The paper presents an analysis of measures to be taken for development of sustainable transport system. Increasing traffic intensity unavoidably requires faster development and modernisation of transport infrastructure, which means not only larger investment but also better transport policy and introduction of more advanced solutions, such as promotion and deployment of ITS - intelligent transport systems and services. In Lithuania for development of a modern transport system meeting the EU standards and criteria, the key priority is given to development, rehabilitation and modernisation of those transport infrastructure objects that form an integral part of TEN-T. Another as much as significant task is to improve road, railway, water and multimodal transport infrastructure of national and regional significance in order to cope with the growing mobility needs of the society, promote development of business and tourism, and increase competitiveness of the economy. In recent years the ITS deployment policy have been strongly promoted in the national level. Road safety is a further area where substantial improvement is needed, despite significant achievements in the past. Application of ITS is seen as one of the most effective tools in order to improve traffic safety and other areas of transport.

Deployment of Intelligent Transport Systems and Services (ITS) has been strongly considered as crucial element of improved accessibility for passengers with reduced mobility. Intelligent transport systems in the light of improving an access to urban transport for passengers with reduced mobility are analysed in the article. The need of deployment of these systems in three areas ? information, infrastructure and vehicles is emphasized and practical examples are provided. Only in the case if intelligent transport systems are deployed in all the three areas, a seamless transportation for the disabled people is ensured. The aim of the research is to evaluate solutions, encouraged by the EU transport policy and proved by a good practise that might be implemented in Lithuanian urban transport system. These solutions are also based on results of questionnaire, accomplished by the author.

All real systems work in disturbances conditions. ?Disturbances? term belongs to special category of entry values which are not known before and do not make subject to control, it means they are uncontrolled entry signals. Disturbances are an important element of systems regulation, because usually lead to unexpected effects in functioning of steered systems. An alternative approach has been proposed in this article in disturbing signals description, related on theory of wave disturbances, which allow describing wide disturbances scale, occurred in suspensions of active vehicles. Disturbances models based on new wave interpretation can describe wide class of real, indefinite disturbances which occur in suspensions of active vehicles.
Keywords: suspensions, active vehicles suspensions, wavy interpretation of disturbances, Laplace transform random disturbances

The purpose of the paper is to present the methodology and its implementation results in the field of statistical research of TTI study process trends by use of analytical system. The actual analytical system (AS TTI) for data maintenance and analysis was created at Transport and Telecommunication Institute (TTI) based on the OLAP principle . The paper represents experimental results of the analytical system implementation for statistical research of study subjects' interconnections for transport and logistics educational programs. Advanced technology allows users to perform a multidimensional data analysis for decision making purposes. The system uses independent Data Marts, which are constructed basing on information delivered from actual TTI Information System (OLTP). The paper emphasizes one of the analytical tasks of study processes management at the university, which has been solved using the AS TTI Data Marts "Analysis of examinations marks for study subjects at different study programs". As the example of the suggested methodology some correlation coefficients were calculated and analyzed to characterize examination marks interdependency between study subjects for several educational programs in the transport and logistics area. As the result factually existing study subject interconnection was recognized on the base of correlation analyses. The analytical methodology implemented in the AS TTI was recommended as an eventual tool for investigation of study subjects? interconnection, aimed to improve the quality of educational programs.
Keywords: the University Analytical System, OLAP-technology and Data Marts

Currently in the city of Riga there are several parallel, independent of each other, networks for delivery goods. It is noteworthy that, unlike the major networks, companies doing outsourcing cannot provide the routes full load vehicles and the best routes. In the central part of the city near the same streets perform different trucks delivering goods to customers of neighbouring addresses. The movement, parking and downloading of vehicles produced during the working day and during peak hours, sometimes without taking a single lane road. This creates additional problems for urban traffic, pedestrians and the urban environment. The situation could be improved by creation of a virtual segment of intelligent transport system, planning the work of small transport companies (SME) that would work on outsourcing of logistics centres. The concept of such a system is in creation of the Internet-portal for linking customers and freight transport companies.
