1. Flexible pavement overlay design of UFJF ring road based on the new Brazilian mechanistic-empirical pavement design method
Abstract The procedures for design and reinforcement projects regarding flexible pavements available in Brazil are mostly based on empirical models developed from studies carried out in specific localities, and therefore, should only be used in cases where equivalent climatic and traffic conditions are observed. The national highway agencies in partnership w

2. Two innovative Brazilian programs relating to road safety prevention. A case study
ABSTRACT BACKGROUND: The World Health Organization (WHO) 2017 Global Conference in Montevideo, Uruguay, was dedicated to promoting successful cases and best practices in fighting and preventing noncommunicable disease (NCDs). The global effort undertaken by WHO aims to reduce road traffic deaths in order to meet goal number 3.4 of the sustainable developme

3. ERGONOMIC AND SAFETY CONDITIONS ASSESSMENT OF TRACTORS USED BY SMALLHOLDERS ACCORDING TO BRAZILIAN LEGISLATION AND CURRENT STANDARDS
ABSTRACT This article aimed to select items with which to evaluate the ergonomic and safety conditions in tractors used by smallholders and family farmers, based on standardization research and legislation for the sector. Brazil has a comprehensive set of technical standards and legislation for the agricultural machinery sector intended to guarantee product

4. Soil compaction on traffic lane due to soil tillage and sugarcane mechanical harvesting operations
ABSTRACT: Mechanical sugarcane harvesting increases soil compaction due to the intense traffic of agricultural machinery, reducing longevity of sugarcane crops. In order to mitigate the harmful effects caused by agricultural traffic on the soil structure in sugarcane fields, this study evaluated impacts of mechanical sugarcane harvesting on traffic lane unde

5. Fatores socioeconômicos aumentam os efeitos nocivos da poluição atmosférica e da temperatura na mortalidade
RESUMO: Objetivo: Verificar os efeitos do PM2,5 e da temperatura na mortalidade por doenças cardiovasculares segundo status socioeconômico e proximidade do tráfego. Método: Utilizaram-se séries temporais por meio da classe dos modelos aditivos generalizados com a opção de regressão de Poisson, a 5% de significância. Analisou-se interação entre

6. Avaliação da influência do entorno no uso das estações de bicicletas compartilhadas
Resumo O adensamento urbano causa inúmeros problemas de mobilidade, como os congestionamentos, os acidentes de trânsito e a dificuldade de deslocamento para a população. A busca de novas soluções para esses problemas de mobilidade urbana se tornou cada vez mais necessária para proporcionar melhor qualidade de vida à população. Nesse contexto, a Pr

7. Advances in Mexico in the middle of the Decade of Action for Road Safety 2011–2020
ABSTRACT OBJECTIVE To analyze the progress towards the accomplishment of the expected goal in the middle of the Decade of Action for Road Safety 2011–2020 in Mexico and its states. METHODS This is a secondary analysis of road traffic deaths in Mexico between 1999 and 2015. We projected the trend for the period 2011–2020 using a time series analysis (

8. COST-EFFECTIVE BANDWIDTH PROVISIONING IN MICROWAVE WIRELESS NETWORKS UNDER UNRELIABLE CHANNEL CONDITIONS
ABSTRACT Cost-effective planning and dimensioning of backhaul microwave networks under unreliable channel conditions remains a relatively underexplored area in the literature. In particular, bandwidth assignment requires special attention as the transport capacity of microwave links is prone to variations due to, e.g., weather conditions. In this paper, we f

9. DECISION WITH ARTIFICIAL NEURAL NETWORKS IN DISCRETE EVENT SIMULATION MODELS ON A TRAFFIC SYSTEM
ABSTRACT This work aims to demonstrate the use of a mechanism to be applied in the development of the discrete-event simulation models that perform decision operations through the implementation of an artificial neural network. Actions that involve complex operations performed by a human agent in a process, for example, are often modeled in simplified form w

10. Comparison between common traffic lights and three types of traffic lights with visual cycle – a safety and capacity analysis
Abstract The objective of this paper is compare the common traffic lights (CTL) to three different types of traffic lights with countdown displays (SCD) and assess their effects on road safety and capacity. This comparison is required because the results found in the literature are divergent among countries and cities, and one of the SCD analyzed in our stud

11. A DISTRIBUTION FOR THE SERVICE MODEL
ABSTRACT In this paper, we propose a distribution that describes a specific system. The system has a heavy traffic, a fast service and the service rate depends on state of the system. This distribution we call the Maximum-Conway-Maxwell-Poisson-exponential distribution, denoted by MAXCOMPE distribution. The MAXCOMPE distribution is obtained by compound distr

12. A Tool for Real-Time GNSS Performance Analysis in Air Traffic Management
ABSTRACT: This article introduces a numeric model, developed in a MATLAB environment, in order to monitor NAVSTAR GPS performances concerning accuracy effects and interference phenomenon. The model will be presented as a starting point for a future production of an open-source software, shareable and enlargeable, which will be able to provide real-time infor
