Resumo
Road Ecology is a scientific discipline that studies the effects of transport’s infrastructure such as roads, railways and canals on the ecosystem. Ecological effects including habitat destruction and fragmentation, increased erosion and pollution, and, particularly disturbing, the roadkill, which can be highly impacting populations of low-density species such as endangered species, having the potential to significantly affect biodiversity. Even with a considerable increase in recent studies on the subject, there are large gaps in knowledge about the effects of highways, and especially on how these effects affect animal populations, man, and ways to minimize or mitigate environmental impacts. These gaps are especially worrying in countries such as Brazil, which opted for a road modal and thus, presents an extensive network of highways.
Brazil even develops research and publishes on road ecology, being the third country that contributes most to the world scientific production, but there is a predominance of roadkill studies and a low number of studies on mitigation measures, and roadkill studies are lacking standardization in the methodology adopted by the researchers. In this study, the detection rate of animals of different taxonomic classes was analyzed using different tracking speeds, and it was observed that the speed of 5 km.h-1 is the one that best serves the purpose of pointing to the actual trampling rate.
Then within road ecology, several problems affect the human being, but traffic accidents are considered a neglected public health problem, especially in developing countries. There is a need to understand the factors contributing to the aggravation of traffic accidents, and as a contribution to this understanding, this study investigated automobile accidents with runway exit with or without collision in the vegetation of the domain strip. It was found that tree collision increases the probability of mortality (3.16 times) and severity of injury in accidents when vehicles left the roadway.
