    A lack of representative European accident data to aid the development of safety policy, regulation and technological advancement is a major obstacle in the European Union. Data are needed to assess the performance of road and vehicle safety and is also needed to support the development of further actions by stakeholders. A recent analysis conducted by the European Transport Safety Council identified that there was no single system in place that could meet all of the needs and that there were major gaps including indepth crash causation information. This paper describes the process of developing a data collection and analysis system designed to partly fill these gaps. A project team with members from 7 countries was set up to devise appropriate variable lists to collect fatal crash data under the following topic levels: accident, road environment, vehicle, and road user, using retrospective detailed police reports (n=1,300). The typical level of detail recorded was a minimum of 150 variables for each accident. The project will enable multidisciplinary information on the circumstances of fatal crashes to be interpreted to provide information on a range of causal factors and events surrounding the collisions. This has major applications in the areas of active safety systems, infrastructure and road safety, as well as for tailoring behavioural interventions

    The development of a multidisciplinary system to understand causal factors in road crashes

    The persistent lack of crash causation data to help inform and monitor road and vehicle safety policy is a major obstacle. Data are needed to assess the performance of road and vehicle safety stakeholders and is needed to support the development of further actions. A recent analysis conducted by the European Transport Safety Council identified that there was no single system in place that could meet all of the needs and that there were major gaps including in-depth crash causation information. This paper describes the process of developing a data collection and analysis system designed to fill these gaps. A project team with members from 7 countries was set up to devise appropriate variable lists to collect crash causation information under the following topic levels: accident, road environment, vehicle, and road user, using two quite different sets of resources: retrospective detailed police reports (n=1300) and prospective, independent, on-scene accident research investigations (n=1000). Data categorisation and human factors analysis methods based on Cognitive Reliability and Error Analysis Method (Hollnagel, 1998) were developed to enable the causal factors to be recorded, linked and understood. A harmonised, prospective “on-scene” method for recording the root causes and critical events of road crashes was developed. Where appropriate, this includes interviewing road users in collaboration with more routine accident investigation techniques. The typical level of detail recorded is a minimum of 150 variables for each accident. The project will enable multidisciplinary information on the circumstances of crashes to be interpreted to provide information on the causal factors. This has major applications in the areas of active safety systems, infrastructure and road safety, as well as for tailoring behavioural interventions. There is no direct model available internationally that uses such a systems based approach

    Stakeholder's contribution. Deliverable 1.3 of the EC FP7 Project DaCoTA

    Get PDF
    The aim of DaCoTA’s Work Package 1 is to shed light on road safety policy-making and management processes in Europe and to explore how these can be better supported by data and knowledge. This was done by assessing demands and views of stakeholders as well as by building a good practice model for road safety management investigation. Future versions of the European Road Safety Observatory (ERSO, www.erso.eu) are envisaged to be built on the findings of this project. This report describes the methodology and presents the first aggregated results of an on-line stakeholder consultation carried out in Task 1.3. The survey was successfully carried out among more than 3000 road safety stakeholders in Europe and beyond

    Preclinical stiff heart is a marker of cardiovascular morbimortality in apparently healthy population

    Background: The prognostic significance of impaired left ventricular (LV) relaxation and increased LV stiffness as precursor of heart failure with preserved ejection fraction and death is still largely unknown in apparently healthy subjects. Methods: We constituted a cohort of 353 patients with normal ejection fraction (>45%) and no significant heart disease, based on a total of 3,575 consecutive left-sided heart catheterizations performed. We measured peak negative first derivative of LV pressure (-dP/dt) and operating chamber stiffness (Κ) using a validated equation. Patients were categorized as having: 1) normal diastolic function, 2) isolated relaxation abnormalities (-dP/dt > 1860mm Hg/sec and K <0.025mm Hg/ml), or 3) predominant stiff heart (K ≥0.025mm Hg/ml). Results: During a follow-up of at least 5 years, the incidence of the primary composite endpoint (death, major arterial event, heart failure, and arrhythmia) was 23.2% (82 patients). Compared to isolated relaxation abnormalities, predominant stiff heart showed stronger prognostic significance for all events (p=0.002), namely heart failure (HR, 2.9; p=0.0499), cardiac death (HR, 5.8; p=0.03), and heart failure and cardiac death combined (HR, 3.7; p=0.003). Conclusion: In this apparently healthy population referred to our center for cardiac catheterization, the prevalence of diastolic dysfunction was very high. Moreover, predominant stiff heart was a better predictor of cardiovascular outcomes than isolated relaxation abnormalities

    Emotional experience and rate of decoding skills with kindergarten: Effect of multimodal integration of letters

    International audiencePurpose. Reading acquisition is among the more important and difficult learning that children must achieved. According to the self-teaching hypothesis, this acquisition relies on phonological recoding (grapho-phonological correspondences (GPC)), which allows the construction of an autonomous orthographic lexicon (Share, 1999). Moreover, this learning of GPC could be facilitated by motor experience of letter shape (e.g., Labat, Vallet, Magnan & Ecalle, 2015). It is also known that positive valence of words improves their future recognition and recall with elementary children (Monnier & Syssau, 2008). The present study focused on the impact of emotional words presentation on integration of its GPC.Method. We propose to compare the effect of sensorimotor trainings (visual vs. visuo-motor experience) and emotional material (positive vs. neutral) on word identification in 5-year-old children (N=40, on-going project). A procedure pre-test/ training (4 sessions, 1 session per day, 25 min per session, 2 GPC per session) /post-test is used. Tasks at the pre- and post-tests are the same: GPC judgment and pseudo-word decoding. Trainings differed on sensorimotor experience and emotional valence of words including the GPC in the initial position.Results. We expect the following pattern of improvement: motor experience and positive valence > motor experience and neutral valence > visual experience and positive valence > visual experience and neutral words (Activation-Integration model, Versace, Vallet, Riou, Lesourd, Labeye, & Brunel, 2014).Conclusions. Such findings would offer obvious practical implications in the educational and rehabilitation areas and would contribute to better understand the integrative factors on multimodal letter knowledge and reading acquisition of children
