Goal:The study aims to consolidate papers published on the evaluation of investments in cargo transportation in Brazil with a focus on the sustainable perspective, taking into account not only economic but also social and environmental concepts. Design / Methodology / Approach: The method used is based on a keyword tree on scientific basis from november 2016 to february 2017 to identify models for evaluating new and existing infrastructure projects, highlighting the main variables adopted and the gaps of these models. Results: The aim of this study is to bring more transparency among different alternatives of road projects. Limitations of the investigation:The keyword tree methodology may not identify important studies in other languages or older. Practical implications: The study is helpful to policy-makers in their decisions to choose a road project for investment. Originality / Value: The originality of this study lies in the sustainable perspective for evaluating road transport.
Freight transportation in Brazil is heavily based on the road mode bringing heavy dependence of this mode to the country and some consequences such as high operating costs and high air emissions. For these reasons, it was considered the necessity of evaluating new investments made in this mode from a sustainable perspective, taking into account not only economic but also social and environmental concepts. Towards this purpose, the study develops an evaluation model of road transport infrastructure, the TIM, which will help decision making in situations of choice between different alternatives of road projects. The model includes ten variables that count from the initial investment in the road to air emissions of carbon dioxide. All are monetarized individually and then consolidated into a single equation. The result of applying the model is innovative when considering the three spheres of sustainability to evaluate future road transport projects and rank them.
Goal: This article aims to present a mathematical modelling study to quantify greenhouse gas emissions in the scope of urban mobility and propose actions for more sustainable cities. Methodology: This presents an application focused on trips made by cars and motorcycles in some neighborhoods of the City of Rio de Janeiro during 2016 in order to quantify from mathematical equations the greenhouse gas emissions and their proportion to the total greenhouse gases emission of transport in the city, while presenting the capacity of the current bicycle infrastructure to absorb the same displacements with zero carbon trips. Results: The study reached the result of 127 thousand tons of greenhouse gases emitted by cars and motorcycles, representing 1,64% of the total transport emissions and 2,73% of road transport in this city in 2016. Limitations of the investigation: The research is limited to the neighborhoods under analysis and the daily travel rate per inhabitant by type of transport. Practical implications: The study provides environmental impact assessment material able to support proposals for practical applications aimed at mitigating greenhouse gas emissions. Originality / Value: Measurement of environmental impacts and applications in the transport of the city of Rio de Janeiro, which can be used for comparisons with other neighborhoods in the city and/or other cities.

O avanço e aplicação de tecnologias inovadoras e disruptivas nos espaços industriais, está delineando a quarta revolução industrial, ou Indústria 4.0. Dessa forma, o presente artigo apresenta um modelo de maturidade, elaborado por meio do estudo de caso, utilizando o método Delphi adaptado, para avaliar o nível de maturidade de um Centro de Distribuição de Medicamentos na Baixada Fluminense, Estado do Rio de Janeiro - Brasil. O objetivo principal é descrever as tecnologias habilitadoras e mapear o nível de maturidade da logística desse centro de distribuição, sobre a realidade instalada e o potencial da empresa no atendimento dos requisitos da Indústria 4.0. Para isso, utilizou-se a metodologia de desenvolvimento do modelo de Maturidade - German Academy of Science and Engineering (ACATECH), que se baseia em seis etapas: informatização, conectividade, visibilidade, transparência, previsibilidade e adaptabilidade. Apresenta-se ao final do processo um modelo dividido em oito dimensões, agrupadas em três aspectos: Tecnologia, Organização e Pessoas. A aplicação prática do modelo revelou que o nível de maturidade desta empresa ainda não está dentro das práticas e conceitos da Industria 4.0; entretanto, a empresa está no processo de digitalização uma vez que a informação é substituída por componentes e sistemas conectados. Constata-se, então, que a empresa está no nível 2 e precisa homogeneizar todos os processos em sua cadeia de valor, introduzindo o tema “Industria 4.0” nas pautas de planejamento, investimento em tecnologias habilitadoras em toda linha de produção e capacitação continua dos seus colaboradores.
