The demand of transport grows along with road traffic. Congestion costs 1% of the GDP of European Union (European Union 2014) and also causes significant emissions of carbon dioxide and other pollutants. This problem could be solved by transfering a part of passengers from private modes of transport to the public transport. But the essential condition is a sustainable development which means the accessibility on equal terms. Therefore, attention to the focus group – people with movement impairements, is neccessary. Since even under ideal conditions some of those people will not be able to use the ordinary public transport services, a special transportation service, called paratransit, should be offered. In this paper the parameters of paratransit as well as their variations are analyzed. Also the wider application possibilities are considered. The aspects of integration of paratransit into the existing system, pottential barriers for the integration and conditions for the integration are highlighted. The main purpose of this paper is to formulate the scenarios for the integration of paratransit into the existing public transport system based on the analysis of the scientific literature and the best practices, which could be used to form a policy of improving the accessibility of the public transport for people with movement impairments. Transporto paklausa nuolat auga, o kartu su ja ir kelių eismo intensyvumas. Spūstys Europoje kasmet sudaro apie 1 % jos BVP (Europos Sąjunga 2014), dėl jų išmetama daug anglies dioksido ir kitų nepageidaujamų teršalų. Ši problema miestuose gali būti sprendžiama perkėlus dalį keleivių iš privataus į viešąjį transportą. Tačiau labai svarbu, kad vykdomi projektai atitiktų tvarios plėtros principus, pagal kuriuos numatomas viešojo transporto prieinamumas lygiomis teisėmis. Todėl būtinas dėmesys tikslinei žmonių grupei – žmonėms, turintiems judėjimo apribojimų. Kadangi dalis tų žmonių netgi esant idealioms sąlygoms negalės naudotis tradiciniu viešuoju transportu, jiems yra būtina specialioji transporto paslauga, vadinama paratransportu. Šiame straipsnyje yra išskiriami paratransporto paslaugos parametrai, jų variacijos. Taip pat analizuojamos platesnės šios paslaugos pritaikomumo galimybės. Išskiriami transportinės paslaugos integravimo į esamą viešojo transporto sistemą aspektai bei potencialūs barjerai ir sąlygos paratransporto paslaugai įdiegti. Šio straipsnio tikslas – remiantis mokslinės literatūros ir gerosios patirties analize suformuluoti paratransporto įdiegimo į veikiančią viešojo transporto sistemą scenarijus, kurie gali būti taikomi formuojant viešojo transporto prieinamumo žmonėms, turintiems judėjimo apribojimų, tobulinimo politiką.

<zakljucak> Transport kriticno obolelih i povredjenih je klinicka situacija ciji su potencijalni rizici od komplikacija i slozenost veoma potcenjeni. Da bi se smanjio rizik od eventualnih komplikacija, oprema mora biti standardizovana (monitor za kardiovaskularnu i respiratornu funkciju defibrilator, transportni ventilator), a tim za transport uvezban. Mora postojati inter- i intrahospitalna koordinacija da bi se intenzivna terapija kriticno p/o mogla sprovoditi tokom transporta kao da je bolesnik u jedinici intenzivne terapije. Ovaj savremeni pristup transportu kriticno p/o poznat je kao portabilna intenzivna terapija (3).

Texto completoResumen
The public transit accessibility has become an important attribute of social and economic activity of contemporary society. The shift to the sustainable paradigm of the current cities’ development has made public transport the basic mean for population travels execution. The spatial character of the travels in the megapolises supposes its implementation with the transfers. This may result in the travel time increase if the transport hubs are designed or located inefficiently. In some cases, the transport hub locations do not reflect the current demand for public transport services and require the fulfilment of the infrastructure measures. The paper presents the Hub Location Problem (HLP) solving in the case of rapid transit and trolleybus lines interaction. It has been proposed the combined criterion for the HLP solving based on the two-dimensional coordinate system with the estimation of passenger walk turnover. The simulation procedure to estimate the transport hub relocation has been made in the PTV VISUM software in the case of the Industrial District of Kharkiv City (Ukraine). The results of the economic effect available from the transport hub rational location have been estimated.

Texto completoResumen
A new approach for spatial modelling of transport mode choice is presented in the paper. The approach tackles the problem by considering the trade-off between subjective and objective factors. To obtain mode Preference Rates (PRs) based on subjective factors, the Analytic Hierarchy Process (AHP) method is applied. The objective factors are expressed with the journey time from any point in the map to destination according to the available transport mode choice on the specific connection. The results are presented as PRs of individual transport modes. The model is validated on the conducted the survey, with students of Vienna University of Economics and Business (WU) as a target audience. Members of different target groups (age, national, employment) decide differently regarding the transport choice, so it is better to analyse them separately. The presented model can be used for the city transport planning in any urban area. It can help promote the sustainable modes of transport in the areas that are less adjusted in sustainable manner.

Jednostki i instytucje wojskowe realizują zadania szkoleniowe i operacyjne poza miejscem stałej dyslokacji. Zachodzi zatem konieczność przemieszczenia sił i środków na poligon czy też miejsce operacyjnego wykorzystania. Biorąc pod uwagę parametry i ilość sprzętu wojskowego zasadne jest korzystanie w przewozach wojskowych z możliwości transportu kolejowego. Mając na względzie konieczność zaspokojenia potrzeb gospodarki narodowej, jednostki i instytucje wojskowe chcąc korzystać z możliwości przewozowych transportu kolejowego zobowiązane są przestrzegać określonych procedur. Ogół spraw organizacyjnych na czas pokoju jest uregulowany odpowiednimi dokumentami normatywnymi. Jednocześnie jednostki i instytucje wojskowe są poddawane cyklicznemu szkoleniu, co stwarza przesłanki poprawnego korzystania z transportu kolejowego w przewozach wojskowych.

W artykule przedstawiono wymagania jakie muszą zostać spełnione przez jednostkę ładunkową przystosowaną do transportu bimodalnego (naczepę samochodową do przewozu paliw płynnych przystosowaną do transportu zarówno szynowego jak i drogowego). Przedstawione w artykule wymagania są oparte na obowiązujących przepisach drogowych (ADR) oraz kolejowych (RID). Obecnie kręgosłupem sieci transportu paliw w Polsce jest transport rurociągowy uzupełniony o transport kolejowy. Wykorzystanie typowego transportu kolejowego w postaci wagonów cystern powoduje konieczność przeładunku paliw do magazynu, a w ostatniej fazie do cystern drogowych. Transport bimodalny łącząc w sobie cechy transportu drogowego i szynowego rozwiązuje problem przeładunku. Bardzo dobrze rozwinięta w Polsce sieć dróg spowodowała rozwój sektora dystrybucji paliw za pomocą transportu drogowego. W związku z tym liczba przewoz ów paliw koleją zmniejszyła się pomimo bardzo dobrze rozwiniętej infrastruktury kolejowej na terenie kraju. W kontekście ekonomicznym i ekologicznym bardziej opłacalny jest transport szynowy, dlatego też powinno się dążyć do wzmocnienia jego pozycji na rynku przewozów. Naturalnym pytaniem jest, czy można połączyć transport drogowy i kolejowy dla osiągnięcia jak najlepszych wyników ekonomicznych? Odpowiedzią na nie jest transport bimodalny. W artykule zostaną przedstawione możliwości transportu paliw jego pomocą, zarówno jeśli chodzi o aspekt techniczny jak i przepisy z nim związane.

With the acceleration of globalization processes and increased international cooperation, freight transport routes are expanding, which requires new solutions for the most efficient use of various modes of transport. One of the most important factors that may improve the efficiency of the interoperability of different transport modes is information exchange allowing to plan transport flows in advance, exploiting benefits of the maritime and rail transport and minimizing its disadvantages. Precise information allows to find the most efficient mode of transport for the freight transportation chain. Precise information is necessary for effective management of information flows to ensure interoperability between the transport modes. This article analyses the specificity of railway and maritime transport modes, hence research questionnaire of Lithuanian transport companies is performed to present the results to show the most significant elements of railway and maritime transport interoperability. The completed expert evaluation enabled to prioritize the sequence of elements to ensure the efficient interoperability between rail and maritime transport.

Background: A skilled transport team is an essential requirement for safe and effective neonatal transport. The transport team of this level III NICU in Chennai performs a considerable number of transports every year and a need was felt to study the indications, complications and outcomes of transport.Methods: Prospective Descriptive study of neonatal transports conducted 18 months Patients were divided into 2 main groups based on transport Duration: Short (≤1hr) and Long (>1hr) transport groups. TRIPS (Transport risk index of physiologic stability) score, a risk- weighted validated neonatal transport was used as a practical system for assessing infant transport careResults: During the study period 210 transports were performed from 12 cities and towns. 60% transports were of short duration. Respiratory causes were the most common indications (43.8%) followed by CNS causes (19.5%). 44.3%(93) patients required ventilation during the transport process. Overall, there was improvement in mean TRIPS 2 score compared to TRIPS 1 in all groups of patients (Short, Prolonged, Survivors and Non-survivors). Total mortality of transported group was 31 patients (14.8%). (Including 02 patients who died enroute). There were non-significant differences in 7 day mortality (7.6% vs 8.4%) and total mortality (13.9% vs 13.4%) between the groups. Complications that occurred during transport included hyperglycemia, prolonged CFT, hypothermia, accidental extubation enroute, hypoglycemia, hyperthermia, Hypotension, and persistent Hypoxia.Conclusions: It appears, that overall, duration of transport does not adversely affect outcome. Transport Team should be able to intubate and ventilate the baby and diagnose and manage complications like hypothermia, shock and hypoglycemia at referring hospital and enroute.

Due to an increase in demand for energy and the mobility of the human population as well as in order to keep sustainable development, there is a major need to utilize alternative energy sources. The use of biogases as a source of renewable energy could provide an effective and alternative way to fulfil a remarkable part of this demand for energy. As biogases have high inert content, their heating value is low. The energetic utilization of these low heating value renewable gaseous fuels is not fully worked out yet because their combustion characteristics significantly differ from the liquid fuels that are used nowadays in transportation, and in this way, they are not usable or their utilization is limited in devices with conventional equipment. Thus, theoretical and experimental analysis was made to investigate the usability of biogases.

Texto completoResumen
Despite all the measures already taken and those still underway, pollution remains a major global problem, as the transport sector is the one where emissions are expected to increase in the coming years. Companies and policy makers are under increasing pressure to reduce the impact of their logistics activities in order to make transportation more environmentally friendly. One of the solutions to reduce emissions from intermodal transport is to choose the “right” mode of transport for each step in the transport chain. Such a measure increases the complexity of the transport chain and places an additional burden on transport companies in planning and organising transport for the entire transport chain. Additional difficulties arise from the fragmentation of information on emissions emitted for a single transport link and the lack of a unified approach to measuring and estimating transport chain emissions. As a result, this work finds that there is a lack of knowledge among users about the environmental impacts of transportation, despite the desire to contribute to greener transportation by paying more for a product or transportation service. The current research fills the gap in stakeholders’ understanding of the negative environmental impacts for individual transportation and for the entire transport chain. In addition, the study reveals a need for a systematically regulated and adapted way of informing users of intermodal transport chains due to the lack of transparency and comparison between different intermodal transport chains. To successfully address the challenges, the study proposes a 2-pillar approach. The 1st pillar approach focuses on designing a set of necessary measures (combination of top-down and bottom-up approach) for the transition to a low-carbon transport chain, while the 2nd pillar mainly focuses on mapping the level of green transport for easy comparison of similar products or services. The results of the research study show that the combination of numerical data with symbolic data is best suited to provide information on the level of green transport.

Currently, many logistics operators operate in both domestic and foreign markets using various forms of transport organization. Choosing a corresponding technology and appropriate form of transport has an influence not only delivery time and costs, but also has an impact on the environment as a whole. There is a plethora of public research available in global literature discussing various ways of exploiting transport. On the other hand, there is a lack of complex studies detailing carbon emissions coming from transport activity. Specifically, where a theory of organic fuel combustion in the form of a chemical reaction with oxygen is considered. To fill this gap, we offer an innovative Emission Model of Industrial Sources (EMIS) method. This method makes it possible to determine the amount of CO2 emitted into the atmosphere during various transport methods. It also enables us to estimate, in terms of CO2 output, a threshold where transport of containers via combined mode becomes more favourable for the environment, than road transport. We ran a simulation of our algorithm to create boundary conditions. This let us prepare a regression function of CO2 emission, for intermodal and road transport as a function of various transport distances. The simulation results suggest that our approach may be used by supervisory institutions, which are responsible further developing and utilizing combined transport.

The appearance of the COVID-19 virus has caused great changes in all spheres of life. Probably the most visible change is the cities’ lockdown, with the suspension of traffic and transport systems. The capital of the Serbia – Belgrade also went through a complete lockdown, which lasted for almost 2 months (53 days). In that period, nearly all activities were reduced, producing significant losses for the whole economic development, healthcare, food supply chain, transport sector and most importantly public transport system. The behaviour of users in such situations can greatly influence the change in the share of certain modes of transport in the overall modal share. The aim of this article is to examine the influence of the COVID-19 pandemic on the transport mode choice for different trip purposes, as well as the examination of different impact factors, such as gender, age, education level, employment status, income, transport mode used before the pandemic, and average distance travelled, on the change of mode of transport. Data of 1143 users were analysed through a survey, for the area of the city of Belgrade, using the McNemar–Bowker test and binary logistic regression. The results showed that pandemic had a significant impact on the transport mode change for all trip purposes. The key factors influencing the change in the mode of transport are factors related to gender, level of education, income, the type of transport used before the pandemic and the average distance travelled. It is also interesting to note that the results showed a significant number of transfers to individual modes of transport, as well as micromobility vehicles and walking. Therefore, this article provides the necessary help in understanding the transport system user’s behaviour, which can facilitate the choice of adequate measures, modes and activities for decision-makers in these specific situations.

The paper examines the problem of the productive functioning of an urban passenger transport system, which has a modular structure for the generation and exploitation of the urban transport services. The research objects consist of conventional, scalable and innovative contactless transaction models of an urban transport services in the case study of the Transport Organization (TO) – Joint Stock Company for Passenger Railway Transport “Serbia Trains” (Srbija Voz a.d.). The urban transport service is defined by invoking users, user expectations and requirements, the input data provided by users to a transport provider, the mechanisms for access and delivery of the service, the resources and roles responsible for delivery, security requirements and other parameters. The communication platform for modeling urban transport services in different transaction contexts is defined by the utilitarian framework with 6W dimensions with situational mapping of the 6 Communication Dynamics Factors (6CDF). The technology-process restructuring was achieved with the scalable In-formation Technology (IT) model by implementing the elements of electronic business in the key activities of the supply of the train tickets. Using the results of the performed research, in the paper has been developed an innovative, non-contact ICT model of urban transport services on the platform for integrating the Internet service into the process-technology and behavioral-context structures.

There are many concepts in the transport and logistics business: transport, logistics, transportation, forwarding, etc. There are also a number of different study programs and disciplines such as: transport economics, transport logistics, logistics management, etc. All of these titles are often related to the content of the plan, planning, organization, management and control of the movement of human, material, informational and financial flows. However, in practice, they are often correlated and misused. Therefore, it is an important task to properly define these concepts. This article, based on various scientific literature, deals with the concept of transport logistics in various disciplines and fields of research. The results of this analysis made it possible to identify that there is no unified logistic term. Therefore, a qualitative study was also used. The purpose of this study is to identify the concept of transport/logistics companies in the Baltic States as the concept is treated in business. The results of the research have shown that the concept of transport logistics is also understood differently. Therefore, the purpose of this article is to formulate the definition of transport logistics on the basis of the results of the scientific literature analysis and qualitative research.

This paper focuses on the development of a taxonomy framework for new and emerging technologies and trends in the transport sector. This framework is proposed towards the assessment and monitoring of the acceptance, impact and diffusion of technologies and trends, together with a scoring system and a front–end visualisation of the outcomes. In this context, an overview of the transport technology hype over the last years and the establishment of future transport technologies and trends is provided. Issues arising from different constraints, including technological and technical, are taken into account, also considering the transport sector’s interconnection with other sectors and potentially related bottlenecks and drawbacks. The paper outcome is a methodological framework for the creation of different taxonomies for new and emerging transport technologies and trends, achieved through the quantitative assessment of the attractiveness and competitiveness, in terms of diffusion potential, of emerging transport technologies and trends, by associating explicit indices to the various elements of the taxonomies. The proposed taxonomy, assessment and monitoring framework supports innovation management through the identification and evaluation of new and emerging technologies and trends in the field of transport at various levels, thus providing insights to the sector’s stakeholders, while backing the current transport systems’ transformation through technological advances

AbstractFor the first time, the temperature transport of the Agulhas Current is quantified in a time series. Over a 25-month mooring deployment at 34°S, seven tall moorings were instrumented to measure current velocity, temperature, and salinity. Current- and pressure-recording inverted echosounders were used to extend geostrophic velocity, temperature, and salinity records to 300 km offshore. In the mean, the current transports 3.8 PW of heat southward relative to 0°C: −76 Sv (1 Sv ≡ 106 m3 s−1) at a transport-weighted temperature of 12.3°C. A 0.9-PW standard deviation in temperature transport is due to variability in both volume transport and the temperature field. Meandering of the current core dominates variability in the temperature field by warming temperatures offshore and cooling temperatures near the coast. However, meandering has a limited impact on the temperature transport, which varies more closely with a deepening and broadening of the current associated with an inshore isotherm shoaling and an offshore isotherm deepening. Stronger southward temperature transports correspond to a deeper current transporting more volume, yet at a cooler transport-weighted temperature. Seasonality is not observed in the temperature transport time series, possibly because of the offsetting effects of cooler temperatures during times of seasonally stronger volume transports. Although volume transport and temperature transport are highly correlated, the large variability in transport-weighted temperature means that using volume transport alone to infer temperature transport results in an error that could be as large as 24% of the southern Indian Ocean heat transport.

Texto completoResumen
In this paper methods, criteria and models of safety assessment of multimodal transportation systems are investigated. Today, new types of transportation systems are formed – multimodal transportation systems, which may be defined as the result of the synthesis of several transport systems, where different modes of transport are effectively interact. The need for such systems was formed due to the peculiarities of each mode of transport, its technological and technical characteristics, which restrain the ability to compete and promote transport interaction. In this context, the problem of transport safety assess of multimodal freight transportations becomes highly important. An analysis of modern scientific researches on topic of transport safety is conducted. Unfortunately, the considered approaches to transport safety have a set of disadvantages if the complex systems are considered in form of, for example, combined, multimodal or intermodal transportations: the problem of local optimum; the problem of safety management in case of transport company is not the actual infrastructure owner; the problem of unifying estimates for several modes of transport, and so on. The system’s safety depends on its integrity and sustainable development, which is directly dependent on the objective conditions of its formation, development and operation. At the same time, the state of safety is directly dependent on subjective factors, the purpose of which is to ensure security, i.e., to preserve the integrity and maintain sustainable development and optimal functioning of the system. Thus, there is a conditional field of protection of transport system objects, which provides counteraction to a set of existing or perceived threats. In this context, modelling the transport safety assessment of multimodal freight is relevant and requires appropriate scientific developments. In the research, methods of mathematical modelling of transport systems were used in order to develop methodological approach that could be potentially used in improving the multimodal freight transportation safety. A methodical approach to safety assessment on the example of multimodal transportation, which takes into account the drawbacks of existing studies, is proposed. The practical application of developed model was demonstrated on the existing system of multimodal transportation. The developed safety assessment method may be potentially used both to assess the transportation route safety level and as key factor in optimal transportation route designing.

This study aimed to characterize the response of transport-naïve dogs to one and two-hour road transports based on cortisol in saliva and blood plasma, heart rate, heart rate variability (HRV), neutrophil to lymphocyte (N/L) ratio and behavior. Two persons familiar to the dogs were present during transports and control experiments. We hypothesized that transport elicits a stress response, which decreases with repeated transports. Beagle dogs were allocated to three groups (n = 6 each). Group 1 served as control in the stable in week 1 and was transported for one hour in weeks 2, 3 and 4. Groups 2 and 3 served as controls in a non-moving vehicle and in the stable, respectively, in week 2. All three groups were transported for two hours in week 6. Cortisol concentration increased during transports (p < 0.001), and this increase remained constant with repeated transports. Cortisol release during two-hour transports was not affected by transport experience. Cortisol concentration increased twofold in plasma and eightfold in saliva, indicating an increase in free cortisol. The N/L ratio increased during transport (p < 0.05). Heart rate increased at the beginning of transport while HRV decreased (p < 0.001). Heart rate and HRV neither differed among weeks nor between animals with different transport experience. During transports, but also in the stationary vehicle, dogs were mostly sitting, and time spent standing decreased during experiments (p < 0.001). Licking the mouth was the most frequent behavior during transports but not in the stationary vehicle (p < 0.01). In conclusion, a transport-induced stress response was evident in dogs. There was no habituation with repeated transports, and transported dogs may suffer from motion sickness.

The East-West Transport Corridor (EWTC) in the Southern part of the Baltic Sea Region (BSR) has been chosen as a practical area for implementation of a novel transportation concept called synchromodality. The main expectations in developing synchromodal transport system are related to the improvement of the transport service level, modal shift and capacities utilization of transport hubs along this corridor. However, in the absence of identification of major factors influencing synchromodal system it is difficult to evaluate a potential benefit of implementation of this new transport concept. Our main goal in this paper was, on the basis of a review and using a specific questionnaire, to determine the main indicators impacting effectiveness of the synchromodal system. Compatibility of experts’ opinions was verified by using Multiple-Criteria Decision-Making (MCDM) method. The paper will be useful for transport and logistics companies interested in moving towards synchromodal transport, as well as for future researchers. In the course of the research – using the Average Rank Transformation Into Weight (ARTIW) and Analytic Hierarchy Process (AHP) methods – it was determined that the normalized subjective weights of the five main criteria impacting synchromodality distributed in the following order: service quality, efficiency, infrastructure sufficiency, technical properties of terminals and interaction of technologies. In accordance with the Kendall’s concordance coefficient and consistency ratio values, expert opinions are consistent, which enabled the rankings of expert group averages and the eigenvector to take as a result of the task solution. The outcomes of the research presented in the paper have shown that service quality (transport time, service and waiting time, handling time, working hours, reliability and flexibility) is the most important indicator (criterion) impacting synchromodality. At the same time it is a big challenge for transport researchers because it requires to design and apply a qualitatively new mathematical models facilitating an establishment of an optimal synchromodal network and services along chosen transport corridor.

Texto completoResumen
At the phase of 13-th five-year plan in China, natural gas will play an important role in energy revolution. With the growth of consumption, natural gas infrastructures will become hot spots of future investment and pipeline network construction will also usher in a period of rapid development. Therefore, it is of great theoretical and practical significance to study layout methods of transport pipeline network. This paper takes natural gas transport pipeline network as a research object, introduces dominance degree to analyse benefits of pipeline projects. Then, this paper proposes Dominance Degree Model (DDM) of transport pipeline projects based on Potential Model (PM) and Economic Potential Theory (EPT). According to DDM of gas transport pipeline projects, layout methods of pipeline network are put forward, which is simple and easy to obtain the overall optimal solution and ensure maximum comprehensive benefits. What’s more, construction sequences of gas transport pipeline projects can be also determined. Finally, the model is applied to a real case of natural gas transport pipeline projects in Zhejiang Province, China. The calculation results suggest that the model should deal with the transport pipeline network layout problem well, which have important implications for other potential pipeline networks not only in the Zhejiang Province but also throughout China and beyond.

Safe transport of dangerous goods by railway is an important challenge for both national and international freight transport. The transport of dangerous goods is one of the most demanding transportation technologies. The aim of this article is to assess the conditions for the transport of dangerous goods by railway and to define the main factors, which affect the transport of such goods by railway. Scientific literature was analysed, statistics were provided, and a qualitative survey was conducted. The factors of 3 groupas that have the greatest impact on the safe transport of dangerous goods by railway were studied and identified. The obtained results were processed using the Kendall’s rank correlation method, and the consistency of the expert opinions was clarified using the fit coefficient. Using the medium-distance transformation weights (Average Rank Transformation Into Weight – ARTIW) method, the main normalized subjective weighting factors that most influence the conditions of transport of dangerous goods for safe transport have been identified. The results of the study revealed that the main factors of Group I that have the greatest impact on the accident of dangerous goods by railway, are: complete preparation of the train, driver’s confidence in the safety systems of the locomotive and improper loading of cargo. The most important technical-technological factors of Group II, which have the greatest impact on the accident occurring in the transportation of dangerous goods by railway, are: technical condition of the locomotive, tightness of railway tanks (wagons) and marking of wagons carrying dangerous goods. Key organizational factors for Group III to consider before dangerous goods are transported by railway are: risks related to freight forwarding, identification of chemical properties of freight and driver qualification. The key factors in these three groups can be used to develop models to make the transport of dangerous goods by railway safer and more efficient.

The concepts "connection", "parallel transport" and "transport along paths" are axiomatically defined. In differentiable bundles, bijective mappings between the sets of connections, parallel transports and transports along paths satisfying some additional conditions are found; in particular, the equivalence between the concepts "connection" and "(axiomatically defined) parallel transport" is established. Some results, which are specific for topological and vector bundles, are presented.

AbstractIntroduction:Pediatric Emergency Air Transports (PEATs) at Massachusetts General Hospital, Boston, Massachusetts, were reviewed between November 1986 and December 1987. Severity of illness, complications, and outcome of PEATs were compared with ground transports. Factors associated with PEAT survival were identified.Methods:Severity of illness was measured using a modified Denver Patient Status Category (DPSC) method and the Therapeutic Intervention Scoring System (TISS). There were 35 PEATs (30 helicopter, five fixed-wing) and 96 ground transports.Results:Mean severity of illness for patients was greater in PEAT than for the ground transport (PEAT DPSC score=4.23±1.06 versus ground DPSC=3.57±0.89 [SD], p=.0005). The PEAT mortality was associated with a greater mean severity of illness (TISS survivors=19.1±11.4 versus non-survivors=44.3±9.5, p=.0001), but not with: the presence of an in-flight physician; transport delay; transport duration; age; sex; history of chronic illness; or intra-transport medical complication.Conclusions:Compared to ground transports, PEATs were used for higher risk patients.

OBJECTIVE: To investigate the rate of interhospital emergency transport for bronchiolitis and intensive care admission following the introduction of high flow nasal cannula and standardised paediatric observation and response charts. DESIGN: Retrospective cohort study. SETTING: A statewide paediatric intensive care transport service and its two referral paediatric intensive care units (PICUs) in Victoria, Australia. PARTICIPANTS: Children less than 2 years old emergently transported with bronchiolitis during two time periods: 2008–2012 and 2015–2019. MAIN OUTCOME MEASURES: Incidence rates of bronchiolitis transport episodes, PICU admissions and respiratory support. RESULTS: 802 children with bronchiolitis were transported during the study period, 233 in the first period (2008–2012) and 569 in the second period (2015–2019). The rate of interhospital transport for bronchiolitis increased from 32.9 to 71.8 per 100 000 children aged 0–2 years. The population-adjusted rate of PICU admission increased from 16.2 to 36.6 per 100 000 children aged 0–2 years. Metropolitan hospitals were the predominant referral source and this increased from 60.1% of transports to 78.6% (P < 0.001). In children admitted to a PICU, the administration of high flow nasal cannula during transport increased significantly from 1.7% to 75.9% (P < 0.001) and a concomitant reduction in continuous positive airway pressure and mechanical ventilation occurred (40–12.4% and 27–6.9% respectively; P < 0.001). The proportion of mechanical ventilation as well as PICU and hospital length of stay decreased over time. CONCLUSIONS: The population-adjusted rate of interhospital transport and admission to the PICU for bronchiolitis increased over time. This occurred despite a lower rate of non-invasive and invasive mechanical ventilation during transport and in the PICU.

Recently, there has been a transparent need to involve public in transport development decisions not only in the EU but also in other countries worldwide. Public involvement in decision-making, however, suffers from two critical issues: lack of expertise and lack of enthusiasm. This paper aims to overcome the first problem: how to amend passenger preferences related to public transport development with expert knowledge on transport systems. For this purpose, a new research methodology has been created which combines the well proven Analytic Hierarchy Process (AHP) and Interpretive Structural Modelling (ISM) methods in a novel way. ISM is used to reveal the non-hierarchical connections of the transport system elements and by this, AHP results are modified with the consideration of element interactions. The first stage of the three-stage-survey has been conducted in Yurihonjo (Japan), the second and third in an international workshop with the participation of experts. Results show that the original AHP scores – gained from passenger evaluations – are significantly modified by adding expert knowledge on factor interactions, thus new preference order is gained related to the importance of the development of public transport system elements. The introduced procedure can be applied for other public transport system improvement decision-making situations in which passenger involvement is required.

Sustainable development has turned into a daily concept by now. Similarly, sustainable transport also appears increasingly often, primarily in transport policy and strategic plans. However, it would be equally important if we could apply this aspect for certain activities such as haulage and forwarding that are a part of transport. Today, forwarders select an optimal alternative concerning only the criteria related to the economic effectiveness of the transport task. In many cases, shippers are not aware neither of the concept of sustainable transport nor of harmful effects they generate. Hence, although there is a concept of ‘freight integrator’, only very few are able to meet the requirements laid down for it. No widespread method has been developed yet to compare transportation options. A similar situation can be faced discussing a traditional, purely economic approach and a theoretical modern aspect that would be in accordance with the principles of sustainable transport. The model that was developed at the Department of Aircraft and Ships of Budapest University of Technology and Economics was designed specifically to compare various options in terms of sustainability. The indicators as the elements of decision-making criteria applied in the model were derived from the indicators used for assessing the transport sector but modified according to the requirements of the decisionmaking task for a freight integrator. Finally, such sustainable performance index of certain alternatives is determined by two fundamentally different aggregation methods as ‘fineness index’. This article presents the model structure and application using a concrete example.

The paper presents a procedure for modelling transport demand and analyses effects caused by changes in the characteristics of street network exploitation. Based on the effects of the measures predominantly connected with speed restrictions on characteristic sections, the Scenarios resulting in reduced congestion during peak hour and a decrease in harmful effects of traffic were selected. A rough effectivity analysis of transport vehicle kilometres travelled and travel time on the network was carried out. Transportation modeling is the most efficient way to analyze the effects of traffic solutions. Once established, transport model brings only benefits in future projects. Speed reduction strategy was easily simulated using the transportation modeling procedure. Other sustainable transport and mobility management strategies considering sustainable transportation could also be simulated.

This paper considers managerial approaches to increase efficiency of the urban transport system such as promotion and integration of sustainable modes of transport, development of public transport route network, renewing the existing vehicle fleet and shift to environmental friendly fuel types in the public transport system. To assess such kind of efficiency, it is proposed to take into account the economic viability of suggested solutions as well as their influence on social sphere, environmental friendliness and sustainability of the urban transport system. The city of Naberezhnye Chelny (Russia) was chosen for the case study, where the following measures were modelled: changes of bus route network and choice of an optimal fleet on routes depending on passenger flow by hours of day. In addition, the efficiency of these measures were assessed. To evaluate the sustainability of the proposed route network, the method of “radar map” was used, which shows both strengths and weaknesses of selected indicators. Together with this evaluation, analysis of risks in managing the urban bus transportation was carried out.

Forecasted/projected rise of impacts in modes of transportation has necessitated a new rethinking of the evaluation of total impact. While most researchers deal with defined parts (like environmental impact) of the total impact. The total impact calculation methodology includes: (1) analysis of all the impacts (environmental impact, safety and security, costs, cost benefits and sustainability), (2) evaluation on the transportation system level, (3) as their total value (including all the related sub-systems and elements, i.e. transport infrastructure, transport flow control), (4) generation of total impact index. Such an index might be called as transport total sustainability index. The paper defines the Total Impact Performance Index (TIPI) evaluating the total impact in the form of generalized (summarized) costs, specifies its calculation methodology, develops a simplified Excel based calculation methods. It aims to demonstrate the applicability of this methodology, which involves evaluation of impacts in more detailed forms, two parts calculation methods namely impact of road transport safety aspects and impact of the railway transport. Finally, some selected results of the applied new index calculation and developed methodology are introduced and analysed.

Effective planning and optimization of rail transport operations depends on effective and reliable forecasting of demand. The results of transport performance forecasts usually differ from measured values because the mathematical models used are inadequate. In response to this applicative need, we report the results of a study whose goal was to develop, on the basis of historical data, an effective mathematical model of rail passenger transport performance that would allow to make reliable forecasts of future demand for this service. Several models dedicated to this type of empirical data were proposed and selection criteria were established. The models used in the study are: the seasonal naive model, the Exponential Smoothing (ETS) model, the exponential smoothing state space model with Box–Cox transformation, ARMA errors, trigonometric trend and seasonal components (TBATS) model, and the AutoRegressive Integrated Moving Average (ARIMA) model. The proposed time series identification and forecasting methods are dedicated to the processing of time series data with trend and seasonality. Then, the best model was identified and its accuracy and effectiveness were assessed. It was noticed that investigated time series is characterized by strong seasonality and an upward trend. This information is important for planning a development strategy for rail passenger transport, because it shows that additional investments and engagement in the development of both transport infrastructure and superstructure are required to meet the existing demand. Finally, a forecast of transport performance in sequential periods of time was presented. Such forecast may significantly improve the system of scheduling train journeys and determining the level of demand for rolling stock depending on the season and the annual rise in passenger numbers, increasing the effectiveness of management of rail transport.

This paper presents a case study using Quality Function Deployment (QFD) method to identify urban public transport users’ needs and requests and to improve service quality in urban public passenger transport in Belgrade. In order to determine users’ satisfaction, a direct interview – survey a sample of 15000 of urban public passenger transport system users, according to the defined questionnaire has been performed. Results of these interviews are used as input in the first stage of QFD method. An overall unit of eight features and a total of 48 sub-features were defined, which describes all aspects of quality of system and services in urban public passenger transport. The results show that for maximizing effects of quality of service improvement and satisfying customers’ requirements, the public transport service providers and managers in Belgrade should focus primarily on the service reliability and vehicle elements. The two most important quality of service sub-features in urban public passenger transport system in Belgrade based on frequency of statements of users was regularity with 4896 (32.64%) and vehicle comfort (not crowded vehicles) with 3446 (22.97%) statements. Based on the service features analysis within the house of quality, it was defined that the biggest influence is generated through system functioning parameters (reliability): frequency with relative importance 22.0%, staff (drivers) with relative importance 14.0% and headway with relative importance 13.0%. Based on absolute importance the greatest importance should be assigned to vehicle frequency – rank 1, staff (drivers) – rank 2 and headway – rank 3.

This paper focuses on analysing the determinants of satisfaction (service quality, perceived value), as well as its possible influence on customer loyalty of freight forwarders to freight transport service providers (by road/maritime/air) in Spain. To this end, we propose a causal model tested using information from 205 freight forwarders collected through personal interviews. The model was estimated using the Partial Least Squares (PLS) approach. Moreover, the existence of differences in the perceptions on the analysed variables between transport modes is tested through ANOVA. Results show that service quality has an influence on customer satisfaction, both directly, as well as through perceived value. In turn, it is confirmed the relationship between satisfaction with the transportation company and customer loyalty. Furthermore, there are significant differences in quality dimensions and satisfaction between transport modes. This study confirms the importance of service quality and perceived value to promote the link between chain actors: freight forwarder and transport service provider. The main aim of this research is to go deeper into the study of satisfaction and loyalty of freight forwarders to freight transport service providers. Findings provide evidence about differences in the dimensionality of service quality between B2C and B2B settings and, even in the latter, differences between freight forwarding services and other industries are observed. The present paper is one of the few studies that obtains relevant information about several transport modes simultaneously and the findings reinforce the notion that perceptive processes in each of them are different.

Sustainable development is the most researchable sphere of many experts in urbanistics, architecture, transport, environment and economics in Lithuania. Every period of time has specific problems and solutions to solve them. The present days have increased the level of automobilization and growing traffic in cities has become the main task for sustainable development. State‐wide improvement and development of transport infrastructure relate to the level of assigned investments that depend on State transport policy and existing opportunities. Comparing to several EU member states, the procedures of evaluating data on transport infrastructure projects evolved in parallel with the EU‐financed projects. Therefore, it could be stated that this area is not falling behind. The analysis of evaluation methods in Lithuania and foreign countries showed that there were no standardized and united methods for evaluating projects on urban system infrastructure. During the last decade, investment projects in cooperation with the State were evaluated using complex analysis in Lithuania. Cost‐benefit analysis was and is still being used for evaluating the EU‐financed projects. Multicriteria analysis is often carried out in the EU and other countries to evaluate the financial feasibility of transport infrastructure and takes its first steps in Lithuania.

Intrahospital transports rely on effective transmission of information between medical staff and information systems to support Distributed Situation Awareness (DSA) on patient status and transport requirements. This study presents the preliminary results a simulation model combining discrete event simulation (DES) and agent-based modeling (ABM) to quantify SA distribution and transactions for intrahospital transportation. The simulation model captured the transport requests, transport processes, and knowledge distribution and transactions between (human or machine) agents for intrahospital transports. Specifically, this paper presents the simulation results for the successful patient transport from 17 hospital inpatient units to the radiology department for (1) transport times and (2) transport cancellations. One-way t-tests did not reveal any significant differences in average transport time and number of cancelations between outputs of 100 simulation replications and historical data for 18-month operation. These results indicate that the simulation model represents real-world operation that can subsequently be used to test potential intervention to improve DSA in patient flow.

One of the main objectives for a rail company is to minimize the size of rail freight car fleet in order to reduce operating costs. The problem of rail freight car fleet composition is aimed at determining an optimal structure and size of freight car fleet in order to respond to actual transport demand. A rail company must have capabilities to respond to actual transport demand in case it wants to increase the level of competitiveness on the transport market. Therefore, it is necessary that the structure and size of rail freight car fleet correspond to the structure and size of rail transport demand. In this paper, we developed a two‐level approach to determining an optimal rail freight car fleet composition. This approach has been tested for the case of the Public Enterprise ‘Serbian Railways’ and the obtained results show the potential for a practical application of the proposed approach.
