Fatores associados aos acidentes de trânsito graves envolvendo condutores de automóvel e motocicleta: uma análise para as BR 101, 116 e 230 na Região Nordeste em 2007 e 2016. 2019. 196f. Dissertação (Mestrado em Demografia) - Centro de Ciências Exatas e da Terra, Universidade Federal do Rio Grande do Norte, Natal, 2019.https://repositorio.ufrn.br/jspui/handle/123456789/27489The main objective of the present study was to identify the factors associated with serious traffic accidents (occurrence of serious injury/death among automobile and motorcycle drivers) in the stretches of the BR 101, 116 and 230 highways located in the Northeast Region, in the years 2007 and 2016. Across the world, road traffic crashes, which are one of the external causes of morbidity and mortality, have been responsible for a considerable number not only of deaths but also of permanent physical and psychological sequels to many of those surviving those events. In this perspective, studies of this type become of fundamental importance in specific sections considered critical, in addition to turning to the differentials of risks between types and occupants of vehicles. In order to achieve the proposed objective, traffic accident records made available by the Federal Highway Police (FHP) were used, of which 2,692 were cases related to motorcycle and motorcycle drivers in 2007 and 3,011 cases in 2016. The data were initially submitted to descriptive analysis and, later, to the inferential method using Poisson regression with robust variance. The multiple regression models were constructed in blocks, the variables included in this order: Model 1 (demographic variables), Model 2 (road/environmental variables), Model 3 (vehicle variables) and Model 4 (presumable causes of accidents according to the epidemiological triad). All analyzes were segregated according to the year, highway and vehicle type. Among the main results, the following factors were identified as factors associated with the severely injured or deceased automobile driver's outcome in 2007: BR 101: type of single track (RR=1.93, p<0.10) and frontal collision (RR=1.81, p<0.05), BR 116: crossing (RR=2.88; p<0.10) and frontal collision (RR=1.92, p<0.05), BR 230: crossing (RR=3.11, p<0.05) and single track (RR=1.74, p<0.05). For 2016 were: BR 101: day phase at night (RR=1.52, p<0.05) and frontal collision (RR=1.92, p<0.05), BR 116: phase of the day at dawn (RR=1.83, p<0.05) and frontal collision (RR=2.55, p<0.05), BR 230: male gender (RR=3.71, p<0.05) and crossing (RR=3.45, p<0.05). They have already been highlighted as factors associated with the severely or deceased motorcycle driver's outcome in 2007: BR 101: day at dawn (RR=1.84, p<0.05) and frontal collision (RR=1.60, p<0.05), BR 116: friday to sunday (RR=1.37, p<0.10) and frontal collision (RR=1.35, p<0.10), BR 230: day to night phase (RR=1.78, p<0.05) and day at daybreak (RR=1.76, p<0.10). For 2016 were: BR 101: phase of the day at dawn (RR=1.47, p<0.10) and frontal collision (RR=1.68, p<0.05), BR 116: age group of 50 years and over (RR=1.32, p<0.10) and frontal collision (RR=2.10, p<0.05), BR 230: phase of the day at middle of the night (RR=1.41, p<0.05) and frontal collision (RR=1.76, p<0.05). In general, the study showed that the severity of road traffic crashes is not only related to the individual characteristics and behaviors of the drivers, but also to factors related to the pathways and environmental conditions of the moment of the accident, which evidences the need for actions prevention of these occurrences.Acesso AbertoAcidentes de trânsitoCausas externasPolícia Rodoviária FederalRodovias FederaisRegião NordestemasterThesisCNPQ::CIENCIAS SOCIAIS APLICADAS::DEMOGRAFIA
