The development of airport security screening systems requires the use of increasingly sophisticated and effective equipment to detect prohibited or hazardous items and substances. However, this can lead to a reduction in the throughput of the security checkpoint (SCP). This paper addresses the operationally important problem of the dilemma between screening effectiveness and screening checkpoint throughput, which is important to the real operational capabilities of an airport. In this paper, a comparison of traditional walk-through metal detectors (WTMD) gates and newer technology body scanners (BSs) was carried out in terms of SCP throughput as an element determining the operational capabilities of the airport. For this purpose, a simulation model was developed to study throughput based on a colored timed Petri net. The analysis showed that, depending on the characteristics of the available staff, the level of terrorist and epidemic threat, as well as the time of year, it is advantageous to use different strategies to vary the size of the stream of passengers directed for screening by the WTMD gate and BS.

Transportation accessibility for people with disabilities is the challenge of our time. In Poland, there are more than 3 million people with disabilities who have legal proof of disability. In reality, there are many more - from 4 to as many as 7 million. Thus, there is a need to actively include this group of people in social life, including in the area of public transportation. This work aims to present issues related to the accessibility of integrated interchanges for people with special needs. The work also points to a key issue for transport system managers related to and aggregation of knowledge necessary to implement the changes in transport infrastructure. Information about the needs of people with disabilities is, in turn, a prerequisite for proper universal design, which is already becoming noticeable in many areas of social and economic life. As technology evolves, so do the methods of obtaining information about the needs of people with disabilities. The difficulty here, however, is to develop tools that take into account the degree of disability of the specific people from whom we would like to obtain information. The authors in the paper justify, on the one hand, measures that aim to eliminate the difficulties that a person with special needs may encounter when traveling by various means of transportation, and on the other hand, point to certain solutions and tools that are used to acquire knowledge that will consequently allow the precise adaptation of the current infrastructure to the needs precisely defined by these people. The aggregation of knowledge also has additional significance in terms of increasing transportation accessibility for people with disabilities. It enables the informed design of new facilities and supporting infrastructure to take into account the changing needs of people with disabilities.

Dostępność transportowa dla osób z niepełnosprawnością jest wyzwaniem naszych czasów. W Polsce osób z niepełnosprawnościami, które mają prawne potwierdzenie niepełnosprawności, jest ponad 3 mln. W rzeczywistości jest ich dużo więcej - od 4 do nawet 7 mln. Zachodzi więc konieczność aktywnego włączenia tej grupy osób do życia społecznego, również w obszarze transportu publicznego. Niniejsza praca ma na celu przedstawienie problematyki związanej z dostępnością zintegrowanych węzłów przesiadkowych dla osób o szczególnych potrzebach. Praca wskazuje również na kluczowe dla zarządzających systemami transportowymi zagadnienie związanie oraz agregacją wiedzy koniecznej do wdrożenia niezbędnych zmian w infrastrukturze transportowej. Informacje o potrzebach osób z niepełnosprawnościami są z kolei warunkiem właściwego projektowania uniwersalnego, które staje się już zauważalne w wielu obszarach życia społecznego i gospodarczego. W miarę rozwoju technologicznego, zmieniają się również metody pozyskiwania informacji o potrzebach osób z niepełnosprawnościami. Trudnością tutaj jest jednak opracowanie narzędzi, które uwzględnią stopień niepełnosprawności konkretnych osób, od których informację chcielibyśmy uzyskać. Autorzy w pracy uzasadniają z jednej strony działania, które zmierzają do eliminacji utrudnień, z jakimi może się spotkać osoba ze szczególnymi potrzebami podczas podróży różnymi środkami transportu, z drugiej strony wskazują na pewne rozwiązania i narzędzia, które służą do pozyskiwania wiedzy, pozwalającej w konsekwencji na precyzyjne dostosowanie bieżącej infrastruktury do ściśle określonych prze te osoby potrzeb. Agregacja wiedzy ma także dodatkowe znaczenie w zakresie zwiększenia dostępności transportowej dla osób z niepełnosprawnością. Umożliwia ona świadome projektowanie nowych obiektów i infrastruktury towarzyszącej z uwzględnieniem zmieniających się potrzeb osób z niepełnosprawnościami.

The transport process consists of many stages, where many interferences and problems may occur. It is important to identify these problems and find solutions to them, for example, using innovative tools supporting transport process management. A properly organised transport process allows the entire supply chain to function properly. For a transport process to be effective, it must be appropriately coordinated from planning, organising, implementing and controlling. In each of these phases, different types of problems may be encountered; therefore, the persons responsible for the various phases must monitor them closely. By reacting quickly, they can resolve any interference, so that the whole supply chain runs without major problems. The organisation of transport processes consists of several phases, which are an integral part of the whole process. Properly trained staff, knowledge of the transport market and the needs of the customer are essential for a company to function properly. Thanks to these three components, a company can offer services at the highest level. This work aims to develop a scheme of the transport process on the international market and also identify problems occurring in the organisation of transport processes. Some solutions to existing problems are also proposed.

In recent years, the development of IT systems for fleet monitoring was observed. Tire pressure monitoring systems are constantly improved. Decreased values in tire pressure can cause deformation of tires. Monitoring of tire pressure is an important function in oversized transport trucks. Tire pressure and rolling resistant influence fuel consumption. The purpose of this paper was to determine the impact of tire pressure on fuel consumption in a fleet of trucks with tire pressure monitoring system installed and to determine the impact of other factors that may affect fuel consumption, such as the vehicle weight, brake usage and cruise control usage. The results of the research were developed using a multiple regression model describing the above dependence.
