Opis:: The article concerns the application of data, collected by mobile devices, in models road maps needed in virtual environments. Recently, a system has been developed at UTH Radom, with the aim of tracking wanted vehicles. The simulation of such vehicles, understood as units with driver or passenger(s), the acquisition and transfer of related data as well as the processing of information obtained from observation cameras, are subject of ongoing research. A key component for an effective analysis of trajectories, are detailed digital road maps. Given the lack of access to commercial geo-information systems, the compilation of customized digital maps for the territory of interest, using open data collections of geographical data, is essential for research in the public sector. In the present paper, the adaptation of chosen Openstreetmap data structures to the described purposes is presented.

Opis:: Process of designing of vehicle suspension as a combination of springs and dampers is a very complicated task. In general it requires designing system respecting good ride comfort and good handling at the same time. It is obvious that these two aspects are dependent also of the type of the road on which vehicle is riding. Especially it is important in city buses which are workplaces for bus drivers and each day are transporting thousands of people. Bus suspension system is quite different from car suspension. Because of the mass and size instead of traditional springs, pneumatics springs are used. In some cases, values of damping and stiffness of the spring are adjusted to the proper road in a real bus while driving. It is necessary nowadays to have a virtual assessment that can simulate "bus suspension behaviour" to abstracted suspension parameters such as springs and dampers characteristics. In this paper a multibody model of city bus suspension has been presented. Multibody models are the best way of simulation of dynamic behaviour of the vehicle. Simulations showing how different types of the road affect the structure of the vehicle have been performed. Such prepared model can be then use as an input for optimization of the bus suspension in terms of ride comfort, handling, or even passengers' safety.

Opis:: Road safety is an important social issue. Hence, changes in road traffic rules have a large influence on travel safety improvement. One of the major issues to be addressed is the speed limit of motor vehicles and radar speed measurements. Moreover, road traffic rules impose the obligation to wear safety belts during driving, carrying children in car safety seats and they put a ban on drink driving as well as driving under the influence of other intoxicating substances that have a negative influence on the driver’s physical condition and driving skills. This study analyses changes in traffic rules and provides assessment of the way they affect road traffic safety in Poland. The study presents an analysis of the issues connected with road vehicle operation and safety of the passengers including: wearing safety seat belts, use of children car safety seats, vehicle lighting, speed limit. Such issues as the proposed changes in breathalyzer use and implementation of safety systems to provide road users with safety have been addressed.

Opis:: The work considers changes occurred in the features of the supporting structure in three categories of cars, namely: with the self-supporting body, framed body an intermediate structures between these two solutions. The area of analysis includes the length of deformation (crush) of the front al part of the car after collision with a rigid obstacle (barrier). The range of deformation is a significant factor of the passive car safety and indicates the efficiency of fulfilling the protective function for the passengers. The work shows absolute and relative (percentage and unit) variations of the car deformation, depending on the year of manufacture, including the period of 1980 - 2010. Marked trend lines indicated general nature of the deformation range variations together with the improvement of the car supporting system structures. The course of the trend line has been calculated on the basis of average deformation length values, calculated in defined periods of vehicle manufacture. Selected sections of time result from the division of the period of analysis 1980 - 2010 into six parts. The analysis of the deformation length of the frontal part of passenger cars, SUVs and pickups has been combined with simultaneous evaluation of total car length variations and their weight values. The car weight directly affects the kinetic energy of the impact so it has a significant influence on the range of deformation of the car front during collision with an obstacle.

Opis:: Human body motion during a road accident usually results from the effect of forces of inertia. The analysis of that motion, particularly displacements towards the vehicle interior have significant practical aspect as it facilitates conclusions concerning the mechanisms of danger and injury formation. At the same time, the analysis provides direct indications regarding the improvement of passive safety equipment. The paper presents the time-space diagrams of motion of dummy’s head, neck, torso and hips – the driver of a frame chassis vehicle, identified on the basis of results of the measurements registered in frontal barrier impact and the frame-by-frame analysis of videos recorded during the course of experiment. Courses of these diagrams were associated with acceleration measurement results and forces affecting the parts of the dummy. The experiment showed the complex nature of the influence on the dummy caused by the forces of inertia after a collision of the vehicle with an barrier, vehicle body motion against the frame, reactions in the safety belts, friction on a seat and contact reaction of the vehicle interior equipment. At the same time, it presented the possibilities of indicating the courses of speed variations and dummy displacement as well as significant limitations of calculation possibilities that result from a fact that the process of the impact on the vehicle interior elements is hard to describe.

Opis:: Największy udział w zaspokajaniu potrzeb transportowych w przewozach ładunków w Polsce i Europie ma transport samochodowy. Udział ten systematycznie rośnie, towarzysząc wzrostowi ogółu przewozów. W 2005 roku udział transportu samochodowego w pracy przewozowej wykonanej przez polskie przedsiębiorstwa w transporcie ładunków ogółem wyniósł 52,5%, natomiast w 2011 roku wartość ta wzrosła do 69,9%. W ostatnich latach zauważyć można dynamiczny rozwój elektronicznych giełd transportowych oraz platform przetargowych oferowanych dla branży transportowej. W artykule opisane zostały zasady ich funkcjonowania, a także korzyści i zagrożenia wynikające z ich użytkowania. Dokonano przeglądu dostępnych serwisów oraz charakterystyki wybranych.
Polish motor transport market is characterized by a high level of supply-side subjective dispersion. In 2011, more than 25,000 motor transport enterprises engaged in the international transport of goods were recorded in the country, of which approximately 90% were the entities whose car park did not exceed ten vehicles. The use of traditional tools of contact with transport companies in order to select a specific carrier (e.g. trade catalogs, phone, or fax) can make it difficult to reach satisfactory offers, increasing the operating costs of business activity. Necessary arrangements enabling the sharing of information on the market are provided by the electronic B2B market (business-to-business). Online tools increase the possibility of reaching a large number of customers and provide better adaptation of the agreements to the current needs. Most frequently these are the directories ofoffers with the possibility of performing various searches (e.g. Keyword Search), auction services, and online platforms enabling the conclusion of the short-or long-term contracts. In recent years, we could also observe a dynamic growth of the online freight exchanges, and tender transport platforms. This paper describes the principles of operation of such tools and the benefits and risks associated with their use. There has also been a review and characterization of a selection of sites.

Opis:: The test results indicate that in many structural solutions of the passenger cars, dynamic loads of the rear seat passengers can be significantly higher compared to the front seat passengers, so the risk of injuries is higher for them. The work specifies examples of courses of dynamic loads that occur during the frontal collision with an obstacle and that affect the front seat and the rear seat passengers. At the same time, the attention is paid to relations between a seat occupied in a car and the probability of injuries in various road accidents. The analysis of dynamic loads that affect the rear seat passengers in many cars has been carried out. In order to do that, the laboratory test (crash test) results have been used. Dynamic loads affecting the passengers of various anthropometrical features have been considered. The results of those analyses have been referred to the loads affecting a driver and a front seat passenger, that is the persons who drive a car and are protected by typical passive safety systems on the front seats. The indexes of biomechanical human body resistance to impact load results have been used during the evaluation.
Wyniki badań pokazują, że w wielu rozwiązaniach konstrukcyjnych samochodów osobowych, obciążenia dynamiczne pasażerów na tylnych siedzeniach mogą być znacznie większe niż osób na przednich fotelach, a więc i ryzyko obrażeń jest dla nich wyższe. W pracy zestawiono przykładowe przebiegi obciążeń dynamicznych, powstających podczas czołowego uderzenia w przeszkodę i które działają na osoby jadące w pierwszym i drugim rzędzie foteli samochodowych. Jednocześnie zwrócono uwagę na relacje między miejscem zajmowanym w samochodzie a prawdopodobieństwem odniesienia obrażeń w różnych wypadkach drogowych. Przeprowadzono analizę obciążeń dynamicznych, jakie działają na osoby na tylnych siedzeniach w wielu samochodach. W tym celu wykorzystano wyniki badań laboratoryjnych (testów zderzeniowych) samochodów. Rozważono obciążenia dynamiczne działające na pasażerów o różnych cechach antropometrycznych. Wyniki tych analiz odniesiono do obciążeń działających na kierowcę i pasażera obok kierowcy, a więc do osób jadących, które są chronione przez typowe systemy bezpieczeństwa biernego na przednich fotelach. Podczas oceny wykorzystano wskaźnika biomechanicznej odporności ciała człowieka na skutki obciążeń udarowych.
