Transportation is a key logistics function, which determines the dynamic nature of material flows in logistics systems. At the same time, transportation is a source of uncertainty of logistics operations performance in the supply chain. Obviously, the development of a new approach for evaluation of the duration of delivery “Just-In-Time” (JIT) will improve the efficiency of supply chains in accordance with one of the major criteria, namely customer satisfaction. One of the basic approaches to make effective management decisions in transportation and other logistic operations is the JIT concept. In the majority of examined sources the JIT concept is described on the verbal level without any usage of calculation dependences. The paper is devoted to the formation of analytical and simulation models, which allow obtaining the probabilistic evaluation of the implementation of unimodal and multimodal international transportation JIT. The first model where the order of the operations implementation does not affect final result is formed on the basis of the probability theory: distribution laws composition, theorems of numerical characteristics of random variables, formula of complete probability. The second model accounts the impact of operations implementation order in transportation and their interconnection and is based on the simulation (the method of statistic experiments) and shown as a corresponding algorithm, which allows to consider different limitations (technical, organizational and so on). Considered analytical dependences give the possibility to obtain the necessary estimations of the transport operations implementation according to JIT: mean transportation time, delivery implementation probability by the set moment or the delivery time with the set probability. To carry out some comparative calculations and clarify the algorithm, two international routes have been chosen: the first one is a unimodal road transportation, the second one is a multimodal transportation (road and marine transport). All the data, which is necessary for calculation has been collected on the basis of official information (in particular, the data of tachograph, special questionnaires filled in by the drivers, the survey results of the managers). For unimodal transportations analytical dependences and modelling results give close results. For the combined multimodal transportations taking into account various limitations the preference must be given to the simulation. The modelled indexes take into consideration their intercommunication and definitely estimate the supply chains reliability, and this allows decreasing the uncertainty of the logistic system.

Abstract The increase of the utilization of public rail transportations is searched in directions for redistribution of the passenger travels between rail and bus transportation. The rail transport benefits by redistribution of the transportation flows on paths, predominantly supported by rails. The redistribution of the transportation is formalized by bi-level optimization problem. The upper level optimization estimates the maximal flow, which can be transported through a transportation network, supported both by bus and rail transports. The lower level optimization gives priority to the rail transport by decreasing the costs of flow distribution, using rail transport. This bi-level optimization problem was applied for the case of optimization of the rail exploitation in Bulgaria, defining priorities in transportation of the National transport scheme.

Full textAbstract:
Impact assessment, in general, includes the environmental safety and security considerations, and cost/cost-benefit analysis of the used sources. As usual, the impact is evaluated at two levels: (1) impact during operation (usage) related to a chosen operational unit (e.g., running distance [km], operational time [h] or calendar time [h]), (2) the life-cycle (project life-cycle) impact. The environmental impact is characterized by the chemical and noise emissions. Safety and security are estimated by risks. Costs are calculated based on the required financial support and caused losses. All these calculations are related to the individual vehicles or vehicles with average behaviours. The investigation of sustainability impact requires a wider evaluation and approach, for example, by also including production and recycling beside the operational aspects. This paper generalizes the impact analysis. At first, it considers all types of impacts including the direct (e.g., accidents) and indirect long-term effects (e.g., health problems caused by emissions). All the impacts are expressed as costs. The defined Sustainable Transportation Performance Index (STPI) is the Total Life-Cycle Cost (TLCC) related to the unit of transport work. As such, it combines the life-cycle emissions evaluation and transport costing methods. It contains the total operational and total impact costs. The proposed approach introduces three new specific features in the impact analysis: (1) the impact is evaluated on the transportation system level, (2) the impact is estimated as the total value (including all the related sub-systems and elements, like vehicles, transport infrastructure, transport flow control, etc.), (3) proposes a unique index to describe the total impact. The paper describes the general equations and the developed methodology for the estimation of the total impact and analyses its applicability. The preliminary results demonstrate the applicability of the defined index and its evaluation methodology. It also shows the limitations of traditional cost models. Further test results and wider application of the methodology will be provided in a series of follow up papers by the research team.

The paper is devoted to the analysis of maritime transport logistics. The authors analyze the issues of optimizing the work of organizations of all activities. The purpose of the work is to systematize and develop the theoretical and practical basis of maritime transport logistics. The purpose of sea transportation, types of cargo, directions of transportation, subjects of sea transportation, structure of the fleet are analyzed. The main types of sea transport vessels and main ports are provided. Features of sea logistics and names of the most known companies of sea logistics are presented. The introduction highlighted the work of domestic and foreign scientists on logistics. The study used methods of comparative analysis, synthesis, generalization, induction and deduction. As a result, maritime transport currently provides 4/5 of the world's cargo. Maritime logistics, ie the organization and provision of sea freight, is a special intermediary transport service that facilitates the process of delivery of goods from producer to consumer, regardless of the distance between them. Maritime logistics, ie the organization and provision of sea freight, is a special intermediary transport service that facilitates the process of delivery of goods from producer to consumer, regardless of the distance between them. The prerogative of maritime logistics is the transportation of goods by sea. This method of transportation is most suitable for the delivery of large over heavy loads over long distances. The organization of competent logistics of sea transportations is an important component of successful business. Transportation of products using ships has a number of advantages, due to which this type of delivery is one of the main, especially in the case of long-distance transportation.

The article is aimed at defining the key difference between multimodal and intermodal transportations, as well as studying the role of transport operators in the organization of multimodal transportations. In the course of the study, it was identified that both in the scientific field and in practice, mixed transportation is often understood as synonymous with the concept of «multimodal transportation», but it is determined that all integrated (multimodal, intermodal, combined) and separate (segment) transportations are part of mixed ones, which complement each other. It is noted that multimodal and intermodal transportations have a certain difference between themselves, which consists in the presence of the number of contracts and the responsibility borne by the transportation operator. It is proposed to take into account all the conditions that cause influence on the result of the decision on the implementation of multimodal transportation. In the study of theoretical and practical aspects it was possible to allocate the operators of multimodal transportation as follows: operators who operate with sea vessels; operators who do not operate with sea vessels, but may own other rolling stock, warehouses, etc.; forwarders who are not always multimodal operators and can be agents of some part of a transportation and cooperate with the main operator. Their special role in the organization of multimodal transportation is substantiated, taking into account all the factors and elements that must closely interact with each other in the delivery process. Prospects for further research in this direction are the construction of an algorithm for choosing a multimodal operator, taking into account various conditions.

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.

The shipments were absolutely necessary at all times, but still have polluted and damaged the environment. The technique of transport or the engineering of transport is the application of the principles of technology and scientific findings to the planning, design check, operation and plan management for any mode of transport, in order to ensure that the conditions of safety, efficiency, quick, comfortable and convenient, economic and environmentally compatible movement of persons and goods (transport). It is a sub-discipline for civil engineering. The importance of the transport engineering in the framework of the profession of civil engineering can be evaluated by the number of divisions of the ASCE (American Society of Civil Engineers), which are directly related to the transport. There are six such divisions (Aerospace; Air Transport, motorways, pipes, watercourses, port, of coastal and ocean and urban transport), which represents one third of the total 18 technical divisions of the ASCE (1987). Humanity is struggling between technological tests of deployment of new types of mild transport for the environment and the need to maintain still in the operation the machines already polluting products in large quantity, cheaper, more convenient economically, that customers have already been accustomed. Transport is at the heart of major cross-cutting issues that are inseparable from issues related to the development and sustainable management of the mobility of goods and people. The automotive sector must meet several challenges to reduce the emission of particulate and gaseous pollutants while limiting the increase in the cost of vehicles. The development of "clean" or "sustainable" vehicles requires the integration of innovative technologies to meet all these requirements. Those all problems need to be addressed by the discipline named Transportation (Transport) Engineering, in view of the constantly improving the quality of transport carried out.

Prominent influence of transportation costs on supply chain overall profit indicates the importance and emer-gence of transportation optimization models. Regarding this issue and in view of realistic situation consisting of non-de-terministic information, in this research optimizing inbound and outbound transportation costs of a multi echelon supply chain has been considered. To deal with uncertain time deliveries and pricing strategies adopted by different members of supply chain, in conjunction with unpredictable demand rate, fuzzy logic and specifically Trapezoidal Fuzzy Numbers (TrFNs) are included. After designing a fuzzy binary multi objective model based upon structural assumptions, the solving approach is proposed and the model is employed on Iranian steel supply network to illustrate the potential and advantages of our scheduled model. The bi-objective mixed integer fuzzy programming model presents and encompasses many realis-tic circumstances making the model applicable in network transportation cases.

Road transport represents one of the greatest areas of challenge for energy efficiency. A growing percentage of petrol usage is due to consumption in the transportation sector. However, in other sectors, petrol has been recently partially or totally substituted by other fuels. The need for worldwide action to achieve energy efficiency in the transportation sector has been recognized by the agencies of the United Nations and other international governmental and non‐governmental organizations. Transportation is one of the key factors for the growth and development of Malaysian economy. Currently, more than 80% of primary energy consumption based on fossil fuels and demand stays high and is supposed continually grow in the future. Even if technology developments eventually able to reduce specific consumption, world energy demand is likely to increase in line with its population. This sector also accounts for a substantial amount of air pollution in cities and contributes significantly to greenhouse gas emissions. This paper aims to analyze factors influencing the pattern and emission level of energy consumption in the transportation sector of Malaysia and extrapolates the total energy demand and vehicular emissions.

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.

Competitiveness indicators for transport services are changing under the influence of both intra-industry factors and the conditions of the transport market and macroeconomic conditions. At the same time, under the conditions of continuous improvement of quality and differentiation of transport services of the competing companies, the requirements put forward by freight owners to trucking companies change. The article proposes a new method of assessing the competitiveness of a motor transport company by the transport service quality indicators. The developed model allows to assess the competitiveness of the motor transport enterprise on the basis of the transport service quality indicators, taking into account both the importance of the individual factors of quality in the general system and their various changes. This model can be used to provide an indicative assessment of the quality of transportation in various segments of the freight market.

Abstract The increase of the rail public transportations is searched in directions for redistribution of the passenger travels between rail and bus transportation. The rail transport benefits by increasing it schedule for places where the transportation capacities on appropriate directions is not achieved. A mathematical model has been derived to assess the potential of the rail passenger transport to increase his capacity and efficiency. This potential has been evaluate in comparison with the competition of the bus transportation. A specific transportation route has been chosen from Sofia to Varna and the potential for increase of the rail transport has been evaluated. The mathematical model uses bi-level optimization problem, related to the evaluation of a maximal flow in a transportation network.

Sustainable development is a kind of development where the pace of technical development, the satiation of increasing supply and the raw materials and resources of the Earth are poised so that the rate of living and the opportunities of the future generations should not decline. For this reason, transportation systems must be developed and the effectiveness of transportation service must be increased while environmental pollution must be decreased or prevented. Vehicles are burning fuels inefficiently. There are two options of decreasing environmental impacts – one is to reduce fuel consumption while another is to do it in a more acceptable way increasing efficiency. There is justifiable demand put forward by the society to moderate environmental impacts caused by road transportation. This article deals with modelling the energetic utilisation of exhaust gas.

The passenger transportation practice, both in Russia and abroad, shows that this transportation give little profit or completely unprofitable with the exception of tourist transportation. Given the social significance of passenger transportation for the population of the vast territory of the Russian Federation, state authorities implement measures of the state support for various types of transport for these transportations, including reimbursement of expenses to transport enterprises from budgets of various levels. Obviously, the question which type of transport to subsidize and how much requires special attention. At the same time, passenger transportation subsidizing by inland waterways has been canceled since 2005, and decisions made in the constituent entities of the Russian Federation on subsidizing from regional and municipal budgets quite often do not compensate the expenses of shipping companies. The article proposes possible options, in fact, for the revival of socially significant passenger transportation by inland water transport in Russia and proposes an approach to determining the maximum amount of subsidies to cover the loss of socially significant passenger transportation. The authors of the article have shown due to what factors direct and indirect (non-transport) components of the effect can be obtained as a result of the implementation of their proposals in the practice of water passenger transport enterprises.

Considering the importance of maintaining network performance at desired levels under uncertainty, network reliability, as a new approach to assessing the performance of degradable urban transportation networks, has become increasingly developed in two recent decades. In this paper, a method for optimizing resource allocation to meet the required levels of transportation network reliability is proposed. The worked out method consists of two stages: at stage one, a method for computing the reliability of network connectivity based on the reliability of computing arc performance with an assumption that capacities are random variables for each arc is presented. These random variables are assumed to be conformed to especial probability density functions which can be modified through investing to improve the performance reliability of the arcs. At stage two, a mixed integer nonlinear programming model is developed to optimize resource allocation in the network. Numerical results are also provided in a simple network to demonstrate the capability of the employed method.

The research purpose is to build the lot cargoes automobile transportations in cities system model. The research object is the lot cargoes automobile transportations in cities process. As the analysis result of lot cargoes automobile transportations rational technology formation in the cities, such basic problem at the transportation process organization is allocated - it is irrational transportation routes. It leads to a large overall truck mileage, as well as low transportation speed, which is unacceptable in the current competition. During the literature sources analysis, the most popular existing transportation routing methods were considered, by means of which in research it is planned to carry out transport routes building in cities and it was found out that the routes developed by means of these methods have average links. As the existing criteria analysis result of lot cargoes automobile transportations rational technology formation in the cities the transportations cost is chosen as a criterion. After analyzing the all modeling methods advantages and disadvantages, taking into account the scientific literature recommendations, it was decided to use mathematical modeling due to its results versatility and accuracy.

Jakarta Special Capital Region is surrounded by a lot of infrastructures to support its citizen, unfortunately it is not enough to cope with the citizen’s growth. The scarcity of infrastructures are easily seen in a lot of sectors, including transportation sector where the numbers of mass transportation systems are not equal with the population numbers, the widening road numbers which also lack in comparison with the growth of vehicles, etc. These kind of problems make Jakarta Citizens preferring to use personal transportation rather than public transportation, which causing more serious problems such as the increasing in transportation costs, reducing the mobility of its citizens, and decreasing in population quality of life because of heavy traffic jam that happens on daily basis. To solve these problems we need to create a development concept that can comply with the mobility of the people and oriented in mass transportation which is called Transit Oriented Development (TOD).The reason why Dukuh Atas were chosen is because Dukuh Atas located in the heart of Jakarta City and also surrounded by business districts, it also becoming a central hub where many public transportations route are connected, such as Airport Train Railink, KRL Commuter Jabodetabek, Transjakarta, LRT, MRT.One strategic spot that will be developed as a transportation hub is located in Jl. Kendal, right at the front of KRL Sudirman station. The design of transportation hub as a Dukuh Atas TOD will be considering eco friendly concept, hopefully it will create a city development that can increasing the quality of the life of its citizen.

Passengers’ transportation by rail involving various interested groups, such as managers, service staff and passengers, is a complicated process. Decision‐making persons, organizing railway trips should take into account the interests, needs and possibilities of these particular groups. The solution to some problems associated with passengers’ transportation by rail depends on the experience and qualification of decision‐makers, people who are responsible for the effectiveness of this work. To increase the quality of railway trips, the interested parties, groups of people mentioned above, should coordinate their actions, cooperate with each other in solving the problems and exchange relevant information. Therefore, the increasing quality of passenger transportation is a complicated issue, requiring good professional skills based on knowledge, practical experience, high intellect and new ideas of all the people involved in this process. The current paper presents a diagram showing passenger's transportation quality with a number of criterion groups A, B, C, D matching the structure and numbers of the questions included in the questionnaires to survey respondents (passengers) and experts (service and administration staff of the train). What is more, the Analytic Hierarchy Process (AHP) methodology based on the pair wise comparison of criteria is used to determine their weights (significances) considering the data obtained from the respondents and experts of each of three categories. Only these questionnaires which have no contradictory estimates are used. Also, the calculation methods demonstrating the results of the survey are provided in this work. One more point such as the data elicited from the respondents who took part in the survey (i.e. passengers from the train running on the international route Vilnius‐Moscow) and experts (i.e. service staff of the already mentioned train and representatives of the administration staff from the Joint‐Stock Company ‘Lithuanian Railways’ (AB ,,Lietuvos geležinkeliai")) is analyzed. Finally, the conclusions for improving the quality for passenger transportation by Lithuanian railways are given.

International transport corridors play a leading role in shaping an integrated global transport services market.In this context, the objective of the paper was to study the current state of North–South international transport corridor (hereinafter referred to as ITC), which connects India, Iran, the Gulf countries through the countries of the Caucasus and Central Asia with Russia and the countries of Europe. A brief review of scientific publications on the subject under consideration allows to draw a general conclusion from opinions of various authors: it is necessary not only to develop the transport corridor infrastructure, but also to solve organizational, regulatory and tariff issues. The main advantage of North–South ITC is that most of the route passes by land and the route itself is shorter than the sea route, providing thus significant acceleration of cargo delivery.As a result of development of the railway network in the Caspian region and Central Asia, today there are several options for the ITC route. The western route to Iran through Azerbaijan was examined in more detail. It is expected that the missing railway section Astara–Rasht will be completed in the nearest future. Test shipments of goods from India to Russia (and vice versa) have already been carried out via western route. The characteristics of the route options by transportation distance, delivery time and cost of cargo transportation are given. Today, cost of transportation along the western branch of ITC significantly exceeds cost of sea transportation through the Suez Canal. This and other factors, reducing the efficiency and competitiveness of transportation via ITC, it is proposed to first organize container transportation on ITC section between Russia, Azerbaijan, and Iran. Such transportations might be especially in demand for food products (including perishable goods) in direction from south to north. To this end, it is proposed to organize a scheduled container train service along Astara–Moscow–St. Petersburg route using new Freight Express 2.0 transportation technology.

This study was initiated with a goal of improving the bus scheduling model using the past data of “smart card”. Traffic congestion level of Seoul is keep aggravating and it also has negative influence on air pollution and our health. Additionally, this heavy traffic causes high congestion costs. The continuous quantitative growth of the public transportation system brings the necessity of its efficient operation system for its future qualitative growth. The improvement of operation system is necessary also to improve public transportation operation cost efficiency of Seoul. In other words, the systematic planning is necessary for maximizing passengers’ satisfaction level and the public transportation operation cost efficiency of Seoul. The current allocation interval of Seoul bus system is designed based on the empirical data of the past, which is incapable of immediate response to rapidly changing passenger demands. This research analyses passengers’ behaviour and makes a proposal for the traffic network operation by analysing the “traffic card (smart card) big data”, which comes from over 90% of the passengers so as to be flexible in dealing with rapid changes in demand.

The article deals with different transport modes for regular mass freight transportation, their efficiency evaluation is conducted on the bases of cost, operational and environmental properties. Introduction. Due to demand in ensuring mass transportations between Southeastern Asia and Europe, there is a topical issue of efficient application of different types of ground transport. There is a request rising, to use cutting edge achievements in technology, to increase speeds of freight transportation for long distance and their safety and environmental friendliness enhancement. Analysis. Consideration of cost properties of application of different transport modes for mass freight transportation allows revealing that the lowest infrastructure cost is typical for conventional railway transport; the lowest prime cost of transportation is ensured by maglev transport with permanent magnets of the “RosMaglev” technology; the lowest commercially profitable mode of transport for today’s level of science and technology is vacuum transport. Operationally, the leading project is “RosMaglev”, with the vacuum transport having the lowest operational efficiency. From environmental and carrying safety points of view, railway transport has gone pretty far in the recent two decades. However, a more sustainable and safe one is the maglev and vacuum modes of transport, which is explained by lack of emissions and other types of pollution, including noise pollution. In terms of safety, maglev transport is the most competitive mode of transport. Whereas, vacuum transport is the most dangerous one. Results. For mass freight transportation, the most promising mode of transport is the “RosMaglev” permanent magnets maglev transport, according to the authors. The technology allows significant increase of infrastructure construction costs. The second most promising mode is conventional railway transport. However, if the demand in transportation is low and the energy efficient traction rolling stock is implemented, the high-speed freight railway transport may be highly competitive, especially in countries with developed high-speed railway network. The vacuum transport holds firmly the third place. Conclusion. The relevance of maglev transport implementation for mass freight transportations is obvious. The maglev technologies now in use in many countries for carrying passengers have proved profitable, safe and convenient. Technical “maturity” of these technologies allows considering all points and factors when constructing maglev freight lines which is very topical due to increasing need in searching transport routes alternative to sea routes.

The effectiveness and efficiency of public transport should be a priority for transportation in developing cities. Despite the efforts from the government to improve public transportation, in Jakarta City, Indonesia, there is still 9.93% increase of private vehicles annually per year. In detail, contributor for increasing vehicles in Jakarta is motorcycles with an average annual increase of 10.54% every year, followed by an increase in the percentage of passenger cars by 8.75%. In contrast, the number of public transportation increased only by 1.74%. This research did the evaluation for public transport service in Jakarta by availability and accessibility for them. Neighborhood analysis and Proximity analysis used in this research. The results of the research showed that major problems in public transportations in Jakarta City are the coverage area of the service, route connectivity, and its accessibility for public facilities. There are only 7.78% for coverage area by flexible bus stop service with average walking distance by 300 m. Thus, there are some areas that are not passed by public transport routes, for about 18.5 million people live in blank spot area.

We give a solution of the optimal transport problem in groups of type H when the cost function is the square of either the Carnot–Carathéodory or Korányi distance. This generalizes results previously proved for the Heisenberg groups. We use the same strategy that the one which was developed in that special case together with slightly refined technicalities that essentially reflect the fact that the center of the group can be of dimension larger than one. For each distance we prove existence, uniqueness and give a characterization of the optimal transport. In the case of the Carnot–Carathéodory distance we also prove that the optimal transport arises as the limit of the optimal transports in natural Riemannian approximations.

Full textAbstract:
Overloading of road freight vehicles accelerates road damage, creates unfair competition in the transport market, and increases safety risk. There is a dearth of research on the mining of data of highway Freight Weight (FW), and this paper therefore aims to discover factors affecting road freight overloading based on highway FW data, with a view of developing strategies to mitigate such occurrences. A comprehensive sampling survey of road freight transportation was conducted in Anhui Province (China). Vehicle Characteristics (VC), Operation Mode (OM), and transportation information from a total of 3248 trucks were collected. In order to take advantage of the strengths associated with both statistical modelling techniques and non-parametric methods, a Classification And Regression Tree (CART) technique was integrated with Binary Logistic Regression (BLR) to reveal the factors affecting road freight overloading. The classification efficacy test shows that the BLR–CART method outperformed the BLR method in term of accuracy. It is also revealed that the factors affecting overloading of freight vehicles are the Type of Transportation (ToT), Rated Load (RL), OM, FW during the investigation period, interaction between RL and FW, and interaction among RL, FW, and Average Haul Distance (AHD). Road transport authorities should pay greater attention to these factors in order to improve efficiency and effectiveness of overloading inspection.

Refractory severe hemodynamic or respiratory failure may require extracorporeal membrane oxygenation (ECMO). Since some patients are too sick to be transported safely to a referral ECMO center on conventional transportation, mobile ECMO transport teams have been developed. The experiences of some ECMO transport teams have already been reported, including air and international transport. We report the first French pediatric international ECMO transport by aircraft. This case shows that a long distance intervention of the pediatric ECMO transport team is feasible, even in an international setting. Long distance ECMO transportations are widely carried out for adults, but remain rare in neonates and children.

This article provides the analysis of the possibilities to instal new technologies in the Lithuanian railways the building of a high speed railway line I in Kreta corridor. It is advisable to project this line as a mixed one, i.e. intended for both passenger and goods traffic. The research carried out by the author has shown that light transport dominates in passenger transportation among four cities of Lithuania Vilnius, Kaunas, Klaipeda and Siauliai, which transports even 81,3% of direct passengers. Buses carry 14,9% and only 3,8 % of passengers are carried by railway transport. Therefore the main problem public transport is facing is to“get the passengers back” from light transport means, i.e. cars. The prospective railway and road transport markets in local, intercity and international passengers' transportations are also established in this work.

The competitiveness of a travel chain largely depends on the travel conditions along the sequence of journeys within the chain. This paper shows a method to analyse and to optimize the service quality along a travel chain. Travel comfort is a very important qualitative feature of the public transportation service, where travel comfort is used in a broader sense to describe ride quality and transfer quality including mobility, information, safety, security, and naturally comfort aspects. The analysis of travel comfort in the literature regards public transportation services. Several synthetic indices, which consider user judgment about service aspects, were developed to describe travel comfort, and comprehensive analyses have been published. However, to describe the competitiveness of the public transport the focus from the individual services should be moved toward the integrated service of the travel chain from the beginning to the end. The characteristics of travel comfort along the travel chain should be described and the location and rate of necessary interventions should be identified. In this paper we analyse the travel comfort features of travel chains. This paper proposes a method, which describes the travel comfort characteristics with synthetic indices based on the individual comfort indices of travel components, and uses a fuzzy approach to give an overall analysis of comfort conditions along the travel chain. The proposed method helps to identify the quality fluctuation and the weak points of a travel chain and makes the attractiveness of alternative travel chains comparable. An illustrative case study was carried out for one of the major transportation corridor of Budapest (Hungary), to exemplify the approach, where the validity of the method was tested as well. The results confirmed the usefulness and applicability of the methodology; by its application very valuable insights can be gained regarding the location and type of the necessary interventions. The results of our research are helpful to evaluate the actual service level of sustainable alternatives of individual car usage and to promote modal shift towards sustainable transportation modes.

The article deals with the relationship between media and transportation infrastructures and analyzes their links to the concept of mobility. It examines the assumption that infrastructure systems themselves are mobile, in the sense that they develop and have to be maintained constantly. According to such a perspective, they are to be considered not primarily as “structures,“ but as specific processes of mobilization (infrastructuring) that constitute the basis for mobility in the sense of transport and movement. Drawing on historical knowledge of transportation, it will be shown that a broad understanding of traffic as exchange, communication, and transportation has narrowed in the twentieth century, whereby the originally implied idea of transport as transformation became suppressed. Recent approaches in mobility studies, Science and Technology Studies (STS) and Actor-Network-Theory (ANT) can be combined in a fruitful way to unfold the specific dynamics of infrastructure as a process of mobilization (Callon) and technical mediation (Latour).

This study is aimed at increasing the efficiency of multimodal freight transportations by forming a risks management system based on the identification of transport risk factors, methods of their measurement and management both at the projecting (planning) stage of the multimodal route and further on – in order to assess their possible impact on the efficiency of freight transportation in general. The authors examine the problematics of multimodal freight transportations organization in the context of transport risks management, which provides for the choice of such an option of management influences on elements of the transportation system (logistics centers, transport hubs, various types of transport, freight transport units, specific transport companies and their rolling stock, containers, etc.), in which freight delivery would be carried out in terms of the most efficient and qualitative indicators under the known initial conditions and existing restrictions. The article substantiates the proposals development in view of optimal relationships between elements of multimodal freight transportations on the basis of an efficient risks management system, which is a special type of management activity directed towards mitigating the influence of risk groups, determining the permissible (acceptable) level of risk based on methods that allow avoiding losses arising as result of a particular risk. A methodical approach to choosing the optimal multimodal transport-technological scheme is proposed, which allows considering subjective criteria (completeness of service, reliability, etc.) as decisive under the condition of relatively equal cost and time of alternative freight delivery options and in the context of permissible values of such objective criteria as storage conditions, high-speed mode of transportation in the territory of a particular country, region, city, axial load, climatic conditions, ecological restrictions, etc. At the scientific-methodological level, the stage of the decision-making process is generalized along with the separation of relevant goals in the context of managing transport risks in multimodal freight transportations, the observance of which will guarantee to ensure the acceptance by the operator of multimodal transportations of a rational and secure transport-technological scheme of freight delivery.

The ridesourcing services market in China has recently experienced significant changes, which stem from its legalization and management policy. These changes impact multiple stakeholders of this market (e.g., drivers, passengers, government, competing services) and present them with new opportunities and challenges. This paper develops an evolutionary game model to analyse the Evolutionary Stable Strategy (ESS) between the Transportation Network Companies (TNCs) and drivers. The new model is explored and analysed with simulation experiments to observe the dynamic route of multiple stakeholders. The theoretical research and simulation results indicate that under the authorities’ control over the TNCs, when the net income under strict management is higher than that of the loose management for the TNCs, the final ESS is “Legal Operation, Strict Management”. When the net income under strict management is less than that of the loose management for the THCs, the strategy of “Illegal Operation, Loose Management” may gain popularity and continue to grow; in this case, the ESS may also not exist. The model indicates the strength of the government’s control plays a significant role in leading the achievement of “Legal Operation, Strict Management”. As a consequence, to achieve the perfect evolution of “Legal Operation, Strict Management”, it is necessary for the government to impose a greater penalty on illegal drivers and ensure appropriate compensation measures. The results of the study provide a useful reference for the sustainable development of the ridesourcing services market.

Due to its geographic location and developed transport infrastructure, Ukraine has a significant potential in the development of cargo transportation, primarily in international traffic, in particular as a transistor country in the logistics chain of trade between Asia and Europe. The possibilities of railway transport for the organization of transportation between the countries of the European Union and Ukraine are not used to the full extent, since there is a number of technical reasons of the transport systems incompatibility between Ukraine and European countries. In the course of the research, methods of analysis and synthesis were used to study prospects of the European and domestic system of international railway transportations, the experience of creating, operating and optimizing these systems. To compare the above mentioned options, the authors developed a model for predicting and assessing the efficiency of railway transport from the border of one state to the border of the other one.

Fixing the accessibility is a standard issue of transport analysis, which can be of interest to many socioeconomic applications. In the paper we propose and discuss accessibility and other indicators‐based urban transport system analysis and GIS (geographic information systems) calculation method for indicating problematic transportation zones in Vilnius city. The main parameter is time‐based accessibility from/to the central part of Vilnius and other transport zones in the city. Created GIS application computes the ranks for transport zones of Vilnius city according to accessibility and Vilnius statistics in these zones (street network density in city zones, number of working places, number of equipped parking places, number of attractive objects in transportation zones). The GIS decision support system is based on 2 calculation methods Topsis(Technique for OrderPreference by Similarity to Ideal Solution) and SAW (Simple Additive Weighting). Application of transportation zones analysis improves the quality of basic environment statistics and fills many data gaps related to urban statistics, providing information to decision‐makers and the general public concerning key factors determining the state of urban transportation environment. This paper outlines criteria and models used in Vilnius to develop urban transportation indicators and the reasons why the selected indicators represent the first important step to achieve a comprehensive system of indicators of urban transportation sustainability in Vilnius city. This model could be integrated in systems of urban transport planning and sustainable development planning.

Topicality. The urgency of the study is due to the fact that in Ukraine the volume of cargo transportation using multimodal technologies is growing. Therefore, increasing the efficiency of multimodal transportation using the latest methods of their optimization is timely. This is especially true for those modes of transport whose share in total freight turnover is relatively small.
Aim and tasks.The main purpose of the study is to develop theoretical and applied provisions and algorithms for finding the optimal solution for several target functions with different measurement scales to increase the efficiency of multimodal transportation, in particular, with the alternative use of different modes of transport. To achieve this goal, the following tasks arose: to study the impact of the monopolization of the transportation market by certain modes of transport on the reliability and efficiency of transportation; solving the problem of optimization of freight transportation from the national or general industry point of view; study of the importance of the development of inland water transport to increase the efficiency and reliability of multimodal transport; creating an algorithm for finding the optimal solution for several target functions.
Research results.Theoretical and applied positions of search of the optimum decision on several target functions with different scale of measurement for increase of efficiency of multimodal transportations, including, at alternative use of different types of transport are investigated. The study proved that the choice of only one of the traditional target functions of transport companies - the cost or time of transportation does not guarantee its effectiveness without assessing the risks of transportation of goods. An algorithm for selecting the optimal solution for several objective functions is proposed. To do this, we used the method of finding the extremum of each of them by its own nontrivial subset. It is proved that these sets, in the general case, are not identical, so to find a solution for several objective functions complicated by their different dimensions, the principle of compromise must be used.The study established a significant degree of monopolization of the transportation market by certain modes of transport and indicated that to solve the problem of optimization of freight transportation from the national or general industry point of view requires equalization of disparities in freight turnover by mode of transport.Conclusion.Analysis of the results of the study allows us to draw the following conclusions: to use the resource to increase the efficiency and reliability of cargo transportation, especially for multimodal transportation technologies, it is necessary to equalize the disproportions of cargo turnover by types of cargo transportation to avoid monopolization of the transport market. To increase the efficiency of transportation, the latest algorithm for selecting the optimal solution for several target functions is proposed. The introduction of this algorithm to optimize multimodal transportation in scientific and practical problems will allow to take into account the risks and find a compromise solution in complex problems of finding solutions for the transportation of goods.
