Opis:
There are more and more motorcycles on the roads. This can be seen, for example, on the basis of statistical data from the Central Statistical Office, where newly registered two-wheelers are presented. Based on the data, it can be seen that there are more and more newly registered motorcycles every year and that there are many road accidents involving two-wheelers. According to data provided by the WHO, as many as 28% of fatalities in road accidents are motorcycle drivers [10]. The article below presents a review of the literature related to motorcycle crash tests and the dummies used for the tests. The work presents the most important standard that regulates how motorcycle crash tests are performed. The main purpose of the article is to draw attention to the problem of safety of motorcycle users. The text describes various crash tests of two-wheelers and stands used for testing motorcycles. The work presents a dummy specially designed for crash tests involving motorcycles. Differences between this dummy and other dummies used have also been described. The paper discusses the literature and describes research related to crash tests.

Opis:
The selection of a child seat is not an easy task for future parents. Information about child seats, assembly methods, usability and prices affect the purchasing preferences of parents or legal guardians of children. The article contains information about the factors to pay attention to when buying a child seat. The main purpose of the article is to analyze and evaluate information on the selection of a vehicle seat for the right passenger vehicle and child. The article discusses information about the ADAC child seat crash test and the plus test, which are mainly performed for rear-facing child seats.The article presents information on groups of child seats and the method of their installation in a passenger vehicle. The purchasing predispositions of parents and legal guardians in terms of the selection of a child seat were also described. It should be noted that most respondents pay attention to the level of safety of child seats than to their price.

Opis:
25 czerwca 2014 r. w Inowrocławiu już po raz czwarty odbyły się crash testy (testy zderzeniowe) urządzeń infrastruktury drogowej. Po raz pierwszy w Polsce, przy udziale zaproszonych gości i mediów, przeprowadzono także crash test z wykorzystaniem autobusu. Spotkanie zgromadziło ponad 180 osób.
For the fourth time, road infrastructure facilities crash tests were held on 25 June 2014 in Inowrocław. Also a public crash test with the use of a bus was conducted for the first time in Poland, which was observed by guests and the media.

Opis:
The seriousness of an impact "large truck - motor vehicle" has been exhibited. The procedures of truck and motor car s crash testing were compared in order to point out the necessity of car s crashworthiness investigation in terms of compatibility and impacts between vehicles with large difference in mass and rigidity. Furthermore the paper explains a course of frontal impact between large truck and motor car in order to proof the necessity of cars compatibility as well as aggressivity investigation. The mass effect along with rigidity effect was exhibited as well. Moreover, the paper explains the design as well as objectives of the passive safety devices of both motor car and large truck. The concept of another, innovative passive safety device such as "active bumper" has been emphasized. Its working principia, adaptive control as well as the diagrammatically presented design were pointed out. The bumpers control is very difficult as it will be entirely independent from a driver and it has to operate in random condition, therefore, the paper contains a proposition of controlling algorithm of the "active bumper". It also contains explanation of adaptation of the "active bumper" with various working condition as well as consideration of the "active bumper" application with various types of large trucks design.

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:
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:
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.
