Decision making techniques have become increasingly widespread in the technical field. The use of such tools by Traffic Engineers assists in analyzing the performance of new urban settings, the definition of new coordination strategies, traffic signal isolation, among others, as to contribute to the effectiveness of the traffic control system. With increasing problems related to traffic in large cities, the implementation of traffic control signals emerges as one of the mitigating measures. As there are several national and international methods used in the implementation of traffic signals, depending on the characteristics of the cities in which they originate, it is necessary not only to identify the sites where traffic signals should be installed, but also to utilize different methods. Such methods include traffic signal optimization and simulation tools, which assist in the analysis of operational impacts through performance measures, indentifying which are the real improvements resulting from the implementations, considering other realities. The present work will study a road section from the central area of the city of Fortaleza, in the state of Ceará, Brazil. The following stages were defined: application of the studied methodologies of traffic control signal implementation, mode of operation, and operational coordination and evaluation. The traffic simulator Integration was used, and through its performance measurements it was possible to define the setting that exhibited the highest operational gains in relation to the current setting.
