Análise de padrões de ciclo de condução em segmentos viários: um estudo da operação dos veículos de carga - VUC em Fortaleza

Abstract

Driving cycles are used intensively in the estimation of vehicular emissions and in representations of local traffic. Given the increasing damage to the environment and health of the population caused by vehicular emissions, the study of this type of tool is essential, although it is still scarce. The present work seeks analyzes the driving cycles of road segments, through the identification of the factors that influence it and the associated vehicular emissions. For the construction of the driving cycles, real conduction data from 28 drivers were used, collected in 2019, who traveled on three major avenues of the city of Fortaleza using Urban Freight Transportation, with diesel cycle engine, that for construction of driving cycle purposes they were divided into smaller segments delimited by the presence of traffic light. During the trips, there was on-board monitoring of driving cycle parameters, location and pollutant emissions every 1 Hz. In general, the results showed the influence of the presence of traffic lights on the speeds developed in each segment and, consequently, on the emission of pollutants. The stretches that showed greater variations in the average developed speeds resulted in much higher emission levels than the stretches where the average speed was constant.
