control method is evaluated in a microscopic traffic simulation environment, VISSIM. Simulation results show that the proposed method has much shorter average travel delays in the network when compared with the delays of conventional pretimed and actuated controls.
