The major causes of investment riskiness into transport infrastructure relate to international economy instability, lack of clearly defined and accurate information on the overall processes of international intermodal transportation, absence of objective information due to inconsequent market research as regards interpretation of economic, political and other aspects. Assessment of objective integrated investments into public transport sector as a very specific branch of economy should necessarily be evaluated as multiple indicators affecting different spheres of community, and the final solution should be drawn when all multi-criteria indicators are well appraised. Economy based grounding of the optimal choice from all possible variants when solving specific tasks of the transport sector, depends on the economic expediency of the constructed subject. The main factors of effective usage of investments become apparent in the process of solving the task of road or railway network development optimisation.
Keywords: transport, infrastructure, investments, efficiency, risk

The scientific analysis of currently used assessment principles of the development on urban transport systems; subsystems on vehicles, passenger and freight transportations, special public services, pedestrian and bicyclists has been carried out. Each subsystem needs technical infrastructure, the set of informational and traffic control means. Moreover quantitative and qualitative development of transport infrastructure is necessary for appropriate operating of whole communication system. Unfortunately an increase in the level of automobilization, growing transport flows in urban territories and decreasing investment for the development of transport infrastructure are the main barriers for urban development. An uncontrolled increase in automobilization changed the character of the usage of urban territories, urban structure, stimulated the process of agglomeration and formed new problems. The results of expert evaluation and statistical analysis highlighted the influence of each subsystem on the sustainable development of whole urban transport system by technical, traffic safety, social-economic, environmental and other specific aspects. Objects of technical infrastructure that should be treated as infrastructure of urban road transport system were identified. The results of statistics analysis allowed determine features of separate objects necessary to evaluate; assess and adjust separate stages, key principles and quantitative and qualitative criteria of assessment of the development on urban transport systems infrastructure.

During the last two decades the European airport industry is liberalised and turned to competitive market environment. This fact attracts an increasing scientific and practical interest to analysis of airport efficiency and its determinants, as well as different aspects of airport competition. This paper contains a critical review of existing researches in these two areas – airport efficiency and spatial competition among airports. We analysed modern approaches to airport benchmarking, their advantages and shortcomings, and systematised a wide range of related academic studies. We paid special attention to empirical researches of spatial competition as a factor affecting airport efficiency. Despite the fact of a well-developed theory of spatial competition and signs of its growing effects in the airport industry, we discovered a lack of studies devoted to the relationship between airport efficiency and spatial competition.
Keywords: airport efficiency, benchmarking, spatial competition

In the paper, various opinions of Lithuanian and foreign authors of scientific publications are reviewed and the criteria for assessing competitiveness of road transport are discussed upon. On assessment of competitiveness of services provided by Lithuanian road transport enterprises, not only technical options are taken into account. It is proposed to assess competitiveness of enterprises upon taking into consideration the total set of services provided as well as their quality and the marketing level of the enterprise. In the paper, the factors impacting competitiveness of road transport are discussed upon and the research works required for objective assessment of competitiveness of road transport are foreseen. A model for assessing competitiveness of road transport enterprises realized by the authors is provided. In the end of the paper, conclusions and recommendations are provided.
Keywords: competitiveness of enterprises, competitiveness assessing, concordance, AHP method

In the paper the multimodal freight transportation system with a finite number of known alternatives, defined by the routes and modes, is considered. The objective of research is to suggest the approach for evaluation and choice the alternatives of cargo transportation. The following main tasks are considered: choice of indices characterizing efficiency of multimodal transportations, formation of optimization criteria of the multimodal freight transportation, construction of the model of the multimodal transportation system, calculation the performance criteria of cargo transportation. The study presents the Analytic Hierarchy Process (AHP) as the most suitable approach for comparative evaluation of different routes and modes of cargo transportation.
Keywords: multimodal freight transportation, logistic system, business-process, criteria of optimization, route, Analytic Hierarchy Process

Alongside their core service, i.e., passenger transportation, air carriers are nowadays providing numerous extra services, which are not directly related to transport. On the one hand, airlines are enlarging the scope of paid services provided on board an aircraft by, among other ways, splitting the air ticket fee and singling out the costs of such services as catering on board, checkedin luggage, airport check-in, etc. On the other hand, airline companies tend to provide mass services to their sales partners – ground transportation, car rental, insurance, hotel booking, etc. Provision of both the core and the extra services is closely connected with computerized reservation systems and the corresponding agent and customer access networks. These systems and networks form the basis of IT channels of service distribution. The present paper analyses the indicators and development trends of air transport services in combination with the development of service distribution channels and the information technologies lying at the basis of such channels. The paper also describes the structure and IT support of distribution channels. The authors have paid attention to the potential qualitative changes in the structure and possibilities of distribution of air passenger transportation services in view of the Next Generation Network (NGN) concept whose implementation has been started in the world.

The classical scientific literature dedicated to transport modelling has emphasised three levels of detail on which traffic models could be created. These levels are: microlevel, mesolevel and macroscopic level. Microscopic and macroscopic modelling are well known and widely used. The term ‘mesoscopic modelling’ has been interpreted by different scientists in different ways. In general, mesoscopic traffic flow models are understood to be models where traffic flow is described with a high level of detail, but at the same time flow behaviour and flow interactions are presented with a low level of description. The previously proposed new simulation approach (called ‘mesoscopic simulation’) was applied to traffic flow simulation. All the described models were implemented using Microsoft Excel and VBA. However, the practical application concerns that to construct more sophisticated models Microsoft Excel and VBA could not be used, because of programming complexity. The main goal of this paper is to present examples of the application of the discrete rate approach of ExtendSim simulation software for traffic flow simulation. A literature survey has shown that the discrete rate approach is mainly used in logistics, but not in the area of transport area. So the tasks of this paper are to present the main techniques of model implementation using a discrete rate approach and to apply this approach to traffic flow simulation.
Keywords: Discrete rate, mesoscopic models, traffic flow
