In the past ten years, InAs/InAsSb type-II superlattice has emerged as a promising technology for high-temperature mid-wave infrared photodetector. Nevertheless, transport properties are still poorly understood in this type of material. In this paper, optical and electro-optical measurements have been realised on InAs/InAsSb type-II superlattice midwave infrared photodetectors. Quantum efficiency of 50% is measured at 150 K, on the front side illumination and simple pass configuration. Absorption measurement, as well as lifetime measurement are used to theoretically calculate the quantum efficiency thanks to Hovel’s equation. Diffusion length values have been extracted from this model ranging from 1.55 μm at 90 K to 7.44 μm at 200 K. Hole mobility values, deduced from both diffusion length and lifetime measurements, varied from 3.64 cm²/Vs at 90 K to 37.7 cm²/Vs at 200 K. The authors then discuss the hole diffusion length and mobility variations within temperature and try to identify the intrinsic transport mechanisms involved in the superlattice structure.

Niemal każda z zapytanych przez Polski Instytut Transportu Drogowego oraz Grupę Inelo - firm transportowych odnotowała w ostatnim roku wzrost kosztów prowadzenia działalności (98 proc.). Co istotne, wśród badanych przedstawcieli transportu, aż 6 na 10 musiało się zmierzyć ze wzrostem na poziomie od 26 do nawet 50 proc. Powód? Bez wątpienia jednym z nich jest wysoka inflacja. Zaobserwowano także zwiększające się opóźnienia w płatnościach za świadczone przez firmy transportowe usługi. Jak wygląda polski transport z perspektywy ubiegłego roku i jak kształtował się popyt na usługi przewozowe? Czy w dlugofalowym ujęciu branża TSL poradziła sobie z wyzwaniami. Kondycję transportu drogowego prześwietlono w raporcie "Branżometr Inelo. Inflacja - czas wyzwań dla branży TSL"

In the transportation systems are different types of intersections. Among them, roundabouts are considered the safest solution. The application of roundabouts is conditioned by many factors. One of them borders on area development. Roundabouts, among others, are localized in important city places, thus serve as a landmark in the city or are localized on the boundaries of areas with different communication functions, thus constituting an organizational landscape feature. Sometimes, they diversify the space of a street or close the perspective of a monotonous street. Hence, beyond the basic functions, roundabouts with the appropriate central island arrangements can also play the function of organizing the architecture of the local area. The ways and possibilities of roundabout central island arrangements are presented in this article. An interesting central island arrangement shows that roundabouts play an esthetic and organizing landscaping role.

The austenitic 316L steel (1.4401) is an important stainless material used to build various means of transport. Austenitic steel has high resistance to atmospheric corrosion. The austenitic steel is treated as a good weldable material, although cracks are possible. This paper analyses the influence of various MIG welding parameters on the creation of correct joints used in the stainless steel structures of mobile platforms elements, as an example of welding structures, in various means of transport. Various tests verifying the mechanical properties of MIG welds, including non-destructive tests, tensile strength and hardness tests, were carried out. This article aims to show how important and complex the task is to select the correct welding parameters for elements of means of transport made of austenitic steel on the example of elements of mobile platforms.

For many years in many Western Europe countries, cycling has been associated with not only recreation and tourism but has equally gained an important function as a means of transport used in everyday commuting to work, study and entertainment. The bicycle appears to be a very good alternative to motor vehicles that produce exhaust fumes and create congestion on road transport networks. Not only is the bicycle environmentally friendly and takes up little space in road transport networks, but also, the time of bicycle travel is often competitive in relation to travel made by private car or public transport. This article presents the characteristics of the bicycle infrastructure and services offered in selected cities in the world and Poland, as well as the issues of bicycle counters as sources of data on bicycle traffic volume, along with an exemplary analysis of this type of data.

Today, route planning requires freight forwarders to make a conscious effort to identify unloading points such that the transport process is both cost- and time-efficient. At the same time, operational parameters that help to determine the validity of the chosen route must also be considered. This article aims to present the key metrics and ways of attaining them to provide a reliable determination of a transport company’s performance. Based on a selected transport company, the authors collected data on the transport routes implemented in 2020. Interpretation and analysis of the extracted information of the concerned sections were carried out and followed by alternatives. We present in this article the results of research concerning the exploitation parameters of the vehicle set. The evaluation of a given route section was indicated using selected indicators adapted to the specificity of the enterprise. The results are aimed at locating the components that have a destructive impact on the entire process. The proposed solutions serve to introduce factors that will pave way for improving the services provided. An in-depth analysis of all sections and key parameters was performed. Because of the conducted studies, abnormal parameters were identified, efficient sections were distinguished and new routes were developed in the case of previous routes that were not highly efficient and which had a possible alternative corridor. The obtained results of the research can comprise, for logistics managers, vital elements in the transport process, to which attention should be given in the course of overseeing these processes.

Vibration diagnostics is of particular importance in rail transport safety systems because the signals received from vibration sensors installed on rolling stock, bridges, tunnels, and other infrastructure objects have great diagnostic information potential. Despite this, in practice, there are cases when the adequacy of the results of the vibration control and diagnostics task is not ensured. The reason is that the sampling step of the vibration signal does not change when the train speed changes. Given the need to change the sampling interval depending on the train speed, this article proposes an adaptive technology for vibration signal sampling that allows the building of intelligent systems of adaptive vibration control of malfunctions in rail transport.

Using the notion of isolated urban islands, this paper discusses, from a theoretical point of view, three important but controversial issues related to the measurement of social exclusion in the big cities: (i) the extent to which social exclusion is likely to occur, (ii) accessibility indicators that are sensitive and relevant for the evaluation of social exclusion, and (iii) the geographical scale for evaluation. From an urban island point of view, two important issues have been raised: the distribution of jobs, basic facilities, and services within an urban island and the travels of people between urban islands. Therefore, social exclusion can be determined either by the affordability/acceptability of travel time/cost to access the minimum requirement of facilities/services or the number of facilities/services in reach of the individuals within acceptable/affordable travel time and cost. A person will be at risk of social exclusion if they belong to a minority group as opposed to the majority in the same society. Some levels of social exclusion risk have been proposed. The evaluation should be implemented at the meso-level (urban island). From the view of the urban islands, the issues of transportrelated social exclusion are clearly understood, and measurements of social exclusion should be solved. We feel that a detailed survey/interview is needed for areas at high risk of social exclusion, followed by an evaluation at the micro-level to identify excluded people and the causes for their exclusion. It is expected that this paper will attract researchers to pay more attention to this issue.

Stainless steel could be treated as the main material used to construct various means of transport, including mobile platforms and tank trucks. An austenitic steel known as 316L steel (1.4401) has high resistance to atmospheric corrosion, natural waters, water vapor, alkaline solutions, and acids, even at elevated temperatures. This steel is weldable, although it is also prone to various types of welding cracks. Many factors influence the quality and mechanical properties of a joint. The most significant of these is the appropriate selection of welding parameters, which should be determined precisely and separately for each type of sheet, depending on its thickness and geometric features. The aim of the present article is to study the influence of main TIG (Tungsten inert gas) welding parameters on the creation of proper joints used in the construction of mobile truck platforms or tank trucks. The proper selection of parameters enables the production of welds with good functional properties. A novelty of this article is the proposal to weld each layer of a thick joint with different parameters, which has an important influence on the mechanical properties of the joint. It is expected that the new material and technological solution will yield a joint with good corrosion resistance and increased mechanical properties. This is important in the responsible construction of means of transport, using the example of mobile platforms and tank trucks. Different tests verifying the properties of joints, including non-destructive testing, tensile strength tests, and fatigue tests, as well as a hardness probe, were applied.

The integration of Ukraine’s economy into the European space requires the dynamic and balanced development of all its sectors, especially the transport sector. The purpose of the research is to identify the factors related to transport entrepreneurship that affect the economic development of Ukraine, in particular regarding the formation of added value (gross regional product). The paper presents the author’s definition of transport entrepreneurship as an independent, systematic, and risky entrepreneurial activity in providing transport services. The results revealed a negative trend in the formation of the added value of the transport enterprises of Ukraine, both in terms of value and as a percentage of GDP. This prompted the authors to determine the factors affecting the formation of gross added value (gross regional product) by transport enterprises of Ukraine to further develop proposals aimed at their activation. Four models were created in the first stage of the research to achieve the goal. These models are based on gross regional product in transport, warehousing, postal and courier activities; gross regional product in transport, warehousing, and postal and courier activities per capita; gross value added in transport, warehousing, and postal and courier activities; and gross value added in transport, warehousing, and postal and courier activities per capita. In the second stage of the research, the fifth model with the highest correlation coefficients was built, which made it possible to identify the factors of negative and positive influence on the formation of gross added value (gross regional product) by transport enterprises in Ukraine. Based on the results, a number of measures are proposed to stimulate factors of positive influence and neutralize negative influence. The proposed tools for identifying the factors related to transport entrepreneurship that affect the economic development of Ukraine can serve as markers for the formation of the country’s post-war strategy in the field of transport entrepreneurship.

W artykule przedstawiono metodykę prognozowania przewozów towarowych kolejowych i drogowych w oparciu o wskaźniki makroekonomiczne, jakimi są wartości dodane poszczególnych gałęzi gospodarki. Wielkości wartości dodanych określają rolę danej gałęzi gospodarki w tworzeniu PKB. W przypadku gałęzi gospodarki uznanych za transportochłonne, mogą określać również zapotrzebowanie na przewozy poszczególnych grup ładunków. Istnieje możliwość prognozowania rocznych przewozów towarowych w rozpatrywanym horyzoncie czasowym w oparciu o szacunkowe wskaźniki zmian przewozów, w zależności od oszacowanych zmian wielkości wartości dodanej poszczególnych gałęzi transportu określonych jako transportochłonne, przy czym zmiany przewozów transportem lądowym są określane oddzielnie dla zdefiniowanych grup ładunków w zależności od przyporządkowanych im gałęzi gospodarki. Przewozy towarowe transportem kolejowym w danym roku, w poszczególnych grupach ładunków, zostały określane jako udział transportu kolejowego w przewozach towarowych transportem lądowym. Wskaźniki udziału transportu kolejowego są również funkcją zmian wielkości wartości dodanych poszczególnych gałęzi gospodarki. W artykule przedstawiono także metodykę określania funkcji elastyczności, zarówno dla zmian przewozów w poszczególnych grupach ładunków, jak również udziału transportu kolejowego w przewozach towarowych transportem lądowym. Metoda może być wykorzystana przy opracowaniu prognoz na cele dokumentacji studialnej dotyczącej infrastruktury transportowej.

The article presents a methodology for forecasting railway and road transport of goods based on macroeconomic factors which are the values added of specific sectors of the economy. The amounts of values added determine the role of a particular sector of the economy in creating GDP. In the case of sectors considered to be transport-intensive, they may also specify the demand for transport of particular groups of goods. It is possible to forecast the annual freight transport in the considered time period based on the estimated rates of changes in transport depending on the estimated changes in the values added of individual transport modes defined as transport-intensive. Changes in the land transport are specified separately for defined groups of goods depending on the economic sectors to which they are assigned. Railway transport of goods in a specific year in each specific groups of goods is defined as the share of railway transport in freight land transport. Railway transport share indexes are also a function of changes in the amount of value added by each sector of the economy. The paper also presents a methodology for defining flexibility function for both changes in transport in specific groups of goods as well as the share of railway transport in the land freight transport. The methodology can be used in developing forecasts for transportation infrastructure feasibility studies documentation.

Opisano rozwiązania infrastrukturalne i organizacyjne pozwalające na optymalne wykorzystanie posiadanego taboru oraz minimalizujące uciążliwości dla pasażerów. Szczegółowo przedstawiono modelowanie układu komunikacyjnego przy budowie trasy tramwajowej do Naramowic, przebudowie Ronda Rataje oraz realizacji Projektu Centrum. Opisane rozwiązania, często nietypowe lub dotychczas niewykorzystywane w miejskim transporcie zbiorowym, w dużej mierze pokazały, że przy dużej ilości ograniczeń w możliwości wykorzystania istniejącej infrastruktury należy szukać rozwiązań nieszablonowych. Organizator i operator miejskiego transportu zbiorowego wyszli w Poznaniu poza utarte schematy, co pozwoliło zachować atrakcyjność transportu zbiorowego działającego przy narzuconych przez prowadzone inwestycje ograniczeniach.

The article presents the functioning of public transport in Poznań in the period of infrastructure investments carried out in recent years. Infrastructural and organisational solutions allowing for optimal utilisation of the existing rolling stock and minimising inconvenience for passengers are described. The modelling of the transport system during the construction of the tram route to Naramowice, the reconstruction of Rondo Rataje and the implementation of the Centre Project (Projekt Centrum) is presented in detail. The solutions described, often atypical or hitherto unused in urban public transport, largely demonstrated that, given the large number of restrictions on the possibility of using existing infrastructure, non-conventional solutions should be sought. The organiser and operator of urban public transport in Poznań went beyond the usual schemes, which made it possible to maintain the attractiveness of public transport operating within the constraints imposed by the investments carried out.

Węzłem przesiadkowym określa się miejsce wyposażone w odpowiednią infrastrukturę umożliwiającą zmianę środka transportu. W dużym mieście, takim jak Kraków, praktycznie nie jest możliwe wykonywanie podróży komunikacją miejską z pominięciem węzłów przesiadkowych. Są to bardzo istotne miejsca ze względu na funkcjonowanie całego systemu transportowego. W części I (TMiR nr 3/2022) przedstawiono metodykę wieloaspektowej oceny wskaźnikowej AMPTI. Aktualna wersja obejmuje 10 wskaźników ilościowych, które pozwalają na przeprowadzenie rozbudowanej analizy węzłów. Metodyka ta została wykorzystana do oceny dwóch węzłów przesiadkowych funkcjonujących w Krakowie, tj. Rondo Grunwaldzkie oraz Podgórze SKA. Pierwszy integruje komunikację autobusową i tramwajową, a drugi komunikację autobusową, tramwajową, ale także kolejową. W części I przedstawiono również szczegółową charakterystykę obu węzłów. Oprócz wykonania audytu węzłów (niezbędnego do oceny wskaźnikowej), przedstawiono także wyniki pomiarów liczby pasażerów wsiadających i wysiadających w węzłach. W części II przedstawiono wyniki ankiety wśród pasażerów korzystających z węzła, służącej ocenie wygody przejścia pomiędzy poszczególnymi przystankami w węźle oraz poziomu dostępnej informacji pasażerskiej oraz relacji dokonywanych przesiadek.. Przedstawiono również wyniki oceny obu węzłów metodą AMPTI. Wyniki zestawiono tak, aby sprawdzić jak funkcjonuje węzeł wyposażony w komunikację autobusową, tramwajową oraz kolejową w porównaniu z węzłem integrującym tylko komunikacją autobusową z tramwajową.

Interchange node is a place equipped with appropriate infrastructure enabling a change of means of transport. In a large city such as Kraków, it is practically impossible to travel by public transport without interchanges. Therefore, they are very important places due to the operating in the entire transport system. Part I (TMiR No. 3/2022) has presented the methodology of the AMPTI multi-faceted indicator assessment. The current version includes 10 quantitative indicators that allow for an extensive analysis of nodes. This methodology was used to evaluate two interchange nodes operating in Kraków, ie Rondo Grunwaldzkie and Podgórze SKA. The first integrates bus and tram transport, and the second integrates bus, tram and rail transport. Part I has also presented detailed characteristics of both nodes. In addition to the audit of interchanges (necessary for the index assessment), the following was also carried out: measurement of the number of passengers getting on and off at interchanges. Part II (TMiR No. 4/2022) presents the results of a survey of passengers using the interchange to assess the convenience of the transition between the various stops at the interchange and the level of passenger information available and the transfer connections that are made. The results of the AMPTI evaluation of both interchanges are also presented. The test results have been compared for both nodes in order to check how the node equipped with bus, tram and rail communication operates in comparison with the node integrating only the bus and tram transport.

The problem of disability affects more and more people every year. One of the obstacles to their proper functioning are everyday problems connected with mobility. The aim of this article is to find out the opinion of disabled people living in Northern Wielkopolska on the quality of infrastructure, its adaptation and accessibility for the disabled as well as to present improvements which would enable disabled people to use public transport services safely, freely and comfortably. On the basis of the survey, it may be concluded that the basic problem of road infrastructure from the point of view of people with disabilities is the low quality of access to stops, roads, pavements and high kerbs, poor adaptation of public space or very wide transport and lack of reconstruction of some places and road fragments. Added to this is the average quality of adaptation of public transport for people with disabilities.
