Progressão em tempo real versus tempo fixo por banda de passagem em períodos de baixa demanda–estudo de caso

Abstract

The purpose of this paper is to evaluate the effectiveness of implementing maximum-band fixed-time signal progression along Fortaleza’s arterial corridors, during low traffic demand periods. The analysis, based on a case study, consisted of comparing the fixed-time strategy to the signal progression obtained with the adaptive control system SCOOT, used at Fortaleza’s Urban Traffic Control System – CTAFOR, taking as performance measures values of vehicle delay and progression quality, simulated by SCOOT. The results of the inferential statistical analyses confirmed the initial expectations that, during low demand periods, the maximum-band fixed-time signal progression reduces vehicle delay and stops at the corridor’s links, also bringing benefits to the approaches of the crossing streets.
