A solução construtiva objetivou simular uma colisão automobilística e utiliza manequins representativos de crianças para fins de efeito demonstrativo e de convencimento sobre a necessidade de se reter crianças em veículos automotores. Trata-se de um trenó, guiado, que se desloca sobre trilhos sendo tracionado por cabo de aço e, capaz de, sem dano permanente, colidir contra uma barreira de impacto deformável. O equipamento foi concebido para fácil instalação em locais públicos e utiliza motor de indução para tracionar o cabo de aço e sistemas de automatização de aferição da velocidade, de aceleração e parada do motor. A instrumentação eletrônica utilizada na montagem do simulador permite avaliação do desempenho do equipamento para velocidades de até 20 Km/h / Abstract: Design, construction and evaluation of impact tests simulator performance of child restraint systems. The constructive solution aimed to simulate an automobile collision and uses dummies representing children for the purposes of demonstration effect and conviction about the need to retain children in motor vehicles. This is a sled, guided, moving on rails being pulled by steel cable and capable of, without permanent damage, crash into a deformable barrier impact. The equipment is designed for easy installation in public places and induction motor uses to pull the cable and speed measurement automation systems, acceleration and engine stop. The electronic instrumentation used in the simulator assembly allows assessment of equipment performance for speeds up to 20 km / h / Mestrado / Materiais e Processos de Fabricação / Mestre em Engenharia Mecânica

Child pedestrian injury and mortality is an issue of significant public health concern in the city of Johannesburg, Gauteng, in South Africa. Since there is a paucity of studies in the last decade or more on fatal childhood traffic and non-traffic injuries in Johannesburg, this study aspires to address the disproportion in this domain of research, and provide more recent, and comprehensive empirical evidence over a ten-year period. The overarching aim of this study was to describe and examine the magnitude, circumstances, and neighbourhood characteristics of fatal pedestrian injuries among children (0-14 years) in Johannesburg for the period from 2001 to 2010. More specifically, the objectives of the study were: firstly, to provide a comprehensive epidemiological description of the magnitude, trends and occurrence of pedestrian mortality among children; secondly, to describe and examine the epidemiology of child pedestrian mortality in relation to children as motor vehicle passengers; thirdly, to describe and examine child pedestrian mortality in relation to non-traffic injuries, in particular, burns and drowning; and fourthly, to assess the influence of neighbourhood characteristics on child pedestrian mortality. The study conceptualised pedestrian road safety within an ecological systems framework. The study used quantitative descriptive, and multivariate logistic regression methods of analysis to examine child pedestrian mortality data. The study drew on data from the National Injury Mortality Surveillance System (NIMSS) and the Census 2001. The main findings indicated that black, male children aged 5 to 9 years (11.02/100 000) are the most vulnerable, and that mortality occurred predominantly during the afternoons and early evenings (12h00-16h00 and 16h00-21h00), over weekends, during school holidays, and to a lesser extent, during non-holiday months. In addition, neighbourhood characteristics that reflected concentrations of disadvantage, single female-headed households and residentially stable areas were associated with child pedestrian mortality. The study findings highlight the need for critical action in terms of investment in child pedestrian safety research, and appropriate prevention initiatives guided by stringent evidenced-based studies, and the design of safe pedestrian, vehicular and urban environments. / Psychology / D.

Submitted in fulfilment of the academic requirements for the degree of Magister Technologiae: Department of Civil Engineering and Surveying, Faculty of Engineering and the Built Environment, Durban University of Technology, 2009. / The annual incidence of pedestrian casualties on South African roads is approximately 34 000. This includes 4 000 deaths, 10 000 serious injuries and 20 000 minor injuries, costing the country an estimated R2,55 billion. A large number of injuries involve children and this is distressing but preventing this is a challenge. Statistics indicate that pedestrians are most at risk. School children have been identified as forming a considerable percentage of pedestrians. Consequently it is important to understand factors that influence children's travel patterns as an initial step toward reducing the accident rate. This study examines children's travel patterns at primary and secondary schools in the eThekwini area. In the absence of statistics regarding journeys to transport children to school, a questionnaire survey was designed to determine demographics, mode of travel to school, travel cost and duration, factors influencing choices of alternate modes of travel and problems experienced during school travel in terms of road safety. In addition, an on-site investigation was undertaken to assess the relevant engineering aspects including geometric design, traffic calming, signage and other traffic management aspects. This study focuses on scholar transport and discusses the findings of pilot and focal surveys. On analyzing the data, various problems were identified, namely: the road environment favours drivers over pedestrians, an absence of a formal travel plan, poor driver behaviour and an absence of dedicated school buses. A range of possible solutions is recommended. The recommendations focus on the Engineering, Enforcement and Evaluation aspects.
