Opis:
Celem artykułu jest przedstawienie istotności wykorzystania platform symulacyjnych w celu poprawy bezpieczeństwa uczestników ruchu drogowego oraz analizy zagadnień ogólnie związanych z obszarem bezpieczeństwa wewnętrznego. Przyczynkiem do tej dyskusji jest wprowadzenie modelu ciała człowieka na potrzeby programu CYBID V-SIM będącego elementem szerszej platformy symulacyjnej. Autorzy przedstawiają przykłady badań z zakresu bezpieczeństwa drogowego, w których platformy symulacyjne były wykorzystywane. Wskazane są powody stojące za koniecznością dalszego rozwoju platform symulacyjnych. Jako podsumowanie, na bazie doświadczeń z symulacyjnych badań zagranicznych, autorzy odnotowują, że istnieje duży potencjał we współpracy służb oraz środowisk naukowych. Taka współpraca mogłaby służyć np. celom utworzenia polskiej szczegółowej bazy danych o wypadkach drogowych, uwzględniającej informacje o obrażeniach przydatne z punktu widzenia biomechaniki zderzeń oraz medycyny sądowej, a także edukacji społecznej.
The aim of the article is to present the importance of using simulation platforms for improving road user safety as well as other analyses in the area of civil safety. The subject was inspired by the introduction of a human body model to the CYBID V-SIM simulation package. The authors present examples of studies from the road safety area wherein simulation packages were used. The rationale behind the need for further development of simulation platforms is presented. As a summary, based on prior studies from abroad, the authors conclude that there is major potential in the collaboration between the public service sector and scientific communities. Such collaboration could lead to the development of a Polish in-depth road crash database, which would contain data useful from the point of view of crash biomechanics and forensic medicine, and could aid in public education.

Road crashes remain an important public health issue. This study aimed to assess the perceived importance of four types of measures for reducing traffic crash rates. For this cross-sectional study, data were obtained from a national sample of 1,200 Spanish drivers responding to a telephone-assisted survey. The most valued types of road safety measures were those related to users’ training/education and infrastructural improvements. Further, individual perceptions were influenced by both demographic and trip-related factors. The results of this study support the idea that user features remain a relevant issue to consider when developing and implementing road safety measures.

Opis:
This article attempts to determine the possibility of identifying an explosion on board an aircraft based on the scattered remains. To reach this goal, a detailed analysis of reports on aviation accidents was performed in the context of the scattering of remains at various crash sites. Moreover, explosions cause an emission of large amounts of hot gases at supersonic speeds, which is the main source of destruction. The destruction is quite characteristic and depends on the material subjected to damage. It allows for the unequivocal identification of an explosion. The performed analysis and conclusions confirmed the thesis set forth in the article that, by means of analyzing the scattered remains after a plane crash, it is possible to determine, with high probability, whether an explosion occurred on board during the flight, which could be the cause of the event. This way of initially determining the causes of accidents would allow for targeting further accident investigation methodology and improving the workflows for teams investigating plane crashes.

Opis:
Traffic safety is influenced, among other factors, by characteristics of the roads, which include the width of the shoulder. Shoulder width was noted to have a large effect on crash frequency, as well as on traffic speed. In this paper, we focused on paved shoulders. Previous studies confirmed that increasing the width of the paved shoulder is associated with a decrease in crash frequency. However, wider shoulders may encourage higher driving speed, which is related to an increase of impact speed and crash severity – this issue was hypothesized, but not statistically investigated. Thus, conclusions based on crashes and speeds contradict each other, and there is no simple answer to the question of the safety impact of wide shoulders. To address this gap, we analyzed a sample of two most typical categories of Czech secondary roads, which differ only in the paved shoulder width (S9.5 roads with 0.75m-wide shoulder, and S11.5 roads with 1.75m-wide shoulder) and thus present a suitable example for studying the safety impact of paved shoulder width. We used generalized linear models of crash frequency, and multinomial logistic models of crash severity (separately for single-vehicle and multi-vehicle crashes), as well as a statistical test of differences in speed for the two road categories. The results showed that: Firstly, there were fewer crashes on S11.5 roads compared to S9.5 roads; this was true for both single-vehicle and multi-vehicle crashes. Secondly, single-vehicle crashes on S11.5 roads were more severe compared to S9.5 roads; the change of severity in multi-vehicle crashes was not statistically significant. Thirdly, driving speeds on S11.5 roads were approx. by 7 km/h higher compared to S9.5 roads. These findings support the hypothesis of an association between wider shoulders, higher speeds, and increased crash severity, especially in the case of single-vehicle crashes. As a practical solution, various speed management measures, including widening to a 2+1 road, may be recommended.

Opis:
Nowadays trends related to the road safety make the lighting poles producers meet rigorous requirements that decrease the risk of death and injury of vehicle drivers in case of the impact. New requirements are in force from 1 January 2015, when Road and Bridge Research Institute informed that each pole liable to a direct vehicle impact has to meet Standard PN-EN 12767. The article presents the design of a novel, safe lighting pole. The novelty lies in the pole simplicity, which results in the manufacturing technology the cost of which is comparable to that of the conventional pole. Compared to the conventional poles of thickness 3 mm and greater, this one is made of thin-walled steel sheet of increased strength parameters and specially designed sleeve that is fixed to the base plate. The crash tests carried out on the track for the impact experiments proved that the requirements of the standards in the driver highest safety class and in the high vehicle kinetic energy absorption were satisfied both for the speed impact 35 km/h and 100 km/h. The numerical model for simulations of the vehicle behaviour during and after the impact was implemented in software Ansys LS-Dyna. The simplifications of some elements were of negligible influence on the analysed phenomena. The comparative parameters were ASI, THIV and exit velocity of the vehicle. The numerical results were close to the empirical ones, therefore they confirmed that finite element analysis can be successfully applied at the stage of elaborating of the initial concepts of the road lightning poles. It follows that the number of expensive crash tests can be reduced.

Opis:
One major problem associated with gliding is the safety of the crew during landings in the country outside the airfield. The analysis of glider-accident statistics shows that such out-landings may significantly influence the safety. Therefore, of vital importance are the crashworthiness properties of the glider fuselage structure. The subject of the study was the PW-5 glider fuselage made of composites and subjected to high loads typical of glider crashes. The aim was to provide experimental data for validation of a numerical model of the cockpit-pilot system during impact. Two experimental tests with the composite glider cockpit were performed using a typical car-crash track. During the first test the cockpit with a dummy inside was crashed onto the ground at the angle of 45 degrees at a speed of 55 km/h. Accelerations and deformations at chosen points in the cockpit as well as signals coming from the dummy sensors and forces in the seat belts were recorded. The second test was an impact into a concrete wall at a speed of about 80 km/h. The full-scale tests were accompanied by a number of quasi-static and dynamic laboratory tests on samples of composite material. The experimental tests provided valuable results for the parametrical identification of a simulation model developed using the MADYMO software.

Opis:
Highway guardrail is a kind of important road traffic safety facility. When a vehicle is travelling on a highway, it can lose control because of accident. The guardrail can prevent the vehicle from rushing directly out of the road, so as to reduce the injury to the driver in the vehicle. Therefore, the guiding performance, anti-collision performance and buffer performance of the guardrail are important indexes to reflect the highway guardrail safety in the traffic accidents between vehicle and guardrail. The process of collisions between vehicles and guardrails is a complex motion, affected by multiple factors such as the movement patterns and types of vehicles, the types of guardrail, the bending stiffness of the beams, the speed of collision, the angle of collision, etc. The accuracy of energy estimation when vehicle collides with guardrail is the foundation of highway guardrail design, installation and improvement. Many experts and scholars at home and abroad have done a lot of theoretical research and experimental verifications on the safety performance of highway guardrail, and analyzed the anti-collision ability and energy absorption effect of highway guardrail. Single degree of freedom model is the most widely used mathematical model of vehicle collision in highway guardrail. The traditional model is more suitable for calculating the maximum impact force of small vehicles, but it is not accurate for large vehicles. However, due to the unreasonableness of the model in the theoretical derivation process, there is a large error in the mathematical model, especially in estimating the accuracy of the energy value of the large vehicle collision guardrail. Practice shows that the current guardrail cannot withstand the impact of large vehicles. Once large vehicles collide with the corrugated beam guardrail, the guardrail will collapse in most cases, and the vehicle will rush out of the road directly, so it is very difficult to exert the protective function of the guardrail. The anti-collision performance of guardrail is poor, which is related to the existing calculation model, which results in insufficient strength in the design of guardrail.

This study investigated the deterrence effect of the police patrol on the road safety in China and the research purpose was achieved by questionnaire survey and data regression. Firstly, a questionnaire survey was carried out to investigate the drivers’ illegal behaviours and attitudes to safety measures, such as police patrol, surveillance cameras and warning signs, and 137 drivers participated in the survey; the statistical results showed that 45.3%, 4.4% and 16.8% of the respondents had the experience of speeding, driving under influencing of alcohol and fatigued driving respectively; all of the participants believed that traffic police patrol would change their dangerous driving behaviours and police patrol is most effective among three road safety measures based on the investigations. Secondly, data about police patrol frequency and road crash rate on the road segment was collected from the local Transportation Administration Bureau and the regression analysis based on the data was conducted to investigate the direct effect of traffic police patrol on road safety improvement. The results indicated that increasing the frequency of police patrol has an obvious positive effect on improving the road safety and it is consistent with the results from self-reported questionnaire survey.

Opis:
The work presents the results of crash tests carried out with six electrical car models (from 2012-2013), with the weight of 1200-2300 kg (Smart Electric Driver, Mitsubishi IMiEV, Nissan Leaf, CODA, Ford Focus BEV, Tesla Model S). The results were published on the Internet by the National Highway Traffic Safety Administration (USA), and the tests involved a car travelling at the speed of 56 km/h, hitting frontally into a non-deformable (stiff) barrier, positioned perpendicularly to the car’s direction of movement. Particular attention was paid to the deformation of the car after hitting the barrier, so-called stiffness characteristics of the frontal crumple zone, and to the loads on the dummies placed at the driver’s and passenger’s seat (Hybrid III, a 50-centile man and a 5-centile woman). Results of the tests with electric cars were compared with the results of the tests with over a hundred of combustion engine cars with similar weight and type of car body (sedan, hatchback). The tests proved that, in the majority of electrical cars tested, the deformation of the frontal crumple zone after hitting an obstacle is larger than in case of similar cars with internal combustion engine. Because of that, the dynamic loads on the occupants of the vehicle tend to be smaller, as indicated by measured loads on the heads and chests of the dummies. The results may suggest that the frontal crumple zone may be better constructed in the case of electric cars, while the design possibilities regarding that area are limited in standard cars due to the combustion engine, which is not deformed during the accident, which makes it more difficult for the energy of the crash to dissipate.

Opis:
The study concerns a selected road safety barrier consisting of a B-type guiderail, Sigma-100 posts with 2.00 m spacing, and supporting elements of a trapezoid cross section, located between the posts and the guiderail. The barrier is formed on a horizontal concave arc having a radius of 150 m. The full-scale experimental TB32 crash test was carried out for a vehicle impacting at the angle of 20°, on the testing grounds of the Automotive Industry Institute, Warsaw, Poland. The numerical modelling and simulation methodology of a barrier – vehicle system, recently developed by the authors is applied. Simulation of the above test was performed using LS-Dyna v.971 finite element code, while maintaining the conditions of the experimental test. All the functionality parameters for the barrier are studied, among others, ASI, THIV, working width, vehicle motion trajectory in the exit box. The results of the simulation tests were compared with those of the full-scale experimental test. The experimental verification of the numerical modelling and simulation of the selected crash test is rated positively. It was proven, both numerically and experimentally, that the TB32 crash test does not meet the condition imposed on the vehicle motion trajectory in the exit box.
Przedmiotem badań numerycznych i eksperymentalnych jest stalowa taśmowa drogowa bariera ochronna, składająca się z prowadnicy typu B, słupków Sigma-100 w odstępach 2,00 m oraz elementów podporowych. Bariera jest w łuku poziomym wklęsłym o promieniu 150 m. Test zderzeniowy TB32 według PN-EN 1317 przeprowadzono na poligonie Przemysłowego Instytutu Motoryzacji w Warszawie, z użyciem samochodu Dodge Neon. Zastosowano metodologię modelowania numerycznego i symulacji układu bariera – pojazd opracowaną przez część zespołu autorów. Symulację ww. testu zderzeniowego przeprowadzono przy zastosowaniu systemu LS-Dyna v.971, przy zachowaniu warunków testu eksperymentalnego. Analizą objęto wszystkie parametry funkcjonalności bariery określone w normie PN-EN 1317, m.in. ASI, THIV, szerokość pracująca, trajektoria ruchu pojazdu w polu wyjścia. Przeprowadzono weryfikację eksperymentalną modelowania numerycznego i symulacji testu TB32. Wynik weryfikacji oceniono pozytywnie. Udowodniono, zarówno numerycznie, jak i eksperymentalnie, że w rozpatrywanym przypadku bariery w łuku poziomym test TB32 nie spełnia kryterium pola wyjścia pojazdu.
