Abstract(s)
Neste trabalho tem lugar uma análise da sinistralidade rodoviária baseada no modelo ergonómico de análise dos acidentes de trabalho, segundo o qual os fenómenos devem ser abordados num contexto global e sistémico, isto é, enquanto acontecimentos ocorridos no âmbito do sistema homem-máquina.
Nesta perspectiva consideraram-se como variáveis relevantes para a explicação do número de acidentes auto nas estradas portuguesas, o número de novos veículos em circulação, o consumo de gasolina, e o
número de novos encartados.
O modelo de regressão aplicado as observações disponíveis (1 980- 1990) permitiu extrair uma variável explicativa: os novos encartados. A inexperiência de condução emerge deste modo como o principal factor
a influenciar o número de acidentes. Em todo o caso, a reduzida dimensão da amostra e a não inclusão de outras variáveis pertinentes, recomendam cautela na análise destes resultados, que devem ser vistos como
exploratórios.
Discutem-se também as implicações que a abordagem ergonómica poderá vir a assumir nas futuras campanhas de prevenção e segurança rodoviárias.
In this paper, traffic accidents are analyzed based on an ergonomic perspective. This approach stands for the analysis of accidental events in a global and systemic context, considering the complexity of manmachine systems. In this perspective, the relevant variables considered, in what the explanation of accidents to occur is concerned, are the following: the number of new vehicles, gas consumption, and the number of people obtaining new driving licences. The regression model which has been applied to available observations (1980-1990) allows to extract a single variable: the mew) drivers. The inexperience of driving arouses as the main influent factor for the growing number of accidents (nevertheless, the limited sampie size and the omission of other pertinent variables, implies that this research should be considered as exploratory). The implications that this approach may bring into future research and practice are also discussed, namely in terms of accident analysis and prevention.
