Compatibility of Users Requirements - a Prerequisite for Successful ITS Development of Countries of Southeastern Europe
The implementation of intelligent transport systems (ITS) is becoming more complex and it is becoming more difficult to realize it successfully. The methodology of the European Framework ITS Architecture (FRAME) has been developed in accordance with the standards and practices of systematic engineering, and it should be used in the early stages of ITS life cycle. The European framework ITS architecture combines the users requirements and functional aspects and it can be used successfully for creating the national ITS architectures because it is independent of any particular technology and physical design. This approach to the development of national ITS architecture of Southeast European countries, which implies high compliance of users ITS requirements, enables the creation of frameworks that insures institutional and technical connection during the implementation of ITS projects. The development of national ITS architecture without the compatibility of the users requirements and without using the methodology of the European framework ITS architecture would result in much higher costs of ITS development and deployment, difficulties in achieving system interoperability, and difficulties in the process of upgrading and updating of national architecture throughout the ITS life cycle.
