Priorização passiva do transporte coletivo por ônibus em sistemas centralizados de controle de tráfego

Abstract

This work had as its main objective to assess the operational performance of passive bus priority techniques in fixed and real time signal systems at one of the main arterial corridors in Fortaleza. As a secondary objective, it also evaluated the operational benefits of SCOOT adaptive signal control, comparing it to well adjusted fixed time plans optimized by TRANSYT, for periods of medium and high traffic volumes. In evaluating scenarios, the following performance measures were considered: vehicle delay and number of stops simulated by SCOOT, as well as buses and autos travel times observed in the field during each scenario’s operation. The results did not favor the adoption of passive priority schemes in the selected corridor, leading to the conclusion that SCOOT real time control, programmed for a good signal progression of the general traffic (buses and autos), is the best signal control strategy for an arterial corridor with similar characteristics as the one under analysis.
