Opis:
In contrast to traditional systems for monitoring fault of the running gear of the rolling stock, this paper proposes a technology of noise control at the onset of defects. The authors consider the possibility of creating an intelligent system that can perform noise diagnostics with the indication of the beginning of the latent period of the initiation of typical defects preceding faults. To this end, using the noise technology, sets of reference informative attributes are created in the training process. The reference sets, in turn, are used to determine the condition of the object at the beginning of the development of defects by comparing them with current noise estimates. It also allows controlling the dynamics of the development of defects.

Opis:
The paper addresses the sensitivity of a novel method for quantifying the environmental risks associated with the current-driven transport of adverse impacts released from offshore sources (e.g. ship traffic) with respect to the spatial resolution of the underlying hydrodynamic model. The risk is evaluated as the probability of particles released in different sea areas hitting the coast and in terms of the time after which the hit occurs (particle age) on the basis of a statistical analysis of large sets of 10-day long Lagrangian trajectories calculated for 1987–1991 for the Gulf of Finland, the Baltic Sea. The relevant 2D maps are calculated using the OAAS model with spatial resolutions of 2, 1 and 0.5 nautical miles (nm) and with identical initial, boundary and forcing conditions from the Rossby Centre 3D hydrodynamic model (RCO, Swedish Meteorological and Hydrological Institute). The spatially averaged values of the probability and particle age display hardly any dependence on the resolution. They both reach almost identical stationary levels (0.67–0.69 and ca 5.3 days respectively) after a few years of simulations. Also, the spatial distributions of the relevant fields are qualitatively similar for all resolutions. In contrast, the optimum locations for fairways depend substantially on the resolution, whereas the results for the 2 nm model differ considerably from those obtained using finer-resolutionmodels. It is concluded that eddy-permitting models with a grid step exceeding half the local baroclinic Rossby radius are suitable for a quick check of whether or not any potential gain from this method is feasible, whereas higher-resolution simulations with eddy-resolving models are necessary for detailed planning. The asymptotic values of the average probability and particle age are suggested as an indicator of the potential gain from the method in question and also as a new measure of the vulnerability of the nearshore of water bodies to offshore traffic accidents.

Opis:
The aim of this paper is to develop a quantile method of cost analysis allowing identification of the most cost-generating malfunctions occurring in a fleet of public transport vehicles. The exemplification of this method has been performed for a fleet of a specified type of trams. The idea behind the quantile method of public transport vehicle operating cost analysis is the reversing of the accumulated function of costs, for the determination of which a cost database from a given operating time of a public transport vehicle fleet has been used. The paper presents data on the malfunctions from the first five years of operation of trams in a large transport company. The assumed time of five years results from the warranty period provided by the manufacturer. The recorded number of indexes of replaced parts was 547. The group contained inoperative parts that were renewed several times.

Opis:
The determinants of mode choice of interregional transport of fish, which is highly perishable, vastly differ from that of other commodities. These determinants are to be identified to improve transport efficiency. A questionnaire survey of shippers is used to collect the data. Highly correlated observed variables are combined to form four latent factors by factor analysis to reduce the errors in modelling. Logical relations among the component variables of latent factors are perceived, and mathematical formulations are used to estimate new variables. It is found that transportation costs and shipment weight contributes to factor 1, while distance contributes to factor 2. However, transportation costs are associated with distance and shipment weight. Thus, the variable, transportation cost per q-km, is estimated. Survey respondents' attitudes are also incorporated into modelling by including qualitative factors obtained by the factor analysis of shippers' preference ratings. A latent class analysis confirmed the existence of heterogeneity among shippers. Misrepresentations of effects occur in modelling if the heterogeneity in the data is not considered. No studies have found the best combination of observed variables, latent factors, estimated variables, and qualitative factors, considering shippers' heterogeneity in freight mode choice. Hence, this study is done to find the optimum modelling strategy. Modelling revealed that models built with estimated variables outperformed those built with latent factors. Including qualitative factors along with observed variables and estimated variables showed further improvement. However, the model that includes observed variables, estimated variables, and qualitative factors considering shippers' heterogeneity is the best. It was found that the mode selection behaviour of different latent classes of shippers is distinct. A mode shift from road to rail could be achieved by lowering transportation costs and increasing speed, reliability, and safety for fish transport. Expanding roll on-roll off facilities, dedicated freight corridors, parcel trains, refrigerated containers, and piecemeal service by rail promote a mode shift from road to rail and reduce energy usage.

Opis:
The public transport service is highly essential to meet the demand due to a rapidly growing population and mobility. Thus providing public service and improve its service becomes an urgent need in recent years. In Iraq, the Bus system represents the backbone in public transportation, which is based mainly on highway infrastructure. To meet the growing mobility needs, enhancing public service provided only by bus routes is essential. Measuring bus route performance represents one of the crucial transit research topics in the last recent years. The current study tries to investigate the urban public route's efficiency utilizing the "data envelopment analysis (DEA)" technique. To analyze route performance, DEA is using, and performance measures include route design, cost, service, operation, and comfort efficiency are selected and calculated for different routes. Efficiency and effectiveness are the output of this process. Bus company owners can also use the results of this study to improve their services, attract new customers, and better manage their resources.

Opis:
Public transportation plays a significant role in urban areas, transporting a large percentage of people. There is no existing study dealing with the balance between transportation demand and supply in Baghdad city; thus, there is a need to assess service equity before implementing any major services. The aim of the present research is to study the equity of transit need. The methodology uses geographic information systems (GISs) and spatial multi-criteria analysis to determine equity. Nine criteria were used in this study (land use, population density, commercial activities, medical locations, bus stops walkability, educational activities, bus terminal, and income) to determine a transit need map. Expert opinion surveys are conducted to determine pairwise comparisons between these criteria to estimate the weight of each criterion. Spatial analysis in ArcGIS 10.8 is utilized to apply methodology. The transit need map is obtained, and the need for transit service is represented by a value for each cell. In addition, the map output is important to public transit planning, as it maximizes the optimal transit route selection depending on the transit need. The output of this study (a transit need map) represents a powerful tool for the decision-makers to prioritize transportation programs and ranking alternatives. Gap analysis is used to measure equity between various zones. The results show that the transit supply provides higher service coverages in the Central Business District (CBD) and decreases as the distance to CBD increases.

The paper discusses the issues related to the measurement of the operating parameters of a conventional engine and the parameters of a conventional bus in motion. The measurements were performed under actual traffic conditions of a city bus in Poznań. It is noteworthy that onroad tests under actual operating conditions (PEMS) are one of the main trends of the development of the testing methodology and are gradually gaining in importance. Specific conditions were selected to ensure the highest possible reflection of the actual conditions: the traffic similar to the traffic typical of a regular bus route (average traffic on Poznań routes). The tests were conducted for two days (Friday and Saturday), characteristic of very high and very low number of transported people respectively as well as high and medium traffic congestion. During the tests the engine and the driving parameters were recorded continuously as sent from the diagnostic system of the vehicle and the GPS. The PEMS test method (portable emissions measurement system) presented in the article can be used in the measurement of exhaust emissions in rail vehicles with combustion engines.
W artykule omówiono zagadnienia związane z pomiarem wskaźników pracy silnika oraz parametrów konwencjonalnego autobusu w ruchu. Pomiary wykonano w rzeczywistych warunkach ruchu autobusu miejskiego w Poznaniu. Warto zauważyć, że badania drogowe w rzeczywistych warunkach eksploatacyjnych PEMS (Portable Emissions Monitoring System) są jednym z głównych trendów rozwoju metodologii badań i stopniowo zyskują na znaczeniu. Specyficzne warunki zostały dobrane tak, aby jak najlepiej odzwierciedlić stan faktyczny: ruch zbliżony do ruchu typowego dla zwykłej linii autobusowej (przeciętny ruch na trasach poznańskich). Testy były prowadzone przez dwa dni (piątek i sobotę), charakteryzujące się odpowiednio bardzo dużą i bardzo małą liczbą przewożonych osób oraz dużym i średnim natężeniem ruchu. W trakcie testów silnik i parametry jazdy rejestrowane były w sposób ciągły przesyłane z systemu diagnostycznego pojazdu i GPS. Przedstawiona w artykule metoda badawcza PEMS (badania emisji spalin w warunkach rzeczywistych) może zostać wykorzystana w pomiarze emisji spalin także w pojazdach szynowych o napędzie spalinowym.

The object of the paper is to investigate the strenght of a separated subsystem of a wagon for transport of trucks semitrailers. The wagon designed in the Department of Mechanics and Applied Computer Science, Military University of Technology, allows easy and independent loading, transport and unloading without any special equipment or additional platform infrastructure. It is possible to utilize it for transport of various vehicles types such as tractors, cars, semitrailers, containers, heavy equipment. The tests presented in the paper concern a wagon separated construction element – a side lock. It is a key subsystem of the platform allowing transfer of its loads generated in the transport position (a wagon ready to go) to the form of longitudinal forces operating in the sides of the structure. The locks are simultaneously the most strained parts of the wagon. There were carried out the numerical analyses and experimental studies of a single lock were carried out. Owing to the application of Aramis non-contact optical system of strains measurement, the lock deformations as well as the areas of the minimum and maximum main deformations were defined.

Opis:
A properly functioning public transport is one of the most important components of urban mobility for the population. Due to spatial inhomogeneity and overall socio-economic differences within a city, there are often considerable disproportions in the quality of transport services within its districts. Also, the city of Krakow is no exception in this case. For a comparison of public transport accessibility in 18 Krakow districts, 7 major quantitative and 5 minor indicators were created. These indicators include the most important characteristics of transport services such as accessibility, frequency, connectivity of connections, and ratios of tram public transport subsystem. The resulting values give a fairly comprehensive picture of the quality of the transport services. Overall higher values for most indicators occur in the central districts of the city. However, due to the complexity of the observed characteristics, it is possible to discover significant differences in the structure of individual indicators. Peripheral districts reach higher amplitudes, which means that in some aspect they have even better transport services than the city center. Yet, at the same time, we also find opposite extremes here, highly below-average values for most other indicators. A detailed analysis of the results provides a unique perspective on the disparities among districts. It can also serve for specific identification of strengths and weaknesses of transport services and its possible optimization.

Opis:
Nowadays, many residential buildings are built in areas close to railway and tram lines. Therefore, there is a necessity to find a method that allows taking into account in the process of building design influences of the vibration caused by passing trains and trams. This article presents analysis of propagation of vibration wave excited by the movement of trams in the soil on which is planned to build multi-storey residential building. To determine the amplitude of vibration the Finite Element Method (FEM) model was used. The FEM model which was used during the analysis takes into account variable heterogeneous mechanical properties of the soil. The analysis uses the results of measurements of vibration acceleration amplitudes done by employees of the Department of Robotics and Mechatronics AGH during the works on government research project 4875/B/TO2/2010/38 and the results of drilling carried out to identify the composition of the soil at the planned place of foundation building. The developed method allows determining the wave vibration in the ground without necessity to perform complex measurements of soil vibration. The proposed method can be successfully applied in the preparation of project documentation for public buildings and reduces the costs of preliminary analysis of the influence of the traffic on the dynamic properties of the newly designed facility.

Opis:
The article analyses the trends in the growth of electric vehicles (EVs) in Poland compared to the EU. Verification of the assumed objective required the application of research methods such as analysis of domestic and foreign literature, analysis of statistical data, and statistical inference. This article commences a series of publications on sustainable transport management and electromobility in Poland and selected European countries. The number of electric vehicles (BEV and PHEV) is still increasing in Europe, including Poland. In 2010, there were 591 registered EVs only which was only 0.005% of the whole number of cars registered in Europe. For the first time, the share of EVs exceeded 1% in 2015 (130,900 electric vehicles), and in 2020 more than 10% of EVs were in Europe (in 2021, 17.8%). The largest share of EVs in the total number of cars was recorded in 2021 in Norway (86%), in Iceland (64%), and in Sweden (46%). At the same time, the countries with the highest number of EVs include Germany (more than 2.5 million), France (1.7 m.), and Italy (1.4 m.).
Artykuł ma na celu analizę trendów w rozwoju pojazdów elektrycznych (EV) w Polsce na tle Europy. Weryfikacja założonego celu wymagała zastosowania metod badawczych, tj. analizy literatury krajowej i zagranicznej, analizy danych statystycznych oraz wnioskowania statystycznego. Niniejszy artykuł rozpoczyna cykl publikacji poświęconych zrównoważonemu zarządzaniu transportem i elektromobilności w Polsce i wybranych krajach Europy. Liczba pojazdów elektrycznych (BEV i PHEV) wciąż rośnie w Europie, w tym w Polsce. W 2010 roku zarejestrowano tylko 591 pojazdów elektrycznych, co stanowiło zaledwie 0,005% ogólnej liczby samochodów zarejestrowanych w Europie. Po raz pierwszy udział EV przekroczył 1% w 2015 roku (130,9 tys. pojazdów elektrycznych), a w 2020 roku w Europie było już ponad 10% EV (w 2021 roku było to 17,8%). Największy udział EV w ogólnej liczbie samochodów odnotowano w 2021 roku w Norwegii (86%), na Islandii (64%) oraz w Szwecji (46%). Jednocześnie wśród krajów o największej liczbie EV są Niemcy (ponad 2,5 mln), Francja (1,7 mln) i Włochy (1,4 mln).

Opis:
Transportation, representing 6% of GDP, plays vital role in social and economic development of the Republic of Belarus. The purpose of this article is to present the geographic analysis of current spatial structure of the road transportation in Belarus in 2000-2014. The choice of transport mode for the article was influenced by several factors, such as historic development, network coverage, transformational changes in productivity, rapid increase in car ownership numbers, emergence of logistic centers and intelligent transportation systems. The article reviews the range of topics, including morphology of the major roads network, logistic centers spatial distribution and regional features of passenger and cargo productivity, discusses current transformational changes within the road transportation sector in Belarus. The key findings indicate that current changes in spatial structure of the road transportation in Belarus have uneven nature, shaped by social, economic, political and geopolitical external and internal factors and are a subject of interest for both transportation researchers and practitioners.
