Analysis of selected national ITS architectures and recommendations for the architecture for Poland

For the efficient functioning of intelligent transport systems, the integration of individual subsystems is crucial, both in terms of functionality and the scope of impact (local, regional, or national). This integration should be based on a hierarchy of dependencies: regional systems integrate locally operating systems, while the national system connects individual regional systems into one integrated structure. The basis for the effective implementation of such a system is a well-developed national ITS architecture. This study analyzes four selected national ITS architectures, which the authors consider the most representative. Based on the analysis, recommendations for the Polish national ITS architecture are presented.ANALISYS OF CHOSEN NATIONAL ITS ARCHITECTURES AND ASSUMPTIONS FOR ITS ARCHITECTURE FOR POLAND
The functional and territorial (local, regional and national) integration is the most important thing for efficiency of intelligent transport systems.
This integration should be realized due to present hierarchical structure: local subsystems are integrated by regional ones and national system joins the regional ones into the one integral structure. The basis of efficient of development this systems is the national ITS architecture. This paper is focused on analysis of four chosen national architectures. Based on this analysis the authors have prepared assumptions for polish solution.
