In order to improve the traffic performance of a road network composed of roadways with traffic lights, a signal-coordinating system is established, consisting of a set of measures and decisions related to the prioritization of certain roads and to the allocation of green time for each intersection or set of intersections in order to increase user comfort, reducing traffic congestion and minimizing delays, as long as the coordination system is well suited to the traffic conditions of the region. To evaluate the quality of the progression in an arterial route operating according to a signal-coordinating system, computer simulation models are used. In this context, the main objective of this study was evaluating and proposing adjustments to the signal coordination of a section of an important arterial route of Fortaleza, Pontes Vieira Aevnue, using the software PTV VISTRO. The methodology utilized involved the identification and selection of performance measures, the coding of the network in the software from data obtained in the field and the comparison of three scenarios – the observed in the field, the expected and the result of an optimization obtained through genetic algorithm – to evaluate the current situation and propose possible adjustments. From this analysis, it was identified that if the schedules defined by CTAFOR were guaranteed, a significant reduction in control delays would be observed due in the section under study. However, an optimization was suggested in the signal times of the route based on the result of the simulation performed.
