transport system effectiveness
Opis:
The freight transport combines the issue of supply services organization for various types of entities, including large shopping centres, stores of various industries, restaurants, work and leisure places, small-scale outlets, or municipal waste shipments. Due to the location of customers, transport services encounter many difficulties related to infrastructural constraints and increased traffic. This adversely affects the safety and obstructions in traffic and air pollution and thus is a disturbing factor for the lives of inhabitants. There is also a growing problem of the smog in large cities (in Poland, for example, Warsaw or Cracow). Traffic safety, minimization of congestion, and minimization of environmental pollution by transport activities are of particular importance in the development of freight traffic organization plans. In connection with the above, in recent years, the use of Environmentally Friendly Vehicles (EFV) in various spheres of human activity has been dynamically developing, and this concerns the cargo transport. Currently, vehicle manufacturers are providing an increasing number of delivery vehicles and trucks. On the other hand, entrepreneurs planning to implement pro-environmental solutions face a decision problem related to the efficiency of a transport system based on the use of EFV as well as the economic validity of implementing this type of innovation. In connection with the above, in this article, the problem of the impact of transport on the environment and the use of EFV in the freight transport was analysed. The main issues related to the functioning of the transport system and its negative impact on the environment has been presented. Environmental friendly vehicles and their parameters have been characterized. The main decision problems in organizing the transport system, also in the context of the use of EFV, have been identified and analysed. Finally, an example of a model for assessing the efficiency of a transport system with an emphasis on its impact on the environment was presented. The article was concluded with the summary of considerations and the proposal for further work.

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:
This paper discusses the current directions of vehicle developments, as well as the barriers and opportunities for using electric vehicles instead of conventional vehicles. There is also mentioned a problem of the battery charging system. Compared to refueling gasoline powered vehicles, charging of battery electric vehicles takes considerably more time, which renders a single-purpose charging infrastructure inconvenient. However, an objective of this article is also to investigate the future market prospects of various types of EVs, with the economics of EVs in comparison to conventional cars. Only if the final driving costs can be considerably reduced will EVs gain significant market shares.

Opis:
Electronic payment systems used for urban services are implemented and funded by the public sector. Those are rather big investments, characterized by high costs, but they also allow for gaining profits – mainly connected with the transport offer optimization and with more effective price management. When preparing the documents, among other papers concerning functionality or technical and technological solutions, it is necessary to prepare a feasibility study, in which the assessment of the effectiveness of such investments is an important part. To do so, one ought to identify and assess the costs and the profits connected with the realization of such projects. Such assessment ought to be performed within the frame of financial analyses (from the perspective of the unit implementing and using the solutions) and of economic analyses within which the external costs and profits should also be considered.
