SWOV researched the similarities and differences between data on the official number of road deaths (determined by Statistics Netherlands (CBS)) on the one hand, and data of crash registration BRON (based on the police registration and processed by Rijkswaterstaat) on the other. This research is of interest to traffic safety professionals because m...

Linking Police accident records and Hospital discharge records. After selection of MAIS2+ (icd-derived AIS2005) we continue with the intersection, HDR-remainder and an estimate of absent cases (capture-recapture-like). A total number of serious injuries is estmated. Result: 20.000 MAIS2+ (of which one third is MAIS3+). The ratio MAS3+ to fatalities...

This study has analyzed sex-specific differences in pedestrian and cyclist accidents involving passenger cars. The most frequently injured body regions, types of injuries, which show sex-specific differences and the general accident parameters of females and males were compared. Accident data from three different European countries (Austria, Nether...

De drie noordelijke provincies – Groningen, Fryslân en Drenthe – hebben SWOV gevraagd om als basis voor een risicoanalyse een vergelijkende verkeersveiligheidsanalyse uit te voeren volgens de lagen van de zogeheten verkeersveiligheidspiramide. Een belangrijk hulpmiddel bij een risicoanalyse zijn zogeheten risico-indicatoren, ook wel prestatie-indi...

Objective: To reduce the number of severe injuries sustained by cyclists in crashes with vehicles, it is important to understand which kinds of injuries are occurring to identify what should be assessed by means of virtual testing. Method: A detailed analysis of injuries was made based on Swedish and Dutch accident data. The most frequently injured...

The EU research project SafetyCube pays specific attention to serious road injuries, defined as nonfatal road traffic casualties with an injury severity level of MAIS3+. By means of surveys, information was collected on current practices concerning the estimation of the number of MAIS3+ casualties and on costs related to serious road injuries in di...

To determine accurately the number of serious injuries at EU level and to compare serious injury rates between different countries it is essential to use a common definition. In January 2013, the High Level Group on Road Safety established the definition of serious injuries as patients with an injury level of MAIS3+(Maximum Abbreviated Injury Scale...

Background: Information about the burden of (non-fatal) road traffic injury is very useful to further improve road safety policy. Previous studies calculated the burden of injury in individual countries. This paper estimates and compares the burden of non-fatal serious road traffic injuries in six EU countries/regions: Austria, Belgium, England, T...

This report serves as background report and research account for the Road Safety Monitor 2017 (R-2017-17) and discusses: - developments in number of road fatalities and serious road injuries - developments in demographics, mobility and risk - developments in road safety indicators, and - road safety measures that have been taken

Background: To explore the impact of road injuries for different age groups, this study compares the health burden of road injuries in young adolescents-12 to 17 years of age-to those for older age groups. Young adolescents are underrepresented in road fatalities. However, their inexperience, developmental stage and use of bicycles may expose them...

Background Reliable data on the number of serious road injuries is a prerequisite for monitoring and evaluation purposes. In January 2013, the High Level Group on Road Safety representing all EU Member States established the definition of serious injuries as in-patients with an injury level of MAIS3+ (Maximum Abbreviated Injury Scale). Since then i...

Background: The consequences of injuries in terms of disabilities and health burden are relevant for policy making. This paper provides an overview of the current knowledge on this topic and discusses the health burden of serious road injuries in the Netherlands. Methods: The overview of current knowledge on disabilities following a road crash i...

This paper discusses the characteristics and injury patterns of serious road injuries (MAIS2+ inpatients) in the Netherlands. In the Netherlands, the actual number of serious injuries is estimated by linking police data to hospital data. The distribution of serious road injuries over 1) travel mode and gender and 2) crash type and age are compared...

This study set out to evaluate the effectiveness of low speed autonomous emergency braking (AEB) technology in current model passenger vehicles, based on real-world crash experience. The validating vehicle safety through meta-analysis (VVSMA) group comprising a collaboration of government, industry consumer organisations and researchers, pooled dat...

Based on existing literature, a system thinking approach was used to set up a conceptual model on the interrelationships among the components influencing adolescent road mortality, distinguishing between components at the individual level and at the system level. At the individual level the role of risk behaviour (sometimes deliberate and sometimes...

Monitor Policy Stimulus Road Safety 2013 – Research justification This report is a background document to the monitor of the Policy Stimulus Road Safety (Weijermars & Bos, 2014). The Policy Stimulus Road Safety was drawn up in 2012 and presents 23 extra measures that the Ministry of Infrastructure and the Environment and its administrative and soci...

The European Road Safety Observatory was established European Commission and first announced in the 2001 Transport White Paper1. It was further developed in the 2003 Road Safety Action Plan 2 where the Commission announced it was to establish a new European Road Safety Observatory (ERSO) to "co-ordinate all Community activities in the fields of roa...

Background Whereas the safety of teens in early licensing countries has been extensively studied, little is known about the safety of pre-license teens in late licensing countries, where these teens also may be at risk. This risk exists because of the combination of a) increasing use of travel modes with a high injury risk, such as bicycles and mop...

Within this research, the police under-reporting of non-fatal road accident casualties in eight European countries was examined by means of a common methodology applied in each country. Eight national studies were carried out using the common methodology, and this allowed to prepare valid estimates of the level of under-reporting of non-fatal road...

Not all road traffic casualties are reported by the police. Using the correct data in addressing road safety issues and evaluation of road safety measures is relevant for designing effective road safety policies, to set the right priorities and act on them. Therefore it is necessary to estimate the higher 'real number' of casualties annually. This...

This is a report. An important objective within SafetyNet WP1 is to improve the compatibility of road accident data throughout Europe. Currently, the CARE database contains a large number of road accident variables in disaggregate form, but it is acknowledged that more variables and values are necessary to better describe and analyse the road accid...

We have studied two new tetragonal compounds, CeCuAl 3 and CeCuGa 3 , which both display very large specific‐heat, c(T), values at low temperature. CeCuAl 3 orders antiferromagnetically below T N =3.0 K, while CeCuGa 3 remains paramagnetic down to 0.4 K. The large values of c(T) in these and other cerium intermetallics are interpreted as resulting...

We have studied the magnetic anisotropy on a single crystal of the new heavy-fermion compound CePd2Al3. The magnetic moments lie in the hexagonal (a, b)-plane, but do not order antiferromagnetically, in contrast to annealed polycrystalline samples. The Kondo effect can account for the large specific heat at low temperatures. The small crystal-field...

We present an experimental study of the structural and magnetic properties of various polycrystalline samples of the new heavy-fermion antiferromagnet CePd2Al3, TN = 2.7 K. The relevant energy scales of the Kondo effect and crystal-field splitting are determined by comparing them with nonmagnetic LaPd2Al3. The critical dependence of the magnetic pr...
