Opis:: Shock absorbers in modern cars have asymmetric damping characteristics corrected by overflow valves. Their indicator diagrams are far from being elliptical. Defective shock absorbers may lead to excessive amplitudes in vibration accelerations, excessive car body rolls, both lateral and longitudinal, excessive braking distance and destruction of the car components or road surface. The paper discusses methods of testing shock absorbers mounted or removed from the car. Advantages and disadvantages of the methods are used as bas is for the assessment. It is pointed out that the methods should not assume linear characteristics of springs and damping elements. Testing methods can be divided as follows: - those referring to shock absorbers removed from the car, - those referring to shock absorbers mounted in the car. Methods used for testing shock absorbers removed from the car are those performed on indicator test rigs provided with mechanical-electric or electrohydraulic extortion system. Such test rigs have measuring devices to enable recording of indicator diagrams relative to the absorber damping force in function of piston stroke with deflection and reflection. Among a variety of testing methods, those requiring no removal are by far preferred by Vehicle Control Stations or diagnostic lines. The methods can be divided asfollows: -free vibration type, -forced vibration type.

Opis:: The current accident hazard caused by road transport of goods has been analysed, with the location (road categories) and time circumstances (specific days of the week) having been additionally taken into account. Calculations were done that made it possible to quantify this hazard, which is chiefly caused by the traffic of goods vehicles. The importance of this problem is increasing in the situation of persisting strong and steady upward trend in the traffic of goods vehicles. In a recent period of 10 years, the rate of growth of the traffic of goods vehicles was almost twice as high as that of the traffic of passenger cars. The hazard and fatality risk indicator values were estimated by analysing an isolated set of accident data. The period covered by the analysis of the events that occurred in the road transport of goods extended for the years from 2002 to 2011 and the numerical values have been specified in relation to repeatable week-long periods and to four road categories. The calculated hazard indicator values have been compared with the share of goods vehicles in the whole motor vehicle market, road traffic, and goods transport.

Opis:: Each day more than 3,000 people are killed in the transport system worldwide, most of whom are victims of road accidents. Poland, just like the other EU countries, experiences a disproportion between the number of road accidents and other transport accidents. Each mode has a different safety management system with different databases, transport infrastructure authorities and accident investigation bodies, systems for tracking the movement of vehicles, trains and ships. Although significantly dissimilar, transport modes and their safety management systems can be improved through integration and the use of good national and international practice in the entire transport sector. This is in line with the European Union's policy, which in its 2001 White Paper encouraged member states to undertake work on a European methodology of independent transport safety investigation. ZEUS Project with its aim to build a structure of integrated transport safety system in Poland is an example of the work. International experience shows that an independent investigation agency working across all modes of transportation can most effectively improve safety. An intermodal agency provides economy of operation, transfer of safety lessons between different modes of transportation, the advancement of new and innovative investigation techniques and the ability to focus on key issues of concern in all modes. It is therefore suggested that serious consideration be given to a unified independent agency wherever it is feasible.

Tematy:: safety dimensioning

safety in sea transport
Opis:: The safety of ships involved in the process of transport is one of the most important criteria in the maritime transport. Important factors making up the safety include the technical efficiency of the ship, the qualifications of the people in charge of the ship and the conditions under which the transport process takes a place. The paper focuses on the problems significant and characteristic to the ship traffic safety under uncertainty conditions. The ship safety at supervised traffic requires continuous identification of the navigational situation. Very often safety assessment of the traffic situation is made by examining the relative positions of vessel’s domains. A limitation is that under uncertainty conditions and more than two vessels we have to take into consideration dynamic domains according to the situations of conflicts, which is rather difficult to analyse. One way to assess the traffic safety approximation is analysis of the potentially conflicting situation. Safety in maritime transport can be analysed at the micro level (safety of the ship, the safety of navigation in specific situation mobility) and in terms of macro models (evaluation over time).In the article some problems of fuzzy description of traffic safety in maritime transport are presented. Basic definitions and a stochastic approach to concept of traffic safety in transport are given. The fuzzy approach to stochastic method of dimensioning traffic safety, useful in dynamic traffic control, is proposed.

Opis:: The aim of the paper was to compare the influence of the applied fill on the energy absorbed by the energy ubsorbing structural elements made of composite, steel and from composite with fill foam. The experimental tests were carried out on an INSTRON universal testing machine at the speed rate of the machine's traverse equal 10 mm/min md the numerical analysis has been performed using MSC. Dytran software based on the Finite Element Method. The elements were subjected to axial kinematic loads. The higher specific absorbed energy occurs in the case of energy absorbing elements made of composites and from composite with fill foam. These elements can be applied in structures designed for the protection of people or limitation of the whole structure failure, e.g. in the case of a helicopter or car crash etc. The failure progressing in a relatively uniform manner results in the fact that the work md for failure of an energy absorbing element causes a substantial reduction of the impact load results. Application of energy absorbing elements may be a system dissipating the energy of a car impact into a crash barrier. The results of numerical simulation of stiffness plate hitting to the road barrier are presented. Experimental tests and numerical simulations were also presented for a composite sleeve subjected to progressive failure, which allowed carrying out simulation and analysis of a crash into a road barrier protected by a system of two such sleeves.

Opis:: In the paper the role of human attention in road transport safety was considered. In the first part, various, known in psychology aspects of attention such as: selectiveness, scanning, divided attention, shifting and sustain attention were described. Further, research about drivers attention were characterized. From this perspective, especially significant are data associated with divided attention and selectiveness. It was proved that responding simultaneously to secondary task decreases concentration on driving. In this article, the meaning of individual differences in attentional functioning was emphasized. Empirical data suggests that high generał intelligence subjects have bigger capacity of attention than individuals with low general intelligence. Another factor that influences attention is age. Younger drivers (age 23 - 46) under demanding conditions, such as sohing multiple tasks, perform better than older drivers (age 58 - 76). In the last part the work focuses on circadian rhythms in human attention and their impact on transport safety. Many studies suggest that road accidents exhibit variations with circadian (peak at 03:00), weekly and seasonal period. Besides that, many researchers were interested in dynamics of attentional functioning during the day. Results indicate different patterns of responses with respect to different aspects of attention and chronotype.
W pracy przedstawiono znaczenie uwagi człowieka w bezpieczeństwie transportu drogowego. W pierwszej części zostały omówione różne, spotykane w psychologii, aspekty uwagi takie jak: umiejętność selekcji źródła informacji, zdolność do przeszukiwania pola percepcyjnego, podzielność uwagi, przerzutność oraz przedłużona koncentracja. Następnie zaprezentowane zostały badania nad uwagą u kierowców. W tym zakresie szczególnie istotne wydają się być dane dotyczące podzielności uwagi i selektywności. Wykazano, że wykonywanie dodatkowego zadania towarzyszącego jeździe samochodem obniża koncentrację na prowadzeniu. W artykule pokazano również znaczenie różnic indywidualnych w zakresie uwagi. Badania pokazują, że osoby o wysokiej inteligencji ogólnej mają większą pojemność uwagi, niż osoby o niskiej inteligencji. Innym czynnikiem, który wpływa na uwagę jest wiek. Młodsi kierowcy (w wieku 23 - 46) lepiej funkcjonują w warunkach podwójnego zadania, niż osoby starsze (58 — 76 lat). W ostatniej części pracy skupiono się na dobowych rytmach uwagi. Wiele studiów empirycznych pokazuje, że wypadki drogowe charakteryzują się zarówno dobową (szczyt o godz. 03:00 rano), tygodniową jak i roczną rytmiką. Oprócz tego wielu badaczy zajmowało się zmianami w koncentracji uwagi w ciągu dnia. Wyniki tych badań sugerują inny wzorzec reakcji w zależności od aspektu uwagi oraz chronotypu.

Opis:: The work presented in this paper is the experimental study of square aluminum columns under dynamic axial impact loading. The objective of the study is to evaluate the effect of foam filling to the crushing behaviour of the columns. Four columns were tested, i.e. a single walled column, a single walled column filled with aluminum foam, a double walled column, and a double walled column filled with foam. The single walled column was 55 mm wide and 1.3 mm thick. The double walled column was prepared by inserting a square column of 38 mm wide and 1.15 mm thick inside the single walled column. The column was made of aluminum extruded alloy AA 6063 T1, and the insert material was the closed cell aluminum foam (ALPORAS) with density of 440 kg/m3. The tests were carried out using a dropped weight impact testing machine that had been built specifically for this purpose. The results showed that filling the aluminum foam to the columns increase their crushing resistance force, where the increase is of the singlewalled column is higher than that of the double-walled column. Filling the foam to the columns reduce the high crushing force peak for both columns as well. This experimental results confirm results of other researcher.

Opis:: In today's automotive industry, companies are organized into simultaneous engineering teams to develop their new products. The new way of doing business enables some companies to develop their new products quicker and cheaper with higher quality and reliability. In the past few years there has been the tendency to increase the safety of vehicles by introducing intelligent assistance systems that help the driver to cope with critical driving situations. These functions are characterized by the active control of the driving dynamics by distributed assistance systems, which therefore need a reliable communication network. The faults in the electronic components, which control these functions, are safety-critical. However, the assistance functions deliver only an add-on service in accordance with a fail-safe strategy for the electronic components. If there is any doubt about the correct behaviour of the assistance system, it will be switched off. For by-wire systems, without a mechanical back-up, a new dimension of safety requirements for automotive electronics is reached. After a fault the system has to be fail-tolerant until a safe state is reached. realizing that road vehicles, mostly commercial vehicles taking part over proportionally in accidents, become more and more complex indicates that suitable and adaptable analysis methods are crucial to be applied with appropriate certification body.

Opis:: The paper discusses the need of additional equipment of trucks which are already being in use in Poland with the devices of the indirect visibility which enable to observe much bigger area in the neighbourhood of the vehicle. A large number of accidents are caused by drivers of larger vehicles who are not aware that other road users are very close to or beside their own vehicle. These accidents are often related to a change of direction at crossings, junctions or roundabouts, when drivers fail to detect other road users in the blind spots, which exist in the immediate area around their vehicles. The increase of the indirect visibility from the driver's seat improves safety of the participants in the road traffic. Over 400 people lost their life in the EU in of these accidents. Most of the victims of such accidents are pedestrians or two-wheelers, a particularly vulnerable category of road users. Implementation of the EU Directive 2003/97 (which is obligatory for the new vehicles) to the vehicles earlier registered can be done by replacement and installment of the new mirrors which contain bigger areas. This paper shows the results of the research on the independence of minimum dimensions (s, w) of mirrors class V and its placement on values of radius of curvature. It contains much bigger area than it is due to demands. Author also made a proposition on how to solve the problem of the limited visibility on the inclined crossing of roads and on enlarged crossing while turning left.

Opis:: An increasing amount of carried transport mass, speed of transportation, intensity of traffic pose a threat to the ecosystem are presented. At risk are both the participants of the road and railroad traffic and the inhabitants of areas where those transport tasks are performed. The risk also applies to property and the natural environment - soil, water, air, and fauna. Therefore, providing the transports with high level of safety is of top priority. Assessment of the risk connected with transport of hazardous materials is closely related to evaluation of road traffic rules and their violations. The risk of occurrence of undesirable events during transportation of dangerous material is connected with such events as accidents, collisions, derailments, vehicle failures. Risk assessment of hazardous materials land transportation will make it possible to indicate the factors, which determine occurrence of undesirable events. An analysis of risk in land transport of hazardous materials will be made on the basis of data concerning results of road controls carried out by inspectors of Road Transport Inspection. In this research, an attempt has been made to evaluate the risk connected with land transport of hazardous materials with the use of available risk assessment methods.

Opis:: A vehicle hitting a traffic barrier creates a major threat to traffic safety as a result of displacement of components of the barrier by the forces transferred from the vehicle. We built a theoretical model of the dynamics of such processes and behaviour of concrete barriers set on various types of surfaces. We calculated the displacement as a function of vehicle impact energy and barrier base. We completed analytical approximation for our calculations and we referred the theoretical results to experimental test results. This validated our model of barrier and vehicle movement dynamics as fully qualified for use in the planning of safer barriers and evaluation of barrier effect on traffic. Basing on our calculations, we determined that a second-order polynomial can be used for describing the lateral displacement of a barrier placed on various types of surfaces for a wide range of impact energies (actually, from O to 120 kJ). The courses of the approximating function represent an efficient model for determining the maximum lateral displacement of a concrete barrier on impact of a B or C segment vehicle.

Opis:: Transport is one of the major and economically most important branches of industry that provides employment opportunities and welfare for population. However, despite beneficial aspects that come together with transport development, it is often associated with potential threat to people's health and lives. It is needless to say that road safety has a great influence on society mobility. Out of all branches of industry, wad transport is considered to be the most dangerous. Such conclusions are drawn on the basis of statistics according to which the greatest numbers of people die in road accidents. Analysing the data gathered in given period, it can be estimated that more 90 per cent of the whole number of fatalities died in road accidents. Constantly increasing amount of incoming automotive vehicles as well as outdated road injrastructure in Poland contributes to the growth of various security threats connected with road transport. Due to the facts mentioned above, it is necessary to introduce important changes that would help to modify present road infrastructure and arrangement so that they are adjusted to continuously expanding transportation demands and needs. Therefore, the following changes shall be paid additional attention: quality ofroad infrastructure. Therefore, particular attention should be paid to the changes that are to be introduced. Such steps of modification aim at road infrastructure quality enhancement, improvement of the highway code, stricter requirements of different means of transport technical condition and changes concerning country transportation policy approach. These ideas are expected to result in increased road safety.

Opis:: The necessity of rationalization of construction machine operation and maintenance processes results in development of computer diagnostic systems. Use of diagnostic systems in operation and maintenance of machines is conditioned by the accepted strategy of operation. The current method of operation with a view of the Resurs is characterized by: set the assigned operating area specific use, implementation of the agreed duration of maintenance, prioritization of maintenance. Dates and ranges of maintenance adopted in the implementation of this strategy are fixed, based on the results of years of research supplies and are independent of the state of the machine. Prioritize ongoing maintenance and repair means that the service or repair of higher-order includes the following ranges of operation, lower maintenance row. In this work there has been made an attempt to evaluate the level of threat connected with failure to perform a transport task by a technical object. Data for the assessment was obtained on the basis of information collected from used telematic systems diagnosing continuously the state of tested technical objects. In this work there has been made a survey of normalized risk assessments methods. On this basis, FMEA method has been used for risk assessment connected with failure to perform a task by the analyzed objects.

Opis:: The aim of the paper is to present the main guidelines of the Safeway2School European research project. The project's primary objective is to determine the safest route for school buses that transport children to school, through low traffic density areas, avoiding black spots. The project anticipates the use of Intelligent Transport Systems (ITS) in the process of children transportation. Within the project the Route Planning System, Rerouting System and Warning System will be designed and developed for school buses as well as for all surrounding vehicles. Project aims at designing the route for school buses and also the alternative route (in case the bus has to be rerouted due to traffic congestion or traffic incident) in order to maximize the safety of transported children with the use of localization and route planning tools, on-board safety systems and sensors in vehicles and road infrastructure. It is also crucial to design the network of ,"intelligent" bus stops (child-bus stop-bus communication) and equip the pilot group of children with special tags. The target group of the project consists of school bus drivers, children (pupils 6-16 years old) and their families, but also the road infrastructure authorities, car manufacturers, other road users and representatives of public administration. Within the project the training programs for school bus drivers, children, parents and other drivers will be elaborated. The aim of such activities is to result in unification of guidelines, training schemes and regulations concerning safe transportation of children to school. For the pilot realization of the above mentioned systems and training programs four European localizations have been chosen: Sweden, Austria, Italy and Poland. At the end of the project realization an evaluation of usability and effectiveness of applied technologies, as well as the level of system user's acceptance will be conducted. The project was submitted to the European Commission within the 7th Frame Program. Motor Transport Institute is the Polish project executor.

Opis:: Safety of transport is the main goal of transportation systems to achieve. This is of crucial importance for the road transportation as the number of used transport means is constantly increasing which involves a rise in the number of used vehicles and an increase in the intensity of traffic, especially in urban areas. Obviously, actions aiming at reducing the number of road collisions and protecting people involved in those events have been taken. These actions are taken both by vehicle designers both active and passive safety systems, as well as road traffic engineers who are responsible for actions aiming at increasing the safety level of transport infrastructure through implementation of Intelligent Transportation Systems. Although there are more and more modern engineering solutions in the fields of vehicle design and road traffic, it is still the human who is the weakest link of the socio-technical system, including the system of road transportation. For this reason, the authors of this work have made an attempt to analyze the undesirable impact of transport means on the safety of transport tasks. The experimental tests have been performed within a real system of municipal public transportation to illustrate a transportation system exposed to changing conditions of road traffic during twenty-four hours.
