Análise de compatibilidade geométrica do padrão de veículos de carga regulamentados em cidades brasileiras: o caso de Fortaleza

Abstract

Road freight transports has a high impact on the urban road use, contributing to increase in congestion rates and aggravate mobility conditions in general. To minimize these impacts, several Brazilian cities have been implementing regulatory policies for freight vehicles. In this context, this work aims to analyze restrictive measures for the movement of freight vehicles in the ten biggest cities in Brazil, ranked by population: São Paulo, Brasilia, Salvador, Fortaleza, Belo Horizonte, Manaus, Curitiba, Recife and Porto Alegre. First, the traffic regulation of freight vehicles in these cities were analised. Then, using Autoturn software, curves were simulated for 83 freight vehicles, including the most commercialized in 2017, in order to know their offtracking. This information, combined with other technical characteristics of these vehicles, allowed a comparative analysis among policies adopted by Brazilian cities, determining their impacts and the effectiveness of each one. Considering the relation between offtracking and maximum payload (stocking), the Urban Freight Vehicle (VUC) adopted in São Paulo since 2016 was presented as the most efficient measure among the restrictions analyzed, since it provides a vehicle of load with high transport capacity, and low impact on road occupation. Finally, a case study was carried out in a dense region of Fortaleza, where was observed the geometric compatibility of a representative vehicle of the restrictive measures of each city in reference. The results of this study indicated which representative vehicles were compatible with the geometry of the analyzed tracks and the respective impacts produced.
