1. Service levels of highway toll plazas: the influence of factors on manual customer service
Abstract Paper aims To analyze service levels offered in a highway toll plaza and to test the influence of operational and human factors on manual customer service. Originality The methodology is an approach which involves systematic and efficient examination of multiple factors. This approach has been widely used in multiple areas; however, little researc

2. Analysis of a car door subjected to side pole impact
Abstract The results of a study on the response of a side impact beam located in a car door to impact loading is presented. The side impact beam is situated in both the front and rear side doors of a vehicle between the inner and outer shells to minimise intrusion into the passenger compartment during a collision whilst absorbing as much impact energy as pos

4. Effect of temperature gradients on the behaviour of jointed plain concrete pavements
Resumo Em muitos países da América Latina os pavimentos de concreto com juntas (JPCP) são calculados usando os métodos da “American Association of State Highway and Transportation Officials (AASHTO) ou da “Portland Cement Association” (PCA), os quais não levam em consideração explicitamente as condições climáticas específicas de cada região

5. Modelo de previsión de la progresión del área de fisuras en pavimentos asfálticos
This work presents the development of a model to predict cracking progression in hot-mix asphalt pavements, based on information obtained from a database maintained by State of Bahia Department of Transportation, with data collected in 2004. A factorial design was performed to arrange the data available in order to facilitate the statistical analysis. The fa

6. Transverse load distribution of skew cast-in-place concrete multicell box - girder bridges subjected to traffic condition
Concrete multicell box-girder bridges are a common choice among the designers for various ranges of bridges. In order to provide safer and greater speed of traffic, the roadway is built as straight as possible. The use of skewed bridges has increased considerably in the recent years for roadway. The skewed bridges have quite different mechanical behavior fro

7. Contribuição para calibração de curva de evolução de afundamentos em trilha de roda de revestimentos asfálticos com utilização de resultados obtidos de simulador de tráfego em escala real. / A contribution to the calibration of performance curves for the prediction of permanent deformation in asphalt pavements using the results obtained from a large scale mobile traffic simulator
Permanent deformation, or rutting, is a critical type of pavement distress given that it is directly associated with transportation costs, due to a reduction of the ride quality, and user safety, due to poor driving conditions or water build-up during rainy periods that affect the tire-pavement interaction. In the case of pavements of highways belonging to c

8. Aplicação do modelo de previsão de acidentes do HSM em rodovias de pista simples do Estado de São Paulo / Application of the HSM crash prediction method for two lane highways of the state of Sao Paulo
Nesta dissertação é feita uma avaliação dos resultados da aplicação do modelo de previsão de acidentes apresentado no Highway Safety Manual - HSM, publicado pela American Association of State Highway and Transportation Officials (AASHTO) no ano de 2010, para o caso de trechos de rodovia de pista simples localizados no interior do estado de São Paulo

9. Estimativa da emissão de poluentes pelo setor de transporte e análise das ocorrências de doenças respiratórias na área de proteção ambiental do Sistema Cantareira / Estimation of pollutant emissions by sector and transport analysis of respiratory diseases in the area of environmental protection System Cantareira
The global energy matrix is mainly composed by fossil fuels which when burned release air pollutants that affect the environment and human health. In this sense, monitoring health problems related to air pollution is important because it reinforces the need for change in national and international energy policies. This thesis presents a discussion on air pol

10. VANTS para sensoriamento remoto: aplicabilidade na avaliação e monitoramento de impactos ambientais causados por acidentes com cargas perigosas. / UAV for remoto sensing: applicability in assessment and monitoring of environmental impacts caused by accidents involving hazardous cargo.
A maior parte de desastres químicos no estado de São Paulo é gerada por acidentes com transporte rodoviário de cargas perigosas (cerca de 40%). A coleta de informações ambientais das áreas atingidas depende de vistoria emergencial que muitas vezes traz riscos e dificuldades às equipes de atendimento envolvidas. O objetivo principal da pesquisa foi ve

11. Impactos da formação espacial de preços na competitividade relativa da fruticultura irrigada do Estado do Ceará / Impacts of spatial price formation on relative competitivity of irrigated fruit culture in the State of Ceara
The irrigated areas in the state of Ceara have distinct productive and infrastructure structures. Fruit growing activities in these areas are subjected to market imperfections, since farmers are dependent on oligopolies when acquiring modern inputs and on oligopsonies when selling the fruit produced. Such economic distortions are a consequence of the spatial

12. Comportamento dos motoristas em interseções semaforizadas / Driver behavior at signalized intersections
The objective of this research was to characterize driver behavior at signalized intersections according to three aspects: (1) reaction at the onset of the amber phase; (2) behavior during the deceleration to stop at the signal; and (3) behavior during the acceleration to leave the intersection at the onset of the green. The data were collected at a signaliz
