“…in average crash speeds, personality traits or emotions), but a different reporting rate of single-vehicle crashes in comparison with multiple-vehicle crashes might provide an important alternative explanation. The existing literature showed consistently lower reporting rates for single vehicle crashes than for multiple vehicle crashes (Alsop & Langley, 2001;Amoros et al, 2006;Elvik & Mysen, 1999). Unfortunately, the magnitude of the underreporting is unclear and varies according to the involved road user type.…”

The severity of 1491 crashes on 148 roundabouts in Flanders-Belgium was examined in order to investigate which factors might explain the severity of crashes or injuries and to relate these factors to the existing knowledge about contributing factors for injury severity in traffic.Logistic regression and hierarchical binomial logistic regression techniques were used.A clear externality of risk appeared to be present in the sense that vulnerable road user groups (pedestrians, bicyclists, moped riders and motorcyclists) are more severely affected than others. Fatalities or serious injuries in multiple-vehicle crashes for drivers of four-wheel vehicles are much rarer.Injury severity increases with higher age. Crashes at night and crashes outside built-up areas are more severe. Single-vehicle crashes seem to have more severe outcomes than multiplevehicle crashes. However, systematic differences in the reporting rate of crashes are likely to exist and may have affected the stated results. Correlations with important, but unobserved variables like the impact speeds in the crashes might exist as well and could provide an alternative explanation for some results.3

“…Unfortunately, the quality and completeness of the DGT traffic crash database have yet to be assessed. We must therefore assume that these data are affected by the same problems as have been described previously for similar databases in other countries, i.e., under-representation of less severe accidents (9,23,24) and an undetermined degree of inaccuracy for driver-related variables (25)(26)(27). Inaccuracies in the ascription of infractions to each driver have been noted previously.…”

PURPOSE:To assess the strength of association of main driver-dependent risk factors with the risk of causing a collision between vehicles in Spain, from 1990 to 1999. METHODS:The data for this paired-by-collision, case-control study were obtained from the Spanish Dirección General de Tráfico traffic crash database. The study included all 220,284 collisions involving two or more vehicles with four or more wheels, in which only one of the drivers involved committed an infraction. Infractor drivers comprised the case group; noninfractor drivers involved in the same collision were their corresponding paired controls. RESULTS: All driver-dependent factors were associated with the risk of causing a collision. The highest adjusted odds ratio estimates were obtained for sleepiness (64.35; CI, inappropriate speed (28.33; CI,, and driving under the influence of alcohol with a positive breath test (22.32; CI,). An increase in the number of years in possession of a driving license showed a protective effect, albeit the strength of the effect decreased as age increased. CONCLUSIONS: Our results emphasize the urgent need to implement strategies aimed mainly at controlling speeding, sleepiness, and alcohol consumption before driving-the main driver-dependent risk factors for causing a vehicle collision.

“…Difficulties with police injury assessments are also amply documented and the biases and understatement well evidenced (Jeffrey et al, 2009; Department for Transport UK, 2006;Alsop & Langley, 2001;Lopez et al, 2000). A particular issue is the definition of serious injury which varies widely (International Transport Forum, 2012).…”

Record linkage for road traffic injuries in Ireland using police hospital and injury claims data

The study of non-fatal road traffic injuries is growing in importance. Since there are rarely comprehensive injury datasets, it is necessary to combine different sources to obtain better estimates on the extent and nature of the problem. Record linkage is one such technique. In this study, anonymised datasets from three separate sources of injury data in Ireland -hospitals, police and injury claims are linked using probabilistic and deterministic linkage techniques. A method is proposed that creates a 'best' set of linked records for analysis, useful when clerical review of undecided cases is not feasible. The linkage of police and hospital datasets shows results that are not dissimilar to those found in other countries, with significant police understatement especially of cyclist and motorcyclist injuries. The addition of the third dataset identifies a large number of additional injuries and demonstrates the error of using only the two main sources for injury data. The study also underlines the risk in relying on the LincolnPetersen capture-recapture estimator to provide an estimate of the total population concerned. The data show that road traffic injuries are significantly more numerous than either police or hospital sources indicate. It is also argued that no single measure can fully capture the range of impacts that a serious injury entails.
