Despite the steadily declining number of pedestrian fatalities and injuries in most European countries during recent decades, pedestrian protection is still of great importance in the European Union as well as in Germany. This is because they still constitute a large proportion of road user casualties and are more likely to suffer serious and fatal injuries than most other road users. In 1999 only car occupants suffered more fatal injuries than pedestrians in Germany. In December 1998, EEVC WG 17 completed their review and updating of the EEVC WG 10 pedestrian test procedure that made it possible to evaluate the protection afforded to pedestrians by the front of passenger cars in an accident. Within the scope of this procedure, four different impactors are used representing those parts of the body which are injured very often and/or very seriously in vehicle-pedestrian-collisions. In a project executed by IKA and BASt, a small family car was tested according to the EEVC WG 17 test procedure. Afterwards modifications to the car were carried out in order to improve the pedestrian protection provided by the vehicle design. There were certain restrictions placed on the level of modifications undertaken, e.g. only minor modifications to vehicle styling and to the vehicle structures, which provide passenger protection. The redesigned vehicle was tested again using the WG 17 test procedure. The test results of the modified vehicle were compared with those of the standard vehicle and evaluated. The results show that considered measures for pedestrian protection in many areas of the vehicle front structure and the use of innovative techniques can lead to a significant reduction of the loads of pedestrians at an acceptable expense.

Umstellung der bautechnischen Bestimmungen im Brücken- und Ingenieurbau auf europäische Regelungen
(2002)
Der im November 1996 gefasste Beschluss des Bau-Koordinierungs-Normenaussschusses (NA) 07.1 "Brücken" nach einer baldmöglichen Anwendung der Eurocodes im Brückenbau wird nach Durchführung umfangreicher Vorarbeiten voraussichtlich Mitte 2002 mit der verbindlichen Einführung von DIN-Fachberichten verwirklicht werden. Seit Mitte 2001 stehen DIN-Fachberichte für die Bemessung und Konstruktion von Brücken- und Ingenieurbauwerken zur Verfügung, die in einer Erprobungsphase von etwa einem Jahr auf ihre Anwendbarkeit geprüft werden. Dies geschieht insbesondere anhand verschiedener Pilotprojekte. Die daraus gewonnenen Erfahrungen fließen in eine Fortschreibung der DIN-Fachberichte ein und sollen auch für die weitere Bearbeitung der Eurocodes bei CEN zur Verfügung gestellt werden. Gleichzeitig werden die zugehörigen vertraglichen Regelungen in den Zusätzlichen Technischen Vorschriften (ZTV) überarbeitet und zu einer ZTV-ING zusammengefasst. Die DIN-Fachberichte basieren auf den einschlägigen Eurocodes in der ENV-Fassung und den zugehörigen Nationalen Anwendungsdokumenten. Sie sind eine Zusammenfassung aller relevanten Regelungen aus den verschiedenen Eurocodes, nationalen Anpassungen und weiterhin gültigen nationalen Bestimmungen.
Das von der Generaldirektion (DG) XII der Kommission der EU geförderte Projekt umfasst drei Teile: (1) Eine Literaturstudie über mechanische Prüfungen an Gesteinskörnungen, die ergab, dass bei der Festigkeit der Los Angeles-Versuch als Referenzverfahren für Widerstand gegen Zertrümmerung geeignet ist. (2) Eine Serie von Ringanalysen (1993 bis 1997), die 20 Prüfverfahren zu 21 Eigenschaften von Gesteinskörnungen umfasste, unter Beteiligung von rund 50 europäischen Prüfstellen. Zu 19 Ringanalysen wurden ausführliche Berichte erstellt, die eine Beschreibung des Ringversuchs, eine statistische Auswertung einschließlich Versuchsergebnissen und die gewonnenen Präzisionsangaben enthielten. Die Berichte schlugen für einige Verfahren Verbesserungen vor und ermöglichten jeder teilnehmenden Prüfstelle, die eigene Leistung zu kontrollieren. Ein Ringversuch zur Petrographie wurde beschreibend ausgewertet. Ein Überblick über die Prüfverfahren mit dem Versuch einer Wertung ihrer Präzision wurde gegeben: Verfahren mit zufriedenstellender Genauigkeit wurden ebenso aufgezeigt wie solche, bei denen noch Schwierigkeiten vorhanden sind. Faktoren, die zur Streuung der Ergebnisse beitragen, wurden diskutiert und mögliche Verbesserungen vorgeschlagen. (3) Eine Studie über Probenahme unter unterschiedlichen Bedingungen untersuchte den Probenahmefehler, der durch Schwankungen der Produktion sowie durch die Probenahme selbst verursacht wird. 22 Probenahmen, von Transportbändern und verschiedenartigen Halden, die meisten in der Praxis vorkommenden Fälle umfassend, wurden durchgeführt. Die Proben unterschieden sich in Größtkorn, Kornabstufung und Art der Gesteinskörnung. An ihnen wurden insgesamt 575 Siebungen und 958 Ausleseversuche ausgeführt. Die Ergebnisse zeigten, dass, wenn der Probenahmefehler den Fehler des Prüfverfahrens nicht überschreiten soll, Sammelproben aus mindestens 15 Einzelproben bestehen sollten. Im Falle der Probenahme vom Band, die zu bevorzugen ist, stellt eine große Einzelprobe eine annehmbare Alternative dar, sofern die Produktion die Zusammensetzung der Körnung gut kontrolliert.
When the EEVC proposed the full-scale side impact test procedure, it recommended that consideration should be given to an interior headform test in addition. This was to evaluate areas of contact not assessed by the dummy. EEVC Working Group 13 has been researching the parameters of a possible European headform test procedure in four phases. Earlier stages of the research have been presented at previous ESV conferences. The conclusions from these have suggested that the US free motion headform should be used in any European test procedure and that it should be a free flight test, not guided. This research has now culminated in proposals for a European test procedure. This paper presents the proposed EEVC side impact interior headform test procedure, giving the rationale for the test and the first results from the validation phase of the test protocol.
The European Enhanced Vehicle-safety Committee wants to promote the use of more biofidelic child dummies and biomechanical based tolerance limits in regulatory and consumer testing. This study has investigated the feasibility and potential impact of Q-dummies and new injury criteria for child restraint system assessment in frontal impact. European accident statistics have been reviewed for all ECE-R44 CRS groups. For frontal impact, injury measures are recommended for the head, neck, chest and abdomen. Priority of body segment protection depends on the ECE-R44 group. The Q-dummy family is able to reflect these injuries, because of its biofidelity performance and measurement capabilities for these body segments. Currently, the Q0, Q1, Q1.5, Q3 and Q6 are available representing children of 0, 1, 1.5, 3 and 6 years old. These Q-dummies cover almost all dummy weight groups as defined in ECE-R44. Q10, representing a 10 year-old child, is under development. New child dummy injury criteria are under discussion in EEVC WG12. Therefore, the ECE-R44 criteria are assessed by comparing the existing P-dummies and new Q-dummies in ECE-R44 frontal impact sled tests. In total 300 tests covering 30 CRSs of almost all existing child seat categories are performed by 11 European organizations. From this benchmark study, it is concluded that the performance of the Q-dummy family is good with respect to repeatability of the measurement signals and the durability of the dummies. Applying ECE-R44 criteria, the first impression is that results for P- and Q-dummy are similar. For child seat evaluation the potential merits of the Q-dummy family lie in the extra measurement possibilities of these dummies and in the more biofidelic response.
At the 2005 ESV conference, the International Harmonisation of Research Activities (IHRA) side impact working group proposed a 4 part draft test procedure, to form the basis of harmonisation of regulation world-wide and to help advances in car occupant protection. This paper presents the work performed by a European Commission 6th framework project, called APROSYS, an further development and evaluation of the proposed procedure from a European perspective. The 4 parts of the proposed procedure are: - A Mobile Deformable Barrier test; - An oblique Pole side impact test; - Interior headform tests; - Side Out of Position (OOP) tests. Full scale test and modelling work to develop the Advanced European Mobile Deformable Barrier (AE-MDB) further is described, resulting in a recommendation to revise the barrier face to include a bumper beam element. An evaluation of oblique and perpendicular pole tests was made from tests and numerical simulations using ES-2 and WorldSID 50th percentile dummies. It was concluded that an oblique pole test is feasible but that a perpendicular test would be preferable for Europe. The interior headform test protocol was evaluated to assess its repeatability and reproducibility and to solve issues such as the head impact angle and limitation zones. Recommendations for updates to the test protocol are made. Out-of-position (OOP) tests applicable for the European situation were performed, which included additional tests with Child Restraint Systems (CRS) which use is mandatory in Europe. It was concluded that the proposed IHRA OOP tests do cover the worst case situations, but the current test protocol is not ready for regulatory use.
Learner drivers are readied for their participation in motorised transport within the framework of specific, internationally-diverse preparation systems. These systems are historically developed and are characterised by country-specific economic, infrastructural, legal and cultural circumstances. With the aid of functionally-distinguishable teaching and learning methods as well as testing methods, a conceptual framework was created whilst drawing upon research-methodological approaches of comparative political science as well as teaching and learning principles that facilitated a description and analysis of the systems for a comparative observation to be performed. The systems for the preparation of learner drivers in 44 countries are illustrated in the report. The descriptions are based upon surveys of experts from various institutions (ministries of transport, driving instructor associations, testing organisations) as well as upon literary and Internet research. Alongside European countries with a traditional formal driver training, \"Graduated Driver Licensing\" systems that are primarily encountered in English-speaking countries were also taken into account when selecting the countries. They are characterised by the guarantee of gaining comprehensive driving experience under reduced risk conditions in the form of supervised driving prior to the start of independent driving as well as protective special rules for learner drivers whilst gaining further driving experience during the initial phase of independent driving. The results enable a detailed insight into the country-specific structure of learner driver preparation with the components of the formal driver training in driving schools, informal teaching and learning methods such as supervised driving, the driving tests that must be successfully completed as well as legal frameworks and quality assurance measures. The functionality of system components and architectures shall be discussed against the backdrop of evaluation findings regarding the effectiveness in terms of safety.
This paper will outline ETSC's contribution to the European Union's road safety policy 2011-2020. It will present some of the main recommendations from ETSC's Blueprint for the 4th Road Safety Action Programme and will introduce the response to the European Commission's Road Safety Policy Orientations 2011-2020 (published July 2010). The second framework document presented is the Transport White Paper (published March 2011). The paper will focus on new targets and the new vision set for Europe's Road Safety policy picking out some issues in particular such as traffic law enforcement and the protection of vulnerable road users. It will argue that by reinforcing the current Road Safety Policy Orientations, the EU will be better placed to reach its new ambitious goal of halving road deaths by 2020 and the longer term zero casualty vision.
Police records about traffic accidents like used by IRTAD (International Road Traffic and Accident Database) and CARE (Community Road Accident Database) do not represent all road injuries. For instance, road accidents of bicyclists without a counterpart are usually not reported. Furthermore, IRTAD-like data contains hardly any information on injury outcome and accident circumstances. This information gap leads to an under-representation of the safety concerns of the most vulnerable road users like children and the elderly both in accident research and safety promotion. Injury registration for the European Injury Database (IDB), in turn, combines details of accident causation with diagnostic information that can be used to assess injury severity and long term consequences. The IDB is collecting data from hospital emergency department patients and is being implemented in a growing number of countries. In this article IDB results on mode of transport and injury outcome are presented from a sample of nine EU member states.
