Introduction. The experience of developing the economies of the developed countries of the world suggests that it is directly related to the evolution of transport and infrastructure. In most of countries, intelligent transport systems (ITS) are under investigation as one of the scientific directions of the symbiosis of the economy - technology – telematics, and considered as the most effective tool for solving transport problems. The efforts of international organizations, state representatives in the field of transport, scientists, entrepreneurs and the public are aimed at such key areas as: significant increase in both the safety of transport on all modes of transport and capacity grows of the transport system of the country. Purpose. The goal of the article is to develop a single integrated approach to the definition of the term ITS and to provide a general classification system with details on the management objects. Methods. To achieve the goal methods have been used based on the systems approach, management theory and decision-making theory. The system analysis has been used to determine the scientific task. Results. In order to implement the tasks of transport management in terms of ITS, the system analysis of the field of research has been carried out in the article, including the systematization of the definition and the construction of a general classification system with details on the management objects. The analysis of the subject area of ITS usage has allowed establishing the main classes of the analyzed objects, to classify the tasks of monitoring characteristics, organization of management of transport flows and transportation process, information support for participants, organization of transport infrastructure management. Research of the literature sources allowed to form an integrated approach to the ITS classification system, which includes both systems introduced in the objects of transport infrastructure and in the management of transport flows. In the addition to the above, the main thing in the infrastructure objects is the terminal monitoring and management system, as well as the security management system. Conclusion. ITS is a new type of transport management systems that are gradually replaced by automated control systems. They are focused on modeling various cases and forecasting of dangerous situations and be used for decision-making tool in the condition of great complexity and large amounts of data. ITC can be considered as an important component of the modern integrated approach to improving the efficiency of the functioning of the country's transport system by expanding their information infrastructure: automated data collection on state of the system in real time, modeling direct and indirect operational impact on the formation and change of transport flows.

The role of multimodal transportation in the world market of transport services is defined in the article. Emphasis is placed on the significant pace of its development in a number of countries (first of all in the EU, the USA and China). It made it possible to minimize costs and increase interest to the countries in the international transportation system. It is established that development of multimodal (combined) transportation is considered to be promising in the growth of the transport system of Ukraine. International conventions and regulations of the world’s leading countries are analyzed. Typical features of multimodal transportation are singled out. Namely: implication of two or more modes of transport under one contract in the process of transportation; freight transportation under one document (through bill of lading); use of through tariff rate; presence of one of responsible parties – multimodal transport operator, that is responsible for freight from the moment of taking it under control up to the moment of its transfer to the consignee. Based on the study of the global trends in development of multimodal transportation, practices, which are of interest for further introduction in Ukraine, are defined. Namely: introduction of the effective transport policy in this field and creation of the regulatory base; development of multimodal transportation on the basis of the integrated approach, which provides for implementation of the relevant plans and programs; creation of multimodal transport system and new corridors; overcoming the infrastructural imbalance; construction of the modern multimodal logistic centers and their equipment; containerization of freight transportation; development of contrailer connections and expansion of the routes; improvement of services quality by introducing the latest innovative technologies for transportation process organization (use of electronic goods declaration; organization of digital transport corridors; electronic support of any chain of the freight delivery, use of the monitoring system for freight delivery control); implementation of the effective management system for risks arising in the process of multimodal transportation.

This article is devoted to the formation of theoretical foundations and methodological approaches of scientific coverage of economic and statistical problems of the functioning of urban passenger transport systems. The problematic is considered on the example of the city of Kharkiv. Public transport in Kharkiv is represented by almost the maximum number of types city trams, trolleybuses and metro, as well as private road carriers. The concept of consistency is based on the territorial principle and intermodality. The general indicator of the level of development of the territorial transport system is its balance. Unfortunately, the territorial transport systems of Ukraine are insufficient for the passage of existing traffic flows, and transport infrastructure facilities and rolling stock do not ensure the safe and comfortable movement of individual vehicles, public transport passengers, cyclists and pedestrians. Public transport does not provide all citizens with financially affordable and technically qualitative services and cannot be an alternative to individual cars. Traffic is not sufficiently regulated by existing traffic control means. Operated vehicles have a negative impact on the environment and create traffic jams. As follows from the study, this unsatisfactory state is due to the lack of independence and dependence of communal transport enterprises on subsidies from the city budget, unbalanced state policy in the field of tariff setting, insufficient rates of renewal of rolling stock and transport infrastructure, insufficient rates of introduction of non-cash payment for travel, imperfection of methods and ways to manage enterprises as a single intermodal system. Solving the described problems requires an integrated approach. First of all, this is the creation of a systemic management mechanism to create a balanced territorial transport system. This is what shows the relevance of the chosen topic and determined the choice of the direction of research in scientific and practical aspects. The research results will be used to improve the efficiency of the municipal transport.

The plasma membranes of most animal cells contain transport proteins which function to provide passageways for the transported species across essentially impermeable lipid bilayers. The channel is a passive transport system which allows the movement of ions and low molecular weight molecules along their concentration gradients. The pump is an active transport system and can translocate cations against their natural concentration gradients. The actions and interplay of these two kinds of transport proteins control crucial cell functions such as active transport, excitability and cell communication. In this paper, we will describe and compare several features of the molecular organization of pumps and channels. As an example of an active transport system, we will discuss the structure of the sodium and potassium ion-activated triphosphatase [(Na+ +K+)-ATPase] and as an example of a passive transport system, the communicating channel of gap junctions and lens junctions.
