1. Capacited Vehicle Routing Problem with CO2 Emission Minimization Considering Path Slopes
ABSTRACT This work presents the application of a CO2 emission estimation function for cargo vehicles on a Capacited Vehicle Routing Problems (CVRP) setting, considering route’s slopes variation. Comparisons were established with functions minimizing fuel consumption and route length in a case study about selective collection of recyclable waste at Sorocaba

2. Fatores de emissão de compostos carbonílicos medidos em um túnel do Rio de Janeiro, Brasil, em condições reais de dirigibilidade
Real-world vehicle emissions of carbonyls compounds (CC) were determined at the Rebouças Tunnel, Rio de Janeiro (Brazil). The tunnel is a two-bore tunnel with three lanes in each direction and has a length of 2840 m, divided in two sections. On average, approximately 5,000 vehicles (95% light duty) were passing the tunnel per hour. Sixteen samples were simu

3. Balanço de carbono em cidades da Amazônia: estudo de caso em Belém, Brasil
Resumo O município de Belém, no Pará, tem apresentado crescimento contínuo de sua área urbanizada e da frota de veículos nas últimas décadas. Essas mudanças estão também associadas a reduções na área de cobertura vegetal e ao aumento das emissões de CO2 locais. Há, portanto, a necessidade de se entender, de maneira integrada, a dinâmica das

4. Life cycle analysis of HCNG light-duty vehicle demonstration project
ABSTRACT The demonstration is an effective initiative to bridge the gap between a premature technology and its large-scale commercialization. A systematic method of LCA was used to perform the well-to-wheel analysis of a CNG light-duty truck operated with 0%, 15%, and 30% blends of hydrogen with compressed natural gas fuel under the system boundary of “per

5. Estimated evolution of total pollutant gas emissions associated with vehicle activity in the Metropolitan Region of Porto Alegre until 2030
ABSTRACT In recent years, the majority of economic sectors in Brazil have gone through processes of development and transformation. These processes have led to increases in environmental pollution of all kinds; air pollution being one of the most adverse. The Brazilian transportation sector, which heavily affects the air quality, experienced a significant in

6. Parametric Modal Study and Optimization of the Floor Pan of a B-Segment Automotive Using a Hybrid Method of Taguchi and a Newly Developed MCDM Model
Abstract The floor pan is an important component that connects the front and rear segments of the automotive underbody structure. Global stiffness and NVH characteristics of BIW are highly dependent to shape, thickness and mass of the body panels and could be evaluated by modal characteristics of these panels. The feeling of solidness and comfort of passenge

8. A review of low-level air pollution and adverse effects on human health: implications for epidemiological studies and public policy
The aim of this study was to review original scientific articles describing the relationship between atmospheric pollution and damage to human health. We also aimed to determine which of these studies mentioned public policy issues. Original articles relating to atmospheric pollution and human health published between 1995 and 2009 were retrieved from the Pu
