Atualização de planos de tempo fixo com base em dados históricos de sistemas centralizados de controle de tráfego

Abstract

In any kind of traffic signal control strategy there is the need to update the signal plans’ parameters to better serve the present traffic demand. The centralized traffic control systems, in special, allow a constant monitoring of travel pattern, making it easier to adjust signal plans to follow traffic flow variability. Due to such advantages, some Brazilian cities, such as Fortaleza, have adopted this signal control strategy in their more dense areas. In this context, this work was focused in the description of a methodology to update fixed-time signal plans developed by CTAFOR (Fortaleza’s Urban Traffic Control System) staff, as well as in validating the methodology through a case study, assessing the operational performance of the produced signal plans.
