The article deals with quantification of human movement within the vehicle rolling over ramp-like object. One of the yet unsolved issues relating to vehicle passive safety is the difference between movement of crash test dummies and living occupants. The research in this area thus must be in following years focused on quantification of this movement with goal of obtaining applicable data. One of the first researches performed in this area is described in the article where vast part is devoted to the description of test parameters. The end part is then devoted to the movement quantification using angular momentum of occupant upper body. The result of the performed test was acknowledgment that human within rollover is able resist to this vehicle movement within whole first quarterturn of vehicle rotation at least up to angular velocity of approx. 1,6 rad/s.

The transport of dangerous goods requires specific knowledge of the safety procedures connected with transported materials, its composition, chemical and physical properties. It includes a "know how" on the field of neutralization of potential leakage and secured means to be maintained during the transport by routes. The article points at the monitoring systems responsible for security of cargo and vehicles themselves, and describes the use of GPS, GSM and ICT systems to track movements of dangerous cargo. Combination of mentioned technologies, guarantees fast reaction in case of sudden breakdown or even a catastrophe.
The motorcyclist’s body motion following a motorcycle impact against a motor car side is determined by a system of forces and reactions acting on the rider’s body. An analysis of this motion was carried out, based on a research experiment. The related measurements and calculations were taken as a basis for an analysis of the dynamic loads; they also indicated the type and scope of the bodily injuries that may be incurred by the motorcyclist during a road accident. Based on the research experiment, the trajectory of motorcyclist’s head and torso and the course of contact between the motorcyclist’s body and the car were determined. The acceleration values having been obtained from the measurements were used for determining the displacements and changes in the angular position of motorcyclist’s head and torso. The research experiment confirmed the motorcyclist’s head to be the part of his/her body that undergoes the highest accelerations. The system of forces and reactions acting on motorcyclist’s body at the initial stage of the motion under consideration may lead to a situation dangerous to the motorcyclist where his/her head hits the edge of the car roof.

W artykule opisano założenia, jakie dla państw członkowskich opracowała Organizacja Narodów Zjednoczonych w zakresie bezpieczeństwa ruchu drogowego na lata 2011–2020, w tzw. Dekadzie BRD. W dokumencie ONZ pt. "Plan Globalny" wskazano na 5 filarów programów bezpieczeństwa ruchu, dotyczących: zarządzania brd, uczestnika ruchu, pojazdu, infrastruktury oraz ratownictwa, w oparciu o które kraje powinny konstruować swoje narodowe rezolucje. Na przykładzie pięciu państw z różnych kontynentów przedstawiono sposób realizacji tej międzynarodowej rezolucji. Bliższe poznanie różnych strategii poprawy bezpieczeństwa ruchu drogowego może pomóc w wyborze właściwych działań w tworzonym obecnie w Polsce Krajowym Programie Bezpieczeństwa Ruchu Drogowego, zastępującym dotychczasowy program GAMBIT.

Premises concerning road traffic safety 2011-2020 (so called Road Traffic Safety Decade) prepared for member states by the United Nations are described in the article. In the UN document entitled: "Global plan" 5 pillars of programs of road traffic safety have been indicated: management of road traffic safety, traffic participant, vehicle, infrastructure and traffic rescue service on which should be based national resolutions. On the examples of 5 states from different continents the method of realization of this international resolution has been presented. Acquaintance with different strategies for improvement of road traffic safety may help to choose suitable measures for the National Programme for Road Traffic Safety that is being created right now in Poland to replace previous GAMBIT programme.
W artykule przedstawiono koncepcję modelu monitorowania ruchu drogowego. Przyjęto założenie, że wejściem będą dane z sieci punktów wideodetekcji (węzłów) zapisane w macierzy natężeń ruchu. Wyjściem modelu będą dane o strumieniach pojazdów pomiędzy badanymi węzłami. W celu weryfikacji modelu oraz optymalizacji rozmieszczenia punktów wideodetekcji zaproponowano standardowy system monitorowania złożony z kamery wyposażonej w moduł ANPR oraz komputer PC.

The paper presents a concept of a statistical model of road traffic monitoring. Input data is collected from a network of videodetection posts and placed into road traffic intensity matrices. Model outputs consist of road traffic stream data between defined traffic nodes. In order to verify the model assumptions and optimize the positions of videodetection posts an ANPR based monitoring system is proposed.
In the article, three types of proximity sensors that might be used in bicycle rangefinder to measure the distance between the bicycle and an overtaking car are compared. The influence of various factors on the accuracy of the distance measurements obtained using ultrasonic, infrared and laser sensors is tested, among others, light conditions, car surface type and colour, rain, pollination and vibrations.
Considerations presented in the paper have been based upon the analysis of tendencies of computer science developement in management. On the basis of this there have been laid out the main directions of computer science application development in road traffic management in Poland.
There are a number of ways to measure transport of which kilometres travelled is the most frequent macro indicator (at country level). It is used to estimate projected fuel consumption, potential number of vehicles, amount and type of exhaust fumes emissions and the number of road accidents and casualties. The paper presents macro models of vehicle kilometres travelled, built on the basis of data from some fifty countries worldwide. Next, the resulting model was calibrated for the conditions in Poland.
The article presents the psychological conditioning of working in the profession of a driver. Important features of the psychological tests described in the transport regulations and other aspects important for road safety are indicated. Being familiar with these conditions is necessary not only for transport psychologists but also for trainers, and drivers preparing themselves to work as professionals.
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.

The safety of buses in road traffic is very important because of potential hazards of peoples' life and health, damage and loss of freight and high costs of crash effects. The technical state of all vehicles has been examined during required periodical inspections, but in spite of this, the technical conditions of large number of vehicles have been poor. The range of inspections and their frequency have been determined according to the law of each country. The methodology and frequency has been determined in accordance with domestic legislation. The methodology of technical inspections concerns only some important systems of vehicles but not all. For example, anti-lock systems, retarders, adaptive cruise control systems, speed limitation devices etc. have not been examined. The results of examinations of 120 buses and coaches have been presented in this paper. Tests were carried out in scope of securing safety in road traffic. The methodology of compulsory periodical inspections was applied during initial tests. Vehicles were examined on typical control stands and in road tests. A special methodology for road tests for coaches with anti-lock systems was elaborated. Additional checks were carried out in cases when the results of basic tests were unsatisfactory. More than 50 vehicles of the total number of examined buses were faulty.
