Abstract

Because of the increasing density of the traffic flow in urban areas there is a need for optimal performance of traffic lights. In this paper we study a model that describes the evolution of the queue lengths at an intersection of two two-way streets with controllable traffic lights on each corner (four phases in each cycle). We want to compute the traffic light switching scheme that minimizes a given criterion, such as average queue length over all queues, worst case queue length, average waiting time, a combination, etc. We solve the associated optimization model with linear complementarity constraints by a simulated annealing approach. We also present some numerical examples corresponding to the junction Finisterre avenue and Ronda de Nelle streets in A Coruña.
