Opis:: Safety is a priority criterion of the transport systems operation referred to as a total of means and activities connected with carrying of people and cargo. The main goal of systems of this typ e is safe carrying people in set quantities and over an assigned area, by means of transport means used in the system. Road transport is the most frequently used branch of transport. It is characterized by high speed and flexibility of transport tasks accomplishment resulting from a big number of roads which enable carrying passengers or cargo directly to the place of destination. Road transport can be distinguished from other transport branches by the following features: unlimited access to road transport means, high serviceability, high transport speed, providing services according to the schedule andpunctually. The system environment includes all components which belong to it in terms of the carried out analysis. External factors of the environment, due to a system approach to the analyzed system safety assessment include: weather conditions, road surface, inappropriately designed infrastructure, kinds of roads. The paper identifies the source of safety threats of transport systems caused by the influence of weather conditions on people and technical means of transport.

Opis:: An anthropo-technical system is a pair Human -Technical Object performing their tasks in the environment E . In systems of this type threats can be posed by a human H, technical object TO, and the environmental impact on the technical object and people present within the system or its environment. The level of undesirable influence of the human factor on safety of the system operation depends on the human location in the analyzed system. In the work there has been madę an attempt to develop a method for assessment of undesirable errors of people situated in an anthropo-technical system and its environment. Error is an inseparable attribute of human behaviour. Depending on the situation, a human error can lead to deviations from the terms of task accomplishment, it can threaten their safety and be the cause of an undesirable event occurrence. Errors can be divided into the following groups: Training errors these are errors connected with the technique of vehicle driving, decision errors which in situations posing a threat to the system safety largely depend on the situation assessment, making and following a decision of rational control of the vehicle, and Information reception errors resulting from failing to notice signals informing about operation of the vehicle particular subsystems or a change of the road conditions or noticing them too late. For this purpose an algorithm of assessment of people 's undesirable actions has been developed. The proposed method for assessment of the impact of undesirable actions of people involved in an antropo-technical system and its environment is a complex method which accountsfor different human behaviours.

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:: As far as the current rules involved in business enterprise operation process are concerned, one of the most significant characteristics is specified by the need of engaging economic criterion in all procedures involved. Thus, it is required to introduce deep and extensive analysis concerning economic aspects ofpassenger transport. First of all, it is essential to specify currently existing demand for passenger transport service and compare it in relation to the supply capabilities offered by a transport enterprise. Business advantages created by the enterprise are also necessary to be considered and analysed. The basis for transport enterprise operation should be provided with order placed by Passenger Transport Executive, subcontracting firm of a chosen line according to valid schedule including both, rush and after-rush hours. In order to avoid any possible difficulties it is very important that the hired company is informed about all factors influencing economic efficiency of the serviced bus line. As a result, subcontractor is enabledto make right decisions and eliminate potential problems. Important processes having a considerable influence on proper functioning and effectiveness of public means of transport are connected with its usage, diagnosing and making it fitness for use. Operation effectiveness aspects that are the most frequently discussed in professional literature is described as relations existing between the profits and the input. It takes form of difference or quotient of the values mentioned above. This paper presents evaluation and analysis method controlling different means of transport operation system effectiveness. Method developed with the aim of analysing and evaluating public means of transport operation effectiveness, provides managerial staff with feedback, which is helpful as far as taking right decisions, is concerned. Making proper choices has a great influence on the process and it bears the responsibility for functioning of the system in terms of reliability and cost efficacy. Certainly, the more professional service is, the more satisfied customers are. Moreover, customer demands are more likely to be met, which means that all involved procedures related with functioning of the system are carried out in the accordance with regulations and reguirements, being currently inforce.

Opis:: The transport system are sociotechnical systems in which the direct realization of the tasks is dealt with by an executive subsystem consisting of the elementary subsystems of a human - a technical object (an operator - a means of transport) type realizing the tasks within the system environment. In respect of a human located within a transport system the most significant criterion in the evaluation of the transports being realized is their safety. The safety level of the task realization is influenced by the risks resulting from the interaction of the forcing factors, affecting an elementary executive subsystem. These factors may be divided into [8]: working, External, antropotechnical. In order to structure safety evaluation model of the road transport system we need to: build the algorithm for evaluating safety of analysed system, establish safety criterion for the system's performance, structure a model using the algorithm of safety evaluation of the system. Due to the complexity of the systems being analysed in the paper, it has been attempted to evaluate the influence of the forcing factors on the safety of this system operation.

Opis:: Systems of public transport carry out their tasks on the territory of a given town and in the suburbs performing the same functions as in towns. A distinctive feature of this type of system is performance of its task for twenty four hours, in different traffic intensity conditions over an assigned administrative area. This type of variables has a large influence on occurrence of undesirable events (failure of vehicles and their devastation, collision and accidents). In the work, an attempt of identification of undesirable events occurring in the analyzed transport system has been made. Moreover, an analysis has been made which covers one day of the week, time of the day and weather conditions in which particular events took place. Another aspect of the work was to make an analysis of the vehicle driver's age, job experience and a given hour of work on the day of the event occurrence. Obtainment of such data allowed demonstrating the structure of events according to the criterion of the event type, and costs connected with bringing the damaged transport means to the state of serviceability. The obtained results of experimental tests provide a basis for taking rational decisions by decision makers employed in a given system. These decisions are supposed to reduce the number of undesirable events occurrence and costs connected with them.

Opis:: The study deals with operation quality assessment of operating complex systems especially transport ones. It has been established that assessment of their operation quality depends on fulfilment level of specified criteria. Thus, determination of a set of criteria in terms of their quantity and significance is of great importance. Since the considerations refer to socio-technical systems of the type: human machine and environment , and especially municipal transport systems, these criteria account for human actions, machine operation (transport means) and the impact of factors coming from the environment. The basis of their operation quality is provided by a set of significant, variable in time, measurable and independent features whose values, in a given time period, determine the fulfilment degree of the specified criteria. .On the basis of fulfilment degree of the distinguished criteria, an assessment of operation quality and classification of the considered transport systems are made. In this study, one way of choosing the criteria has been proposed. This method is based on square matrixes and questionnaire survey, which are usedfor establishing their influence on the transport system operation quality, for selected transport means, used in urban complexes.

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.

Opis:: The article deals with an issue of complex systems operation efficiency, especially of the ones which are connected with transport. The operation of such systems aims at developing both passenger and load transportation in terms of safety, reliability, effectiveness and environment friendliness. These properties should be researched in a particular place and time that were earlier planned and selected. Operation effectiveness is an important component ofwidely understood social-economic and technological research, including assessment of the considered transport system. The concepts of operation efficiency, most frequently used in literature, express it as the relation between benefits (treated as profit or income in terms of economy) and costs. However, a ratio of two quantities, the flrst of which is evaluated positively, that is, aims at reaching the highest values and the other one being negative, is considered as the most important definition of efficiency. In some cases these quantities can assume constant values, treated as basic ones. It should be remembered, though, that in many cases the system goals are formulated in different terms than, e.g. economic ones. And the systems should be evaluated taking into consideration the goal achievement degree. The article deals with an analysis of distinguished values of selected assessment indices for an investigated transport system, and on this basis an assessment of the transport system operation efficiency, in a given period of time, has been made.

Opis:: Continuous and dynamic development of freight transports, especially in the road sector, results in generation of negative effects on the environment and poses hazards to human health and life and by generating high costs it creates significant economic, social and environmental problems. Therefore, it is necessary to take actions aiming at promotion of development of sustainable and efficient transport systems, integrating different transport branches and technologies. Such requirements are fulfilled by the subsystem of inter-mode transport system, that is, combined transport which is an alternative for a traditional road transport, and can also play a very important role in achieving goals of the European policy for sustainable development of transport. Its promotion can largely contribute to solving present and future problems connected with transport in Europe through relieving excessively loaded roads from a certain portion of freight transports which will result in improvement in the traffic safety and reduction of its negative impact on the humans and the environment. Providing high quality of inter-mode transport operation, especially in terms of reliability, punctuality, safety and keeping delivery terms depends on the infrastructure state, modern equipment of terminals and efficiency and effectiveness of their functioning. It should be emphasized that promoting inter-mode transport provides social benefits on a big scale as shifting a part of international road transports into a combined one inter-mode can have a significant influence on reduction of the road transport external harmful effects. In this paper, there has been made an analysis and assessment of inter-mode transports in Poland, taking into consideration the motor and railway (linear and point) infrastructure. Also, a suggestion concerning the location and construction of terminals for the service of inter-mode transports has been considered. Moreover, a technical-economic analysis of implementation of the discussed solution purposefulness has been made as well.

Opis:: This paper deals with selected problems connected with transport means operation quality. Basic concepts concerning the problems of quality have been defined, and general characteristics of the elaborated methodology have been made. Description of rules on the basis of which the method was elaborated, has been presented. An algorithm of mathematical model determination has been created and a model for quality assessment of the system operation has been built. This model is supposed to serve as a general abstract form for operation quality assessment of a wide class of real transport systems different in terms of their features, structure and operation. The further part of the paper deals with possibilities of quality control in order to provide the desired level of the transport system operation quality which will be an effect of the carried out research, especially, the results, obtained on the basis of the proposed assessment method. The presented methodology can be found to be a universal tool for diagnostic, prognostic processes, and above all, for optimization and rational control ofcomplex systems of technical object using, especially transport ones through assessment of their states, determined on the basis of changes of significant features characteristic for the system.

Opis:: This paper presents theoretical basis for evaluation of the transport system operation quality. A general evaluation model was built, and further part of the paper is to consider the theme of damageability of the means of transport, as a reliability feature, constituting one of the most important criterion to evaluate the transport system operation. Based on the analysed references in question as well as on the results of our own research it has been found that the damages to the means of transport, being utilised within the transport systems, are a result of interaction of various forcing factors. Some number of the damages results from natural wear of the means of transport elements, which is a natural phenomenon, while the remaining damages may be caused by an inefficient repair of the previous damage. This leads to so called secondary damages to the repaired element, occurred within a short time interval, which is a proof of inappropriate organization of the repairs, poor training level of the repairing teams, limits related to pre and after repair diagnosis, which directly affects reliability of the means of transport and consequently the operation quality of the transport systems in which they are being operated and maintained. Based on the analysis of the investigation results it has been found that the primary damages are independent on one another and they occur randomly. The secondary damages are dependent, because their occurrence depends on prior occurrence of the primary damage and the effect of its improper repair or improper repair of the next secondary damage.

Opis:: This study presents an analysis and evaluation of application of European Car Modular Systems in the Polish road transport. Those systems and respective terminology have been analysed and classified. Application of such systems in other countries of the European Union has been described. SWAT analysis has also been carried out in order to enable the most optimal choice of modular system in freight transport to match the condition and characteristics of the Polish road infrastructure. The systems have also been analysed in terms of efficiency and the analysis was performed on the basis of a selected research object – a transport company. An analysis of costs and estimated profits from transport services to be provided by those systems has been carried out on the basis of the research object in comparison with costs borne by the considered company with currently used transport means. This study shows that taking into consideration the results of analyses, safety aspect, road infrastructure and energy efficiency of the vehicles it was found that the proposed oversized vehicles could be implemented to be used on the Polish roads. The analyses and tests performed for a transport logistic company discussed in this article have demonstrated that the proposed modular systems will undoubtedly allow reducing significantly the costs of transport services by increasing load capacity of vehicles.
