conclusions:

1. Implementation of opportunities by making use of advantages is possible due to:

? Awareness of businessmen about the importance of speeding up the production of information technologies and delivery of services:

? Favourable attitude of the Parliament and governmental institutions towards the information society and ITS development;

? Sufficiently dense network of transport and communications.

2. To use the opportunities for elimination of disadvantages is possible by: ? Creating the database of traffic accidents;

? Traffic management and control modernisation with the involvement of ITS, thus ensuring traffic safety and increasing road throughput capacity;

?Supporting the scientific research programmes and using the opportunities of ITS deployment by close cooperation with stakeholders;

? Using EU financial support for modernisation of road transport sector with the aim of solving traffic safety problem on the EU scale. 3. Threats would decrease with:

? Creation of an active road transport traffic safety system; ? Reduction of congestion in public transport;

? Enhancement of scientific research, technological development and innovations in the field of ITS.

4. Risk factors, if ITS deployment fails in the nearest future:

? Lithuania’s road safety improvement obligations in the context of EU membership will not be carried out;

?Lithuanian roads will not meet technical and quality requirements of Trans-European road transport network;

? The opportunity can be lost for using EU funds specially designated for the development of information technologies and telecommunications and for the integration of these measures into the ITS development;

? Lithuania may remain among the backward countries and may lag behind due to the more rapid development of ITS in foreign countries. 5. Possible technical solutions of ITS deployment

Firstly, with the aim of integration of Lithuanian ITS into the EU system of ITS it is necessary to orient to the KAREN project , which is a project for elaboration of ITS architecture guidelines for deployment of active and operating ITS in the EU by 2010 and later.

In the process of creating the ITS architecture for public organisations and business stakeholders it is necessary to decide upon the form of the architecture which should be created. Such form may be one of the following three types:

? Structure architecture, i.e. the architecture consisting of consumer demands and functional aspect. It may be used in the process of creating the architectures of the following two types and it is the only type of architecture really applicable for national level architectures.

? Legacy architecture having physical, communication and other aspects plus capacities. It may be used on the national, regional and local levels with concretisation of ITS deployment needs. The content of physical aspect can be fixed or limited .

? Service architecture, which is like the legacy architecture, however it only supports/maintains the exclusive service, as for example management of road accidents, travel information, public transport management, etc.

ITS architecture has to be developed with the aim of coordination of all ITS components into one framework structure, so that their interoperability could be reached in the delivery of necessary services to customers. Specific architecture can be expressed by multiple forms. It is necessary that stakeholders should understand and approve the concepts and functions that inform the development of ITS operations and institutional architectures. On their part, ITS designers have to work with logical, physical and telecommunication architecture that will present operational and functional requirements.

Lithuanian ITS architecture should be sufficiently enough adjusted to defined local requirements. This will be expressed with the view to the functional requirements, logistical architecture and organisational architecture.

Each aspect of architecture is related to ITS implementation plans and can precisely indicate where it will be important to ensure interinstitutional agreements of common operation, or to define the value of common regional standards used. Properly carried out and well explained to society the ITS architecture analysis will demonstrate the whole range of interrelations necessary for operators in different institutions with the aim of efficient delivery of ITS services. Examples:

? Interoperability of intended new or of modernised existing ITS traffic regulation systems and
