Proposição de um método para escolha de interseções semaforizadas candidatas a atualização da tecnologia de controle

Abstract

The intensive fleet’s increase and the trips generated after the implementation of Trips Generators Poles have made worse the mobility in the urban areas of Brazilian cities. One of the most important items studied by Traffic Engineering are the observed conflicts in intersections, in which some control features can be seen: STOP sign, smallroundabouts and traffic lights. The latest are recommended to be installed by several traffic manuals, based in traffic flows, delay levels and accidents observed in the intersection, though those manuals don’t indicate which traffic light control technology shall be used. This Master Dissertation presents a methodology to hierarchize, in a traffic light network, which intersection must receive an update technology in its traffic control dispositive. The City of Fortaleza’s fixed-time traffic light network is analyzed to produce a rank indicating the intersections that need an up-to-date real-time centralized traffic control instead of fixed-time technology. This work was developed using Multi-Criteria Decision Analyzes (MCDA), allowing the knowledge of the relevant aspects in the decision context, according to the value judgments from the Fortaleza’s Traffic Lights Department (CTAFOR) staff.
